Can you believe Easter is just a few days away? I am not entirely prepared, but I am excited to spend some time with family and reflect on the holiday.

If you are like me and not entirely prepared and are still looking for the perfect dessert, this is it! Spring is all about the fresh fruit and citrus and this cake combines both of them perfectly. Plenty of lemon and blueberry flavor, and as is the case with poke cakes, it’s quick and easy to put together. Plus, at ALDI the ingredients are easy to find and at great prices too!

This baby took several tries for me to get just right. The correct amounts of lemon and blueberry flavor were not as easy to achieve as I originally thought. The cake starts with a simple yellow cake mix. You could certainly swap it out for a homemade cake, but if you’re going for extra easy here, the mix is the way to go. Some lemon zest is added to the mix to get the lemon party started right in the cake!

How to Make Lemon Blueberry Poke Cake

While the cake bakes, I suggest putting together the mix that gets poured over top after it comes out of the oven. You’ll start with some fresh blueberries. Puree them by popping them in a food processor with a couple tablespoons of water and sugar. Once everything is pureed, you can pour it through a fine mesh sieve to get rid of the skin of the blueberries. You should end up with about a cup of puree after straining. Add the fresh squeezed lemon juice and sweetened condensed milk to the puree and mix everything together.

Once the cake comes out of the oven, poke holes all over with a straw or end of a wooden spoon, or something similar. Pour the lemon blueberry mixture over the holes and spread it around so it can soak into the holes and the cake. Set the cake in the fridge to cool and soak in all the juices and deliciousness!

Next is the frosting! It’s a light lemon frosting that finishes off the cake beautifully. To decorate the top of the cake, I added some lemon slices and additional fresh blueberries. Can we talk for a second about the blueberries at ALDI recently? I bought several extra containers because they have been so big, juicy and and at a great price lately! Pile those suckers on there!

This cake was a big hit! I love the purply-blue color from the blueberries with the lemon yellow. The moisture from the lemon juice and blueberry puree mixture is off the charts and the flavor is perfectly sweet, fruity and just a bit tart. It was another hit with our church group that even the dieters broke their diets for. 🙂

    I really want to try this recipe, but I live in Norway and we don’t have the Yellow cake mix you use. Can I just bake some plain cake instead, and add the lemon and blueberry? Or is the cake mix essential for this to turn out right?

    1. Lindsay

      I personally really like the yellow cake mix with this one, but if you don’t have it, you can certainly use a white cake.

  2. Kristi

    Is it necessary to refrigerate the cake while it cools and absorbs the blueberry mixture? It’s a hassle to deal with the condensation from the warm cake in the cool frig. I have seen other recipes for poke cakes that don’t call for the immediate refrigeration. Thanks!

    Best lemon frosting ever! I just finished frosting the cake and it is 10:50 at night, and I seriously licked the whole bowl clean. Can’t wait to try it with the cake and filling tomorrow at our Bible study get-together!

    A lemony triumph, Lindsay!  I made this delightful cake for Easter and everyone loved it.  I was lucky enough to get leftovers, and it’s even better the next day 🙂  I will definitely make this again.  It is totally worth breaking a diet for!
