These no-bake Brownie Brittle Birthday Cake Icebox Cupcakes are a light and delicious treat made from crisp brownie brittle and luscious whipped cream! They’re super easy to make and look so cute and pretty!


  • 2 cups (480ml) heavy whipping cream, cold
  • 1 cup (115g) powdered sugar
  • 1 1/2 tsp butter extract
  • 3/4 tsp almond extract
  • 23 bags Chocolate Chip Brownie Brittle, (4 oz bags)
  • Sprinkles


  1. Freeze metal bowl and whisk for 15-20 minutes to get them good and cold.
  2. Remove bowl from freezer and add cold heavy whipping cream.
  3. Whip on medium-high speed for a few minutes. Cream will initially bubble a little bit, then start to thicken.
  4. As the cream starts to thicken, add the powdered sugar and extracts.
  5. Whip until stiff peaks form, for a total whipping time of about 5-7 minutes. Make sure not to overmix. It quickly goes from smooth whipped cream to curdled whipped cream, so watch it closely.
  6. To assemble the first icebox cupcake, place one brownie brittle square on a plate (or whatever surface you’re using) to form the base of the cupcake.
  7. Complete the first layer by piping, or scooping, a layer of birthday cake flavored whipped cream onto the brownie brittle.
  8. Create the second layer by placing another brownie brittle square on top, followed by another layer of birthday cake flavored whipped cream.
  9. Create the third layer and finish the first icebox cupcake by placing another layer of brownie brittle topped with whipped cream. Top with sprinkles.
  10. Repeat the layering process in steps 6-9, until you have 12 fully layered icebox cupcakes.
  11. Place cupcakes in fridge for at least 3-4 hours to set (overnight is even better). Keep refrigerated until ready to serve. Cupcakes should be good for up to 5 days.
