Classic Firecracker Cake is a festive red, white, and blue poke cake featuring a soft, moist white cake filled with fruity gelatin stripes and topped with fluffy whipped cream cheese frosting. This easy make-ahead dessert is perfect for Fourth of July parties, Memorial Day celebrations, and summer gatherings.

Ingredients

15.25 ounces white cake mix, 1 box, plus the ingredients called for on the package

3 ounces blue gelatin, 1 box

3 ounces red gelatin, 1 box

1½ cups boiling water, divided

8 ounces cream cheese, cold

1 cup powdered sugar

2 cups heavy whipping cream, cold

1 teaspoon vanilla extract

Red, white, and blue sprinkles, for garnish

Instructions

  1. Prepare the white cake mix according to the package directions. Pour the batter into a 9 x 13-inch baking pan and bake for approximately 20 minutes, or according to the package instructions. Allow the cake to cool completely in the pan.
  2. Using a drinking straw or the handle of a wooden spoon, poke evenly spaced holes across the cooled cake, approximately 1 inch apart.
  3. In a heatproof measuring cup or bowl, combine the blue gelatin powder with ¾ cup boiling water. Whisk until the gelatin dissolves completely.
  4. Carefully pour or pipe the dissolved blue gelatin into every other row of holes. Use a squeeze bottle or food-safe syringe for more precise filling if desired.
  5. In a separate heatproof measuring cup, combine the red gelatin powder with the remaining ¾ cup boiling water. Whisk until completely dissolved.
  6. Fill the remaining rows of holes with the red gelatin, keeping the red and blue colors separate to create distinct patriotic stripes.
  7. Cover the baking pan tightly with plastic wrap and refrigerate for at least 8 hours or overnight, allowing the gelatin to set and absorb into the cake.
  8. Chill a large mixing bowl in the refrigerator for 15 to 30 minutes. Add the cold cream cheese, powdered sugar, and vanilla extract. Beat with an electric mixer until smooth and fluffy.
  9. With the mixer running on low speed, slowly pour in the cold heavy whipping cream. Increase the mixer speed to high and beat until stiff peaks form. Avoid overmixing to maintain a thick, smooth frosting.
  10. Remove the chilled cake from the refrigerator. Spread or pipe the whipped cream cheese frosting evenly over the surface. Garnish with red, white, and blue sprinkles, then refrigerate until ready to serve. Slice into 12 portions and serve chilled.

Notes

Make ahead: Prepare the cake and add the gelatin one day before serving. Refrigerate overnight, then frost and decorate the following day.

Gelatin flavors: Use strawberry, cherry, or raspberry gelatin for the red stripes and blue raspberry gelatin for the blue stripes.

Cake variations: Substitute vanilla, lemon, or funfetti cake mix for a different flavor. White cake mix provides the clearest contrast with the colored gelatin.

Homemade cake: A homemade white or vanilla cake baked in a 9 x 13-inch pan works as an alternative to boxed cake mix.

Frosting alternative: Replace the homemade whipped cream cheese frosting with prepared whipped topping for a lighter and quicker option.

Fresh fruit garnish: Add fresh strawberries, blueberries, or raspberries for extra flavor and a festive presentation.

Prevent color mixing: Fill alternating rows carefully using a squeeze bottle or food-safe syringe to keep the red and blue gelatin separate.

Cool completely: Allow the baked cake to cool fully before adding the gelatin to prevent uneven absorption.

Fluffy frosting: Use cold cream cheese, cold heavy whipping cream, and a chilled mixing bowl. Beat until stiff peaks form without overmixing.

Chilling time: Refrigerate the gelatin-filled cake for at least 8 hours, preferably overnight, for the best texture and cleanest slices.

Storage: Store the finished cake covered in the refrigerator for up to 4 days. Keep refrigerated until ready to serve.

Freezing: Freezing is not recommended because the gelatin and whipped cream cheese frosting may change texture after thawing.

Serving: Serve the cake cold without reheating. Use a sharp knife and wipe the blade between cuts for neat slices.
