How to Make It

Follow these simple steps to create your Blueberry Lemon Poke Cake:

Preheat the Oven

Preheat your oven to 350°F. Line a 9 x 13-inch baking pan with parchment paper and lightly coat with cooking spray.

Bake the Cake

Prepare and bake the vanilla cake according to the package directions. Let the cake cool completely in the pan.

Make the Blueberry Filling

In a small saucepan over medium heat, combine the blueberries, lemon juice, and granulated sugar. Cook, stirring occasionally, until the berries burst and the mixture thickens to a jam-like consistency, about 5 to 7 minutes. Remove from heat and let the mixture cool for about 15 minutes.

Combine Blueberry Filling and Topping

Gently fold the whipped topping into the cooled blueberry mixture until smooth and evenly combined.

Prepare the Frosting

In a large bowl, beat the softened butter and cream cheese together until creamy and well blended. Add the powdered sugar, lemon zest, lemon juice, and vanilla extract. Beat until fluffy and smooth, scraping down the sides as needed.

Poke Holes in the Cake

Using the handle of a wooden spoon, poke holes all over the cooled cake, spacing them evenly.

Add Blueberry Mixture

Pour the blueberry mixture over the cake, spreading it so it fills the holes and covers the surface.

Frost the Cake

Spread the cream cheese frosting evenly over the top. Garnish with fresh blueberries. Chill for at least 1 hour before slicing and serving.

How to Store It

Fridge: Store in an airtight container for up to 3 days.
Freezer: No, the frosting doesn’t freeze well.
Reheat: Not recommended; best served chilled.

Tips for Best Results

• Allow the cake to cool completely before poking holes.
