I cracked a joke to my neighbor the first time I baked this: “It tastes like summer and childhood had a picnic and invited the whole block.” I’m serious — this Strawberry Lemonade Poke Cake somehow mashes sun-warmed strawberries, zesty lemonade, and pillowy cake into one ridiculously easy dessert. I made it on a whim for a backyard potluck, and everyone kept poking the cake (literally) to make sure it’d soak up the sweet-tart juices. The kitchen smelled like a stand at the county fair — bright lemon, sticky strawberries, and that warm, buttery cake aroma. If you love easy, nostalgic desserts that look fancy but act lazy, this one’s for you.

Why This Recipe is Awesome
This cake drinks up the strawberry-lemon mixture so every bite tastes juicy and bright — think soft cake with syrupy pockets and a fluffy whipped topping. It’s so easy even your oven can’t mess it up: box mix for speed, a simple gelatin-lemon soak for flavor, and a no-fuss topping. The texture hits all the notes: tender crumb, slightly sticky pockets of strawberry-lemon goodness, and cool creamy topping that contrasts perfectly. Who doesn’t love a dessert that looks party-ready and practically makes itself?
Ingredients
For the Main Dish:
- 1 (15.25 oz) yellow cake mix
- 3 large eggs
- 1 cup water (for the cake batter)
- 1/3 cup vegetable oil
- 1 (3 oz) package strawberry gelatin (Jell-O)
- 1/2 cup thawed frozen lemonade concentrate (about 1/2 cup)
- 1 cup boiling water
- 1/2 cup cold water
- 8 oz whipped topping (Cool Whip), thawed
- 1 cup fresh strawberries, sliced (plus extra for garnish)
- Optional: 1 tsp lemon zest for brightness
For the Sauce / Garnish (if applicable):
- Extra sliced strawberries and a little lemon zest for garnish
- Optional drizzle: 2 tbsp strawberry jam warmed with 1 tbsp water
How I Make It
Step 1:
Preheat your oven to 350°F. Grease a 9×13-inch baking pan and preheat feels like flipping on a warm welcome — don’t skip it. Whisk the cake mix, 3 eggs, 1 cup water, and 1/3 cup oil in a large bowl until smooth. Pour the batter into the pan and spread evenly; you’ll hear that soft swoosh as the spatula levels it out.
Step 2:
Bake at 350°F for about 25–30 minutes, until a toothpick in the center comes out with a few moist crumbs. Let the cake cool for 10 minutes; it should feel springy and golden with slightly darker edges. While it bakes, make the strawberry-lemon soak: dissolve the strawberry gelatin in 1 cup boiling water, stirring until clear.
Step 3:
Stir in the ½ cup thawed lemonade concentrate and ½ cup cold water. The mixture should smell like pink lemonade — sweet, tangy, and impossible to resist. Use the end of a wooden spoon or the handle of a large wooden skewer to poke holes all over the warm cake; aim for holes every inch or so. I like to press a little deeper in the center where the cake keeps the most heat.
Step 4:
Pour the strawberry-lemon liquid evenly over the cake; pour slowly so the cake absorbs it rather than pooling on top. You’ll hear tiny slurps as pockets drink up the liquid. Chill the cake in the refrigerator for at least 2 hours (longer makes it juicier). When it cools, spread the thawed whipped topping into a smooth layer and scatter the sliced strawberries across it. Add lemon zest if you want a zippy finish.
Step 5:
Garnish with a few whole strawberries or a warm strawberry jam drizzle if you’re feeling extra. Slice with a sharp knife, serve chilled, and watch people tilt their heads like they found treasure — bright, creamy, a little sticky, and totally summer-ready.
Pro Tips
- Cool the cake slightly before poking; too hot can make holes tear the crumb. Ten minutes works for me.
- Use a fork or skewer to poke deeper holes for more soak; shallower holes give you surface flavor only.
- Swirl a tablespoon of strawberry jam into the gelatin if you like extra strawberry texture.
- For firmer slices, chill overnight; for softer, more spoonable cake, serve after 2 hours.
Common Mistakes to Avoid
- Skipping preheating: Classic rookie move. It changes texture and bake time.
- Overmixing: Leads to dense or chewy results. Mix until just combined.
- Guessing cook time: Always use visual cues or a timer, not just vibes.
- Overcrowding pans: Give your food some breathing room to crisp properly.
Alternatives & Substitutions
- Use a lemon cake mix for extra citrus punch (the soak will still add strawberry flavor).
- Swap whipped topping for 1 cup whipped cream mixed with 2 tbsp powdered sugar for a fresher taste.
- Dairy-free option: use dairy-free whipped topping and a dairy-free cake mix; flavor stays lively.
- Gluten-free: use a gluten-free yellow cake mix; texture changes slightly but the soak helps keep it moist.
Variations & Tips
- Make mini poke cakes in 8-inch pans or ramekins for single-serve charm.
- Stir in 1 tsp vanilla to the batter for a warmer aroma.
- Add a handful of finely chopped basil to the strawberries for a grown-up twist.
- Turn it into bars: bake in a jelly-roll pan and cut into small squares for potlucks.
- For an adult version, replace 2 tbsp of the cold water with vodka for a boozy glaze (optional).
FAQ (Frequently Asked Questions)
- Can I make this ahead of time?
- Yes! Bake and poke the cake, pour the soak, then cover and refrigerate up to 24 hours before adding whipped topping and fresh berries. It gets juicier with time but keep the topping fresh for best texture.
- Can I double the recipe?
- Sure thing. Use two 9×13 pans or double up the pans for a party. Baking time stays the same per pan; don’t stack pans in the oven — bake separately or increase racks and rotate halfway.
- Can I substitute butter with oil?
- Technically yes, but you’ll miss that buttery magic. Use ¾ the amount of oil if a recipe calls for butter, but for this recipe the box mix already asks for oil so stick with that.
- How do I know it’s done?
- You’ll see golden edges and a springy top. A toothpick inserted in the center should come out with a few moist crumbs — not raw batter. After cooling 10 minutes, the cake should hold its shape when you poke holes.
- What if I don’t have ingredient X?
- Out of lemonade concentrate? Use ½ cup fresh lemon juice plus ¼ cup sugar, dissolved into the gelatin. No fresh strawberries? Use thawed frozen strawberries, drained and patted dry.
How I Like to Serve It
I serve this cake cold with a tall glass of iced tea or sparkling water. It shines at summer BBQs, baby showers, or anytime someone asks for “something sweet but not too heavy.” It also makes a killer picnic dessert — slice, box, and travel; the soggy baked-goods fear doesn’t apply here. In winter, I add a sprinkle of cinnamon to the whipped topping for warmth.
Notes
- Store covered in the fridge for up to 3 days. The whipped topping may weep slightly — just give it a gentle stir before serving.
- Make sure any meat in other dishes reaches safe temps; for reference cook chicken to 165°F.
