How to Make It
Follow these steps to create your Lemon Blueberry Poke Cake easily.
1. Preheat the oven
Preheat your oven according to the cake mix instructions. Grease a 9×13 inch baking dish to prepare for the batter.
2. Mix the cake batter
In a large bowl, prepare the lemon cake mix according to the package instructions using water, oil, and eggs.
3. Bake the cake
Pour the batter into the prepared baking dish and bake until a toothpick comes out clean, about 25-30 minutes.
4. Cool the cake
Once baked, let it cool for about 10 minutes. This cooling period is essential before poking holes into the cake.
5. Poke holes
Use a fork to poke holes all over the cake, allowing the filling to seep in.
6. Prepare the poke filling
In a separate bowl, mix the sweetened condensed milk with the lemon juice. Pour this mixture over the poke holes in the cake for maximum flavor enhancement.
7. Chill the cake
Allow the cake to cool completely, then refrigerate for at least 2 hours to set the filling properly.
8. Finish with toppings
Before serving, top the cake with whipped cream, sprinkle blueberries on top, and garnish with lemon zest for a vibrant finish.
How to Store It
Fridge: Store covered for up to 5 days.
