Ingredients You’ll Need
Getting the ingredients together for the Blueberry Lemon Poke Cake Recipe is refreshingly straightforward. Each component plays an important role—from the tangy lemon cake base to the juicy blueberries that add color and texture, all the way to the luscious lemon curd and whipped topping that provide creamy indulgence.
- 1 box lemon cake mix: The foundation of this cake, it offers a convenient and delicious lemon-flavored base.
- Water, eggs, and oil: Usually called for on the box, these combine to create the perfect batter texture.
- 1½ cups blueberries (fresh or frozen): These add bursts of natural sweetness and a lovely pop of color.
- 1 large lemon (zest and juice): Use about 1 teaspoon zest and 1 tablespoon juice to infuse bright, authentic lemon flavor.
- ¼ cup sugar: Balances the tartness while helping to create the blueberry sauce.
- 2 tsp cornstarch: Thickens the blueberry sauce so it seeps perfectly into the cake.
- ½ tsp vanilla extract: Enhances the overall flavor with a hint of warmth.
- ½ cup jarred lemon curd: The creamy, tangy highlight that gets poked into the cake to keep it moist and flavorful.
- 1 8 oz. container whipped topping (Cool Whip): Adds a cloud-like finishing touch that’s light and creamy.
How to Make Blueberry Lemon Poke Cake Recipe
Step 1: Prepare and Bake the Cake
Start by preparing the lemon cake mix according to the instructions on the box, using the required water, eggs, and oil. Pour the batter into a greased baking dish, smoothing the top evenly. Bake as directed until the cake springs back lightly when touched and a toothpick inserted comes out clean. Let the cake cool slightly so it’s ready for the next step.
Step 2: Make the Blueberry Sauce
While your cake is baking, combine the blueberries, lemon zest, lemon juice, sugar, cornstarch, and vanilla extract in a small saucepan. Cook over medium heat, stirring frequently until the mixture thickens and the blueberries have softened to create a syrupy sauce. This sauce is the heart of the poke cake’s moist, flavorful pockets.
Step 3: Poke the Cake and Add Fillings
Once the cake is cool enough to handle, use the back of a spoon or a fork to poke holes evenly all over the surface—big enough for the lemon curd and blueberry sauce to sink into. Spoon the lemon curd into each hole, then drizzle the warm blueberry sauce over the cake, allowing it to settle into every crevice.
Step 4: Chill and Top
Refrigerate the cake for at least two hours to let all the luscious flavors meld together and for the cake to soak up the fillings. When ready to serve, spread the whipped topping generously on the cake’s surface for that perfect creamy contrast against the bright lemon and juicy blueberries.
How to Serve Blueberry Lemon Poke Cake Recipe

Garnishes
Enhance the presentation and flavor by garnishing your Blueberry Lemon Poke Cake Recipe with fresh lemon slices, extra blueberries, or a sprinkle of lemon zest on top of the whipped topping. These simple touches not only make the cake look stunning but reinforce its fresh, citrusy character.
Side Dishes
This cake pairs beautifully with a light cup of tea, a scoop of vanilla ice cream, or a dollop of fresh cream. The delicate sweetness and tanginess make it a perfect companion to balance richer or creamier sides without overpowering the palate.
Creative Ways to Present
For a party or special occasion, try serving the Blueberry Lemon Poke Cake Recipe in individual glass parfait cups layered with the remaining blueberry sauce and whipped topping. This adds a charming twist to presentation, making each serving feel personalized and extra special.
Make Ahead and Storage
Storing Leftovers
Store any leftover Blueberry Lemon Poke Cake Recipe in an airtight container in the refrigerator. It will stay fresh and moist for about 3 to 4 days, allowing you to enjoy the delightful flavors for several days after baking.
Freezing
If you want to freeze the cake, it’s best to wrap it well with plastic wrap and then foil before placing it in the freezer. It can keep for up to 2 months this way. Thaw it overnight in the refrigerator before serving, and add fresh whipped topping if needed.
Reheating
This cake is generally best served chilled, but if you prefer a slightly warmed slice, pop it in the microwave for about 15 seconds on low heat. Avoid overheating to preserve the texture and keep the whipped topping cool and fluffy.
FAQs
Can I use frozen blueberries for this cake?
Absolutely! Frozen blueberries work wonderfully in the Blueberry Lemon Poke Cake Recipe. Just make sure to thaw them slightly and drain any excess liquid before cooking the sauce to prevent it from becoming too watery.
Is lemon curd necessary for this recipe?
While lemon curd adds a beautiful tangy creaminess that really elevates the poke cake, you can substitute it with lemon jam or a thick lemon glaze if lemon curd is not available.
Can I make this cake gluten-free?
To make the Blueberry Lemon Poke Cake Recipe gluten-free, simply choose a gluten-free lemon cake mix and ensure all other ingredients like the whipped topping and lemon curd do not contain gluten. The rest of the process stays exactly the same.
How long should I chill the cake after poking and filling?
For the best results, chill the cake for at least two hours, though overnight chilling will deepen the flavors even more and give the cake a wonderfully moist texture.
Can I make this recipe dairy-free?
Yes! Look for dairy-free whipped toppings and lemon curd, or make your own versions. Also, double-check the cake mix for dairy ingredients to keep it suitable for dairy-free diets.

Instructions
- Prepare the Cake Batter: Preheat your oven as per the lemon cake mix box instructions. Prepare the lemon cake batter according to the package directions using the required water, eggs, and oil.
- Bake the Cake: Pour the batter into a greased 9×13-inch baking pan. Bake the cake for approximately 40 minutes or until a toothpick inserted in the center comes out clean.
- Make the Blueberry Filling: While the cake bakes, combine the blueberries, sugar, lemon juice, and corn starch in a small saucepan over medium heat. Cook, stirring frequently until the mixture thickens and the blueberries have softened, about 5-7 minutes. Remove from heat and stir in the lemon zest and vanilla extract. Allow to cool slightly.

Notes
- If using frozen blueberries, do not thaw before cooking the filling; cooking directly from frozen works best.
- Adjust sugar in the blueberry filling based on the sweetness of your berries.
- For a brighter lemon flavor, zest the lemon before juicing.
- Ensure to poke holes immediately after baking while the cake is still warm for best absorption.
- Store leftovers covered in the refrigerator for up to 3 days.
