Lemon-Blueberry Poke Cake Ingredients
For the Cake
• Cooking Spray – Prevents sticking during baking; consider using parchment paper for added assurance.
• Vanilla Cake Mix (13.25-oz. box) – Provides structure and flavor as the cake base; homemade vanilla cake can elevate the dish further.
• Fresh or Frozen Blueberries (2 1/2 cups) – Adds natural sweetness and texture; frozen blueberries may release more juice while cooking.
• Juice of 1/2 Lemon – Introduces acidity and brightness to the sauce and frosting; adjust according to taste preferences.
For the Blueberry Sauce
• Granulated Sugar (1 Tbsp.) – Balances the tartness of lemon in the sauce; use more or less depending on your sweetness preference.
For the Frosting
• Store-bought Whipped Topping (1/2 cup) – Offers lightness and creaminess; homemade whipped cream is a delicious alternative.
• Cream Cheese (2 x 8-oz. pkg., softened) – Essential for rich frosting; soften it beforehand for smooth mixing.
• Unsalted Butter (1 cup, 2 sticks, softened) – Enhances the texture and flavor of the frosting.
• Confectioners’ Sugar (2 1/4 cups, 260 g.) – Sweetens the frosting and provides structure without graininess.
• Lemon Zest (zest of 1 lemon + more for serving) – Elevates the lemon flavor; use a microplane for a fine zest.
• Vanilla Extract (1 tsp.) – Adds depth of flavor in the frosting.
For Garnish
• Fresh Blueberries – These not only make for aesthetic appeal but also enhance the blueberry flavor in the Lemon-Blueberry Poke Cake!
How to Make Lemon-Blueberry Poke Cake
Prepare the Cake: Preheat your oven to 350°F (175°C) and generously grease a 13×9-inch baking dish with cooking spray. Mix the vanilla cake according to the package directions, incorporating the juice and zest of half a lemon. Bake for 25-30 minutes, or until a toothpick inserted comes out clean.
Make Blueberry Sauce: In a medium saucepan, combine the blueberries, granulated sugar, and lemon juice. Cook over medium heat, mashing some blueberries as they cook, until the mixture thickens. Set it aside to cool completely.
Poke the Cake: Allow the cake to cool in the pan for about 10-15 minutes. Using the handle of a wooden spoon, poke holes all over the surface of the cake to create pockets for the delicious sauce.
Soak Cake: Pour the cooled blueberry sauce evenly over the poked cake, ensuring the sauce seeps into the holes. Let the cake absorb the sauce for at least 30 minutes for optimal flavor infusion.
Prepare Frosting: In a large mixing bowl, beat together the softened cream cheese and butter until creamy and smooth. Gradually add the confectioners’ sugar, lemon zest, lemon juice, and vanilla extract, mixing until you achieve a light and fluffy frosting.
Frost the Cake: Once the cake has absorbed the sauce, spread an even layer of the cream cheese frosting over the top. Garnish with fresh blueberries and additional lemon zest for a beautiful presentation.
Chill and Serve: Refrigerate the cake for a few hours to allow the flavors to meld beautifully or serve immediately if you can’t wait! Store any leftovers in an airtight container in the fridge.
Optional: Serve chilled with a dollop of whipped topping for extra creaminess.

Make Ahead Options
These Lemon-Blueberry Poke Cakes are perfect for meal prep enthusiasts! You can bake the cake up to 24 hours in advance, allow it to cool, then poke holes and pour the blueberry sauce over it. Simply cover it tightly and refrigerate it. The blueberry sauce can also be prepared a day ahead so it has time to thicken.

This way, you not only save time but also ensure that each bite remains just as delicious and moist—a fantastic strategy for busy weeknights!
Expert Tips for Lemon-Blueberry Poke Cake
• Use Fresh Ingredients: Opt for fresh lemons and blueberries to enhance flavor. If using frozen blueberries, thaw them beforehand to avoid excess moisture.
• Poking Technique: Use a sturdy handle—like that of a wooden spoon—to create evenly spaced holes. This ensures maximum absorption of the flavorful blueberry sauce throughout the Lemon-Blueberry Poke Cake.
• Cooling Time is Key: Allowing the cake to cool adequately before pouring the sauce prevents steaming and helps the sauce seep in better. A cooled cake will maintain its structure and moisture.
• Frosting Consistency: Ensure your cream cheese and butter are at room temperature for easy mixing. Cold ingredients can lead to a lumpy frosting.
• Storage Tips: Store leftover cake in an airtight container in the refrigerator for up to 3-4 days. This helps maintain its moisture and flavors, ensuring every bite is delicious!
