Lemon Raspberry Poke Cake

This lemon raspberry poke cake soaks up a tangy lemon-condensed milk mixture, gets topped with fluffy pudding, and stays ridiculously moist for days.

Lemon raspberry poke cake is a lemon sheet cake that’s poked full of holes and soaked in a sweetened lemon-condensed milk mixture before being topped with vanilla pudding, whipped topping, and fresh raspberries. This recipe serves 12, delivers a cold, ultra-moist slice with a tart-sweet lemon punch in every bite, and is perfect for potlucks, summer birthdays, or any gathering where you need dessert to feed a crowd. Here’s everything you need to make it perfectly.

I started making this lemon raspberry poke cake for my sister’s baby shower because I needed something I could make a day ahead. The first time I poked the holes too close together and the cake turned soggy instead of moist — about an inch apart is the sweet spot. Now it’s the dessert people ask me to bring every single summer.

Why You’ll Love This Lemon Raspberry Poke Cake

This cake is cold, tangy, and impossibly moist, with a soft pudding-and-whipped-topping layer that balances out the sharp lemon soak. It starts with a box mix, so there’s no fussy from-scratch baking involved, just a few extra steps after the cake comes out of the oven.

It’s an easy sheet cake recipe that works for kids’ parties, potlucks, or anyone who wants a make-ahead dessert that actually gets better the longer it sits. And because it has to chill for a few hours anyway, it’s one of those desserts you can genuinely finish the day before you need it.

What Ingredients Do You Need for Lemon Raspberry Poke Cake?

Cake

Ingredient	Amount	Notes
Lemon cake mix	1 box (15.25 ounces)	Plus ingredients cake mix calls for

Lemon Soak

Ingredient	Amount	Notes
Fresh lemon juice	1/2 cup	Freshly squeezed tastes brighter
Sweetened condensed milk	1 can (14 ounces)	—

Topping

Ingredient	Amount	Notes
Instant vanilla pudding mix	1 package (3.4 ounces)	—
Cold milk	2 cups	Must be cold to thicken properly
Frozen whipped topping	1 container (8 ounces)	Thawed
Fresh raspberries	1 cup	For topping
Lemon zest	Zest of 1 lemon	Optional, for garnish

The fresh lemon juice and sweetened condensed milk are what really make this a raspberry lemon cake worth repeating — that mixture is what soaks into the holes and turns a regular box cake into something tangy and dense.

Fresh raspberries do double duty here, cutting through the sweetness of the pudding layer while adding a pop of color on top. If you can’t find fresh raspberries, frozen ones work in a pinch, just pat them dry first so they don’t bleed color into the whipped topping.

How to Make Lemon Raspberry Poke Cake Step by Step

Bake the Cake

1. Preheat the oven to 350°F (175°C) and grease and flour a 9×13 inch baking pan.
2. Prepare the lemon cake mix according to the package directions, then pour the batter into the prepared pan.
3. Bake according to the package directions, or until a wooden skewer inserted in the center comes out clean.

Pro Tip: A lemon poke cake recipe only works if you poke the cake while it’s still warm, so don’t let it cool completely before this step.

4. Let the cake cool in the pan for 15-20 minutes.

Soak and Poke

5. Use the handle of a wooden spoon or a skewer to poke holes evenly over the top of the cake, about 1 inch apart.

💡 Holes that are too shallow won’t let the lemon soak reach the bottom of the cake.

6. In a small bowl, whisk together the fresh lemon juice and sweetened condensed milk.
7. Pour the lemon-condensed milk mixture evenly over the warm cake, making sure it seeps into all the holes.

Add the Topping

8. In a separate medium bowl, whisk together the instant vanilla pudding mix and 2 cups of cold milk for 2 minutes, or until thickened, then let it stand for 2 minutes.
9. Gently fold the thawed whipped topping into the pudding mixture until well combined.

Pro Tip: Fold, don’t stir — stirring too hard deflates the whipped topping and leaves you with a denser, less fluffy layer.

10. Spread the pudding and whipped topping mixture evenly over the top of the cooled cake.
11. Arrange the fresh raspberries over the top, and sprinkle with lemon zest if desired.
12. Refrigerate for at least 2 hours, or until thoroughly chilled, before serving.

Expert Tips for Perfect Lemon Raspberry Poke Cake

Pro Tips for Success

The key to an evenly soaked cake is poking the holes while the cake is still warm, since warm cake absorbs the lemon mixture far better than a cake that’s already cooled. For best results, use cold milk straight from the fridge when making the pudding — room-temperature milk won’t thicken properly in the two minutes the recipe calls for.

The most common mistake is spreading the pudding topping over a cake that’s still hot — instead, wait until the cake has fully cooled so the layers don’t slide apart. This raspberry lemon cake works best when it chills for the full two hours, since that’s what lets the lemon soak fully set into the crumb. Use fresh raspberries when you can, since their tartness and bright color hold up better than thawed frozen berries.

Delicious Variations

Quick Version: Skip the from-scratch whisking and use a store-bought whipped topping tub straight from the container if you’re short on time.

Alternative Ingredients: Swap the raspberries for sliced strawberries or blueberries for a different berry profile on the same easy sheet cake recipe.

Gluten-Free Version: Use a gluten-free lemon cake mix in place of the standard box mix, since the rest of the ingredients are naturally gluten-free.

Troubleshooting Common Problems

Problem: The cake turns out soggy instead of moist. Solution: Space the poke holes about an inch apart instead of crowding them, and make sure you’re not over-soaking with extra liquid.

Problem: The pudding layer looks runny instead of fluffy. Solution: Let the pudding mixture sit the full 2 minutes before folding in the whipped topping so it has time to set up.

How to Store and Reheat Lemon Raspberry Poke Cake

Storage Method	Duration	Best Practice
Room Temperature	Not recommended	Keep chilled due to the dairy topping
Refrigerator	3-4 days	Cover tightly with plastic wrap or a lid
Freezer	Not recommended	Whipped topping and pudding don’t freeze well

This lemon raspberry poke cake is meant to be served cold straight from the refrigerator, so there’s no reheating involved here. Just make sure it’s covered well so the cake doesn’t pick up any fridge odors or dry out at the edges. If you’ve got a few slices left over, they make a great quick dessert crumbled over vanilla ice cream instead of going to waste.
