This lemon blueberry poke cake has the perfect for spring! It is made with white cake, blueberry puree, and topped with frosting that offers just the right amount of lemon!
This cake is easy to prepare and combines cake mix with fresh ingredients, making it a great dessert for any occasion without spending hours in the kitchen. You can definitely use your own homemade cake recipe, but I opted for a store bought cake mix for a quick dessert.

You’ll basically prepare the cake mix, add some lemon zest and let the cake bake in the oven. Then, you’ll make the blueberry puree while the cake bakes.

The blueberry puree is super simple to prepare in a food processor. If you don’t have one, combining all of the ingredients in a blender will absolutely do the trick.


Once the cake is done baking, you’ll poke holes all over the cake and pour the puree to cover the cake. You’ll let the cake chill in the fridge so it can soak up the puree.

Finally, you’ll whip up the frosting while the cake chills, and voila!
