Poke cakes have always been a family favorite because they’re fun to make and oh-so irresistible! Along with our strawberry poke cake and strawberry jello cake recipes, it’s always popular especially for summer barbecues and get-togethers.

Wen serving, try to cut the cake through the holes for a beautiful presentation of blueberry sauce dripping down the cake. So mouthwatering!

Ingredients

Here are the six ingredients you’ll need to make it:

  • Cake mix: One box of lemon cake mix is ideal, but you can use white cake mix if you prefer and mix in 1 teaspoon of lemon zest for flavor.
  • Blueberries: I recommend fresh for the best flavor, but you can use frozen blueberries in a pinch.
  • Sugar: Granulated sugar to sweeten the blueberry sauce. You can substitute stevia/erythritol for fewer calories if you prefer.
  • Lemon: Freshly squeezed lemon juice for the blueberry sauce, plus some lemon wedges for decoration.
  • Cornstarch: This is for the thickening the blueberry sauce.
  • Whipping cream: This is the heavy cream for the cake topping. You can use thawed Cool Whip or whipped topping if you prefer to save time.

How to Make a Lemon Blueberry Poke Cake

This recipe starts with baking the cake in a rectangular baking dish. Just follow the package directions and it should be ready in about 20-25 minutes.

While it’s baking, you can make the blueberry sauce by simmering blueberries with lemon juice, sugar and cornstarch on the stove over low-medium heat.

Once the cake has cooled slightly, poke holes across the surface using the handle of a wooden spoon. For certainty, the holes should be about 1/2-inch wide, an inch deep and spaced an inch apart.

Spread the blueberry sauce across the surface, pushing the blueberries into the holes. Once the cake has cooled completed, spread whipped cream across the top and you’re done!
