Why You’ll Love This Funfetti Cookie Cake

If you love cookie cakes and regular cakes as much as I do, and often have a hard time deciding between the two, this cookie cake is for you. If you love cookie cakes, but are a little bored with regular chocolate chip cookie cakes, this cookie cake is for you. If you simple love cookies, this cookie cake is for you.

This is one of my all-time favorite cookie cake recipes. I love anything Funfetti flavored. And not just vanilla with sprinkles added, but actual Funfetti cake batter flavor. While I bake mostly from-scratch these days, I grew up on cake mix and there’s just something about that cakey flavor that gets me every time. So naturally, I needed a cookie cake that included that flavor. So this cookie cake was born. Aside from loving Funfetti and cake batter, here are a few more reasons to love this cookie cake.

  • Texture. This cookie cake may have the flavor of a birthday cake, but it’s all cookie. It’s wonderfully chewy and moist. It’s not fluffy like a cake, but instead is dense like a cookie. Pure perfection.
  • Flavor. As mentioned above, it’s like eating cake in cookie form. With some chocolate chips and white chocolate chips added in, it’s truly the best of two worlds coming together.
  • Easy to make. This cookie cake is so easy! You’re basically making a super simple cookie dough with a cake mix (kind of like cake mix cookies), pressing it into a baking pan, and baking it. You don’t even need to form it into individual cookies!
  • Celebratory. Made of colorful Funfetti cake mix with colorful sprinkles mixed in, this cookie cake screams “Let’s celebrate!”. It’s the perfect dessert for your next birthday, graduation, promotion, etc. You can even change up the colors for various celebrations.

Ingredients and Substitutions

Here what you’ll needed to make this cookie cake with cake mix. You’ll find precise measurements in the recipe card below.

Ingredients for Funfetti cookie cake.
  • Unsalted butter – The butter for the cookie cake should be at room temperature. If it is too cold or melted, it won’t cream properly with the sugars.
  • Light brown sugar and granulated sugar – The use of brown sugar instead of only using granulated sugar brings added moisture and depth of flavor.
  • Egg – Be sure to use a large egg, not medium or extra large.
  • Funfetti cake mix – I like the Funfetti cake mix, but feel free to switch it up. If you’d like to add your own color sprinkles for a particular celebration, use a vanilla cake mix and add whatever color sprinkles you like.
  • All-purpose flour – A 1:1 gluten-free flour would also work.
  • Salt – The salt helps deepen the flavors of the cookie cake.
  • Sprinkles – For a little added color.
  • White chocolate chips and chocolate chips – I used both but you could use all white chocolate chips or all chocolate chips.
  • Powdered sugar – Powdered sugar adds volume to your buttercream. You can certainly reduce the amount, but you won’t have as much buttercream and it may not pipe as well.
  • Heavy cream – Gives a creaminess to the buttercream and can be used to thin it out, if needed. Feel free to use regular milk or water, as well.
  • Gel icing color – The gel icing color is optional. Use whatever color you’d like! I tend to use Americolor gels because I love the little squeeze bottles, but when it comes to purple, I prefer the color of the Wilton gel.

Do I have to use cake mix?

In this cookie cake recipe, you do need a cake mix. But if you’d prefer to avoid using cake mix, feel free to check out my sugar cookie cake! It won’t have the cake batter flavor, but it’s a delicious soft and chewy cookie cake with tasty vanilla flavor that you can easily add sprinkles to.

How to Make Funfetti Cookie Cake with Cake Mix

Ready to get baking? Here’s a quick look at how to make this Funfetti cookie cake. Be sure to scroll to the recipe card below for more detailed instructions.

To make the cookie cake

  • Prep. Preheat oven to 350ยฐF, line the bottom of a 9-inch cake pan with parchment paper, and grease the sides.
  • Combine the wet ingredients. Cream the butter and sugars together on medium speed until light in color and fluffy. Mix in the egg and vanilla.
  • Add the dry ingredients. Mix the cake mix, flour, and salt into the dough is just well combined. Pull the dough together into a cohesive ball.
  • Add the mix-ins. Fold in the sprinkles, white chocolate chips, and chocolate chips.
  • Bake. Press the cookie dough into the cake pan. Press a few more white chocolate and chocolate chips into the top of the cake, if desired. Bake for 18-23 minutes.
  • Cool. Allow the cookie cake to cool in the pan before transferring it to a serving plate.

For the vanilla buttercream

  • Make the buttercream. But the butter until smooth. Mix in half of the powdered sugar followed by the vanilla and one tablespoon of cream. Mix in the remaining powdered sugar. Add more cream, if needed, to get the right consistency. Color buttercream, if desired.
  • Decorate. Pipe swirls of frosting around the outer edge of the cake and add some more sprinkles.

