Essential Ingredients
An Easy Strawberry Jello Flag Cake needs simple ingredients for a 9×13-inch pan (serves 12-16). Here’s what you’ll need:
- Cake Base:
- 16.5 oz vanilla cake mix
- 1 cup water
- 3 large eggs
- ⅓ cup canola oil
- Why it matters: The vanilla cake mix creates a light, fluffy base that absorbs the Jello for extra flavor.
- Substitutions: Use a white or yellow cake mix. For homemade, mix 3 cups flour, 2 tsp baking powder, ½ tsp salt, 1 cup butter, 2 cups sugar, 3 eggs, 1 cup milk, 1 tsp vanilla. Use vegetable oil or melted butter for canola oil.
- Jello Layer:
- 3 oz strawberry Jello mix
- 1 cup boiling water
- ½ cup cold water
- Why it matters: Strawberry Jello adds a sweet, red soak that enhances flavor and the patriotic theme.
- Substitutions: Use raspberry or cherry Jello for a similar red color. Sugar-free Jello works for a lighter option.
- Topping and Decoration:
- 8 oz whipped cream (store-bought or homemade)
- 1 pint blueberries
- 1 ½ quarts strawberries
- Why it matters: Whipped cream creates a white “flag” background, while blueberries and strawberries form the blue field and red stripes.
- Substitutions: Use Cool Whip or make whipped cream (2 cups heavy cream, ¼ cup powdered sugar, 1 tsp vanilla). Swap blueberries for blackberries, strawberries for raspberries or sliced cherries.
Tip: Use fresh, ripe berries for vibrant colors and flavor. Pat berries dry to prevent excess moisture. Choose a reliable cake mix brand for consistent results.
Step-by-Step Instructions
Let’s make this Easy Strawberry Jello Flag Cake with these easy steps. Follow along with tips to make it perfect!
Step 1: Prep the Ingredients
- Wash 1 pint blueberries and 1 ½ quarts strawberries under cold water. Pat dry thoroughly with paper towels.
- Hull strawberries by removing green tops with a small knife or huller, then slice lengthwise into thin pieces.
- Tip: Dry berries well to keep the cake neat. Slice strawberries evenly for uniform stripes.
Step 2: Bake the Cake
- Preheat the oven to the temperature specified on the cake mix box (usually 350°F/175°C).
- Grease a 9×13-inch baking pan with baking spray or butter and flour.
- In a large bowl, combine 16.5 oz vanilla cake mix, 1 cup water, 3 eggs, and ⅓ cup canola oil. Mix according to package directions (usually 2 minutes with a hand mixer).
- Pour batter into the prepared pan and bake as directed (typically 25-35 minutes) until a toothpick inserted in the center comes out clean.
- Cool the cake in the pan for 15-20 minutes.
- Tip: Follow box timing closely to avoid overbaking. Use a glass or metal pan for even baking.
Step 3: Prepare the Jello
- In a medium bowl, dissolve 3 oz strawberry Jello mix in 1 cup boiling water, stirring until fully dissolved (about 2 minutes).
- Add ½ cup cold water and mix well.
- Tip: Stir thoroughly to avoid grainy texture. Let Jello cool slightly (but not set) before pouring.
Step 4: Poke and Soak the Cake
- Using the tines of a fork, poke holes all over the top of the cooled cake, about 1 inch apart, going halfway through.
- Slowly pour the Jello mixture evenly over the cake, ensuring it seeps into the holes.
- Allow the cake to finish cooling completely at room temperature (about 30 minutes).
- Tip: Pour Jello gradually to fill holes evenly. Use a fork for smaller, more uniform holes.
Step 5: Add Whipped Cream
- Spread 8 oz whipped cream evenly over the cooled cake using a spatula.
- Tip: For homemade whipped cream, beat 2 cups chilled heavy cream with ¼ cup powdered sugar and 1 tsp vanilla until stiff peaks form. Spread smoothly for a clean flag base.
Step 6: Decorate the Flag
- In the top left corner of the cake, arrange 5 or more rows of blueberries to form the blue star field (about a 4×5-inch rectangle).
- Arrange sliced strawberries in 4 horizontal rows across the remaining cake to create red stripes, leaving white whipped cream visible between rows as white stripes.
- Tip: Place berries tightly to mimic flag stripes. Adjust rows based on pan size for a balanced look.
Step 7: Chill and Serve
- Cover the cake with plastic wrap or a lid and chill in the fridge for 3-4 hours to set the Jello and flavors.
- Slice into squares and serve chilled for a refreshing treat.
- Tip: Wipe the knife between cuts for neat slices. Serve on patriotic plates with extra berries on the side for flair.

FAQs
Q: Can I use homemade whipped cream instead of store-bought?
- A: Yes! Beat 2 cups chilled heavy cream with ¼ cup powdered sugar and 1 tsp vanilla for a fresher topping. Store-bought (like Cool Whip) saves time.
Q: What are the health benefits of this cake?
- A: Strawberries and blueberries are rich in vitamins C and K, fiber, and antioxidants. Use sugar-free Jello or less whipped cream for a lighter option. Enjoy in moderation!
Q: How do I keep Jello from pooling in one spot?
- A: Poke holes evenly and pour Jello slowly over the cake. Tilt the pan slightly to distribute if needed.
Q: Can kids help make this recipe?
- A: Totally! Kids can poke holes, pour Jello, spread whipped cream, or arrange berries. Supervise baking and boiling water for safety.
Q: Can I use frozen berries?
- A: Fresh berries are best for texture and appearance. Frozen (thawed and drained well) may work but can bleed juice and soften the design.
Q: What if my cake sticks to the pan?
- A: Grease thoroughly with spray or butter and flour. Cool for 15-20 minutes before poking to ease release.
