Ingredients List

Here’s what you’ll need to make your own flag cake:

• 1 box white cake mix
• Eggs, oil, and water (as specified on the cake mix box)
• 1 package (3 oz) strawberry Jello
• 1 cup boiling water
• 1/2 cup cold water
• 1 tub whipped topping (like Cool Whip or homemade)
• 1 pint fresh strawberries, sliced
• 1/2 pint fresh blueberries

Optional substitutions:

• Use a gluten-free white cake mix for a celiac-friendly version.
• Opt for coconut whipped topping if dairy-free.
• Blueberries can be swapped for blackberries; raspberries for strawberries if desired.

Instructions

This Jello poke cake comes together in just a few easy steps. Let’s break it down:

Bake the Cake

• Preheat oven to 350°F (or as directed on your cake mix).
• Prepare the white cake mix according to the box instructions.
• Pour batter into a greased 9×13 inch baking dish and bake until a toothpick comes out clean (about 25–30 minutes).
• Allow the cake to cool for 15–20 minutes.

Make the Jello Mixture

• In a mixing bowl, combine strawberry Jello with 1 cup boiling water. Stir until dissolved.
• Add 1/2 cup cold water and mix well.

Poke the Cake

• Using a fork, skewer, or wooden spoon handle, poke holes all over the cake—spacing them about 1 inch apart.

Pour the Jello

• Slowly pour the Jello mixture evenly over the entire cake. It should seep into the holes, creating a vibrant marbled effect.

E. Chill the Cake

• Cover the cake and refrigerate for at least 3 hours, preferably overnight. This ensures the Jello sets and flavors infuse.

Decorate the Cake

• Once chilled, spread whipped topping evenly over the surface.
• In the top-left corner, place a square of blueberries to represent the “stars.”
• Use sliced strawberries to create red “stripes” across the rest of the cake.
• The white whipped topping acts as your white stripes—voilà, you’ve got a delicious stars and stripes dessert!

Tips and Substitutions

Here are a few handy tricks to make this recipe your own:

• Try raspberry or cherry Jello if you prefer a different flavor.
• Want more tang? Use lemon cake mix for a zesty twist.
• Homemade whipped cream works too—just stabilize it with gelatin or cornstarch.
• Store covered in the fridge for up to 3 days—the flavors only get better!
• Planning a party? This is the best flag cake for July 4th because it’s make-ahead friendly and crowd-approved.