Tips for Success

  • Don’t skimp on creaming time. When creaming together the butter and sugars, do so until the mixture has significantly lightened in color and has become fluffy. This process incorporates air into the dough, helping to ensure that the cookie cake doesn’t come out too dense.
  • Don’t over-mix. When adding the dry ingredients to the dough, and then again when folding in the mix-ins, do not over-mix. This can cause the glutens in the flour and cake mix to overdevelop, giving you a tough, overly dense dessert.
  • Don’t over-bake. Bake just until the cookie cake isn’t shiny on top anymore. Remember that it will continue to cook a bit as it cools in the pan (see my next point) and that baking it past this point will give you a dry cookie cake.
  • Cool in the pan. You want to allow the dessert to cool completely in the pan. It will continue to bake and set a bit more during this time. The dessert will fall apart if you attempt to remove it from the pan before it is completely cool.
  • Get the consistency right. When making the buttercream, feel free to add a bit more heavy cream to the frosting to ensure the right texture. Check out my post on how to get the right frosting consistency for more information.

Fun Variations

There’s lots of room to experiment with this recipe to make it your own. Here are a few fun ideas for you.

  • Try a different cake mix. Funfetti cake mix is so celebratory and colorful but you could really use any cake mix here. Try chocolate cake mix, red velvet, or just plain vanilla!
  • Play with mix-ins. I went with sprinkles, chocolate chips, and white chocolate chips but you could go with any mix-in/s you’d like. M&Ms would be fun. So would your favorite chopped candy bar.
  • Consider a different frosting. I love the vanilla buttercream here but you could totally go with a Chocolate Buttercream or even a Cream Cheese Frosting instead.
  • To color or not to color. I went ahead and colored my buttercream purple but use any gel icing color you’d like (or no color at all).

Proper Storage

Seal the cookie cake in an airtight container (slice it first if necessary). You can store it at room temperature for about 24 hours, in the fridge for up to 5 days, or in the freezer for up to 3 months. If you leave the buttercream off, you can store the dessert at room temperature for up to 5 days.

This cookie cake is best at room temperature, so let it sit on the counter for a bit before serving. If you freeze the cookie cake, allow it to thaw in the fridge first.

Description

This Funfetti Cookie Cake is a tender, chewy cookie cake that’s made with actual Funfetti cake mix, chocolate chips, white chocolate chips, and sprinkles! It’s easy to make and is full of amazing cake flavor, but in cookie form! Perfect for a celebration!


Ingredients

Funfetti Cookie Cake

  • 3/4 cup (168g) unsalted butter, room temperature
  • 1/4 cup (56g) packed light brown sugar
  • 1/4 cup (52g) sugar
  • 1 large egg
  • 1 tsp vanilla extract
  • 15.25 oz box Funfetti cake mix
  • 2 tbsp (16g) all-purpose flour
  • 1/2 tsp salt
  • 3โ€“4 tbsp sprinkles
  • 3/4 cup (127g) white chocolate chips
  • 1/2 cup (84g) chocolate chips

Vanilla Buttercream

  • 1/2 cup unsalted butter, room temperature
  • 2 cups (230g) powdered sugar
  • 1/2 tsp vanilla extract
  • 1โ€“2 tbsp heavy cream
  • Gel icing color, optional

Instructions

Cookie Cake:

  1. Preheat oven to 350ยฐF (180ยฐC). Prepare a 9-inch cake pan with parchment paper in the bottom and baking spray on the sides. Set aside.
  2. Cream the butter and sugars together in a large mixer bowl on medium speed until light in color and fluffy, 2-3 minutes. You should be able to see the change in color and texture and know itโ€™s ready. Do not skimp on the creaming time.
  3. Add the egg and vanilla extract and mix until well combined.
  4. Add the cake mix, flour and salt and mix until the dough is just well combined. Do not over mix. Once itโ€™s well combined, use a rubber spatula to help it come together to form a more cohesive ball.
  5. Fold in the sprinkles, white chocolate chips and chocolate chips. The cookie dough will be thick.
  6. Press the cookie dough evenly into the cake pan. Press a few more white chocolate and chocolate chips into the top of the cake, if desired.
  7. Bake for 18-23 minutes, or until it isnโ€™t really shiny on top anymore. Donโ€™t over bake.
  8. Remove from oven and allow to cool completely in the cake pan, then transfer to a serving plate.

Vanilla Buttercream:

  1. To make the buttercream, add the butter to a large mixer bowl and beat until well combined and smooth.
  2. Add about half of the powdered sugar and mix until well combined and smooth.
  3. Add the vanilla extract and a tablespoon of cream and mix until well combined and smooth.
  4. Add the rest of the powdered sugar and mix until well combined and smooth. Add more cream, if needed, to get the right consistency.
  5. Add the buttercream to a piping bag fitted with a piping tip (I used Ateco 844) and pipe swirls of frosting around the outer edge of the cake.
  6. Store cookie cake in an airtight container. You can store it at room temperature for about 24 hours, then store in the fridge. Without the buttercream, it can remain at room temperature. I recommend serving at room temperature, since the cookie will firm up when cold. Cookie cake is best eaten within 4-5 days.

