Blueberry Lemon Poke Cake Ingredients
For the Cake

- 3 large eggs – Eggs add richness and help bind the ingredients together for a perfect rise.

- 1/3 cup vegetable oil – This adds moisture and keeps the cake tender without making it greasy.
For the Poke Mixture
- 1 cup blueberry syrup (store-bought or homemade) – This infuses the cake with sweet blueberry flavor, making every bite a delight.
- 2 tablespoons fresh lemon juice – Fresh lemon juice brightens up the flavors, balancing out the sweetness of the syrup.
For the Topping
- 1 cup heavy whipping cream (chilled) – Chilled cream whips up beautifully for a light and airy topping.
- 1/4 cup powdered sugar – Powdered sugar helps sweeten the whipped cream while maintaining its smooth texture.
- 1 teaspoon vanilla extract – Vanilla adds depth of flavor to your whipped cream, enhancing its overall taste.

Step-by-Step Blueberry Lemon Poke Cake
1. Preheat the oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan to ensure your cake releases perfectly after baking.
2. Combine the yellow cake mix, eggs, water, and vegetable oil in a mixing bowl. Mix until well combined, creating a smooth batter that will rise beautifully in the oven.
3. Pour the batter into the prepared baking pan and smooth the top with a spatula. This will help your cake bake evenly, ensuring every bite is deliciously moist.
4. Bake for 30 minutes or until a toothpick inserted in the center comes out clean. The top should be golden brown and slightly springy to the touch.
5. Cool for 10 minutes after removing from the oven. This short resting period allows for easier handling while you prepare to poke holes into your warm cake.
Poke the Cake:
6. Poke holes all over the top of the cake using a toothpick while it’s still warm. This step lets all that delightful blueberry syrup soak deeply into the cake.
7. Mix together 1 cup of blueberry syrup and 2 tablespoons of fresh lemon juice in a small bowl. Pour this tangy mixture evenly over the cake, allowing it to soak in for maximum flavor.
Prepare the Topping:
8. Whip the heavy cream in a mixing bowl until soft peaks form. Gradually add in 1/4 cup of powdered sugar and 1 teaspoon of vanilla extract, whipping until stiff peaks form for that perfect fluffy topping.
9. Spread the whipped cream generously over the top of your soaked cake. Garnish with fresh blueberries and sprinkle some lemon zest on top for an extra zesty finish!
Serve:
10. Chill in the refrigerator for at least 1 hour before serving. Slice into squares and enjoy every bite of this refreshing Blueberry Lemon Poke Cake!
