Introduction

This Blueberry Lemon Poke Cake is a delightful combination of tangy and sweet flavors, perfect for spring or summer gatherings. Moist yellow cake is infused with a fresh blueberry lemon sauce, then topped with whipped cream and extra blueberries for a fresh finish.

A slice of yellow cake with a purple blueberry filling dripping slightly onto a white plate is shown in the foreground. The cake has three layers: a thick bottom layer of yellow cake with embedded blueberries, a middle layer of rich purple blueberry filling, and a top layer of white cream frosting topped with fresh blueberries. Behind the slice, there is a full cake on a silver stand with the same layers and blueberry topping visible. A silver fork rests on the edge of the plate next to the cake slice. A blue and white striped cloth is partially visible on the side, and two lemons, one whole and one halved, sit on the white marbled surface in the background.

Ingredients

1 box yellow cake mix
3 large eggs
1 cup water
1/2 cup vegetable oil
1 cup fresh blueberries (or frozen)
1/2 cup lemon juice (freshly squeezed)
1/2 cup granulated sugar
1 cup whipped cream (for serving)
1 cup blueberries (for garnish)
1 tablespoon lemon zest

Instructions

Step 1: Preheat the oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan.
Step 2: In a mixing bowl, combine the yellow cake mix, eggs, water, and vegetable oil. Mix until smooth.
Step 3: Pour the batter into the prepared baking pan and bake for 30 minutes or until a toothpick inserted in the center comes out clean.
Step 4: While the cake bakes, prepare the blueberry lemon sauce. In a saucepan over medium heat, combine the blueberries, lemon juice, and sugar. Cook until the blueberries burst and the mixture thickens, about 5-7 minutes.
Step 5: Remove the sauce from heat and let it cool slightly.
Step 6: When the cake is done, remove it from the oven and let it cool for 10 minutes.
Step 7: Using a toothpick, poke holes all over the top of the cake.
Step 8: Pour the blueberry lemon sauce evenly over the cake, allowing it to seep into the holes.
Step 9: Let the cake cool completely before topping with whipped cream, additional blueberries, and lemon zest.

Tips & Variations

Use frozen blueberries if fresh are not available; just thaw them before making the sauce.
For extra zest, add a teaspoon of lemon zest to the cake batter before baking.
Try substituting whipped cream with cream cheese frosting for a richer dessert.
Serve chilled for a refreshing treat on warm days.

Storage

Store the cake in an airtight container in the refrigerator for up to 3 days. Reheat slightly or serve chilled based on preference. The whipped cream topping is best added fresh before serving to keep it light and fluffy.