    Can this be made using a pizza pan? I want to decorate it to look like a pizza. If so what size do u suggest for a not too thin cookie cake?

    1. lifeloveandsugar@gmail.com

      Hi Karla! It’s hard for me to say, I’ve never tried that. Certainly it will bake, but it might spread a fair amount. I’d say whatever size you use, give yourself a good 3-4 inches at least around the edges to allow it to spread.

  2. Sabrina

    Can this recepie be done with normal cake mix? I cant seem to fund the funfetti cake mix in any shops around, and when I do eventually find it, its very expensive.
    It looks amazing!
    Thank you

  3. yvette

    hi there, i was just wondering if i could substitute the rainbow chip cake mix? and if you think it would come out good if i poured this recipe into cupcake liners and frosted , for my daughters wedding???? this is your funfetti cake batter white chocolate chip cake!!

    1. lifeloveandsugar@gmail.com

      Yes, any cake mix should work. And I think it’d be great as cupcakes – with or without liners. For an event, they might be cute without liners. Just grease the pan well. ๐Ÿ™‚

  4. Allyssa

    Hi! I just checked out both of your cookie cake recipes (funfetti and chic. Chip) I really want to make make one for my birthday and I really want your opinion on which one is best! Please please choose one….. even though you might love them both! Thank you!

    1. lifeloveandsugar@gmail.com

      Hi Allyssa! Have you seen the Triple Chocolate Cookie Cake and Oatmeal Raisin one? Just to make your decision harder. ๐Ÿ˜‰ Of course I love them all and which one I choose usually depends on my mood or the flavor preference of those I’ll be with. But if I had to choose for a birthday, I probably say the Funfetti one. Not only do I seriously love Funfetti, but it’s so festive for a birthday! ๐Ÿ™‚ Happy Birthday!

  5. Lea Gantt

    I have the dough in the refrigerator right now just waiting for me to bake it!! This looks delicious and my funfetti cake obsessed husband is thrilled I’m making this for him

  6. Lindsey

    Does your recipe call for the box that is 15.25 oz? I know they recently changed the box size and a lot of the recipes I used to use no longer work due to the smaller box size. Thanks!

    1. lifeloveandsugar@gmail.com

      Great question Lindsey! I can’t say I’m entirely sure. I think I made this recently enough that it was the 15.25 oz box, but now I think I’ll have to go make it so I can say for sure. I’ll be sure to update the recipe when I’ve re-made it so that there’s no confusion. Thanks for bringing it to my attention!

  7. Laura@Baking In Pyjamas

    I love funfetti and I love the colour if your icing, it’s so bright and vibrant. I came across your blog on Dandelion Wishes.

  8. Jane Barr

    Stores in our vicinity don’t sell “white chocolate chips”. Will the Nestlรฉ’s Premier white chips work as well.

  9. Lindsay

    I didn’t realize you had to refrigerate overnight! How long would you say the minimum hours in the fridge would be?

    1. Life, Love and Sugar

      Hi Lindsay! I’ve baked it after refrigerating for about 3 hrs before and while it was fine, the texture and flavors didn’t come together quite as well. I’d say 6-8 hours is best.

      1. Sarah A

        I made this last night. I am very amazed that I ended up with any dough to refrigerate!! I used a 8in pan and it was very thick. Either need to make two pans of it or invest in a 9in! Topped with the buttercream you posted and OHEMGEE! A sliver slice was all I could stand its so rich and fabulous!
        Thank you for sharing!!!! <3

    1. Life, Love and Sugar

      Hi Mandy, I’m not sure if it would work. It depends whether or not your mix is the same ratio of ingredients as a box mix. It took a little experimenting to get this one right.

  10. Emily

    I found it really hard to spread the batter after it sitting all night in the fridge. Maybe I did something wrong? I broke it in pieces, and arranged it in my spring form pan. I threw it in at 350 for 4 min and pressed it in my pan. It looks good still, its cooling now. Were you suppose to press it in the pan before you put it in the fridge all night? B.c mine was rock hard like break and bake cookies.

    1. Life, Love and Sugar

      Hi Emily! The dough definitely gets pretty firm. I also just break it apart and spread it in the pan. You could also leave the dough on the counter to soften a bit before you put it into the pan. Either way, it sounds like it has turned out well! ๐Ÿ™‚

      1. Emily

        Thank you I just tried it (the kids are napping) It was great! I run a daycare and all their little heads were popping up by the oven saying, “can we have some!!?” “Yes after nap”, so that way you can go home with a sugar rush! Hah Happy Mother’s Day! ๐Ÿ˜‰
        Also, we could have easily ate all the batter last night … It was sooo good! Thanks for a great recipe.

  11. Sally

    You are the cake batter queen! I’m blown away by this cookie cake. It looks amazing. I love the combination of white chocolate + cake batter. ๐Ÿ™‚ Your other cookie cakes look just as wonderful, too!
