For the Cake

3 packages Pop Rocks candy
Black licorice ropes
White frosting (less than 1/4 cup)

How to Make Firecracker Cupcakes

Step 1: Preheat the Oven

Heat oven to 350 degrees Fahrenheit.

Step 2: Prepare Red Velvet Batter

Make 8 ounces (1/2 box) of red velvet cake batter according to box directions.
Add 1/2 cup sour cream before mixing. Be sure to use HALF of the ingredient amounts called for on the box!
Set bowl aside.

Step 3: Prepare White Cake Batter

Make white cake batter according to directions on box.
Add 1/2 cup sour cream before mixing.
Split batter into two equal amounts; add blue food coloring to one portion until bright blue.

Step 4: Bake the Cakes

Coat three 9-inch cake pans with cooking spray and lightly flour the bottoms.
Add the three batters to the pans and bake at 350 degrees for 18-23 minutes.
Check doneness by inserting a toothpick into the center; it should come out clean.

Step 5: Cool Cakes

Allow cakes to cool in pans on wire racks, then turn out from pans onto a cutting board.

Step 6: Cut Circles from Cakes

Using a 1.5 inch round cookie cutter, cut circles from each baked cake. You should get about 8 circles from each cake.

Step 7: Hollow Out Centers

Using a jumbo straw or an apple corer, remove the center from each of the cake circles. Save the centers from red and blue cupcakes as you’ll need them later.

Step 8: Stack Your Cakes

Pipe a line of frosting around the top edge of the red and white cake circles. Stack white cakes on top of blue cakes and red cakes on top of white cakes.

Step 9: Fill with Pop Rocks

Add Pop Rocks down the hollow centers of the stacked cakes. Replace a portion of the red cake plugs back into tops, covering centers filled with Pop Rocks.

Step 10: Final Garnish

Use kitchen scissors to cut licorice rope pieces approximately 1-1/2 inches long and insert them into centers of red cakes.

Now you’re ready to serve these delightful Firecracker Cupcakes! Enjoy their sweet taste and festive nature at your next celebration!

Use fresh ingredients: Ensure your baking ingredients like eggs and sour cream are fresh for the best flavor and texture.
Don’t overmix: Mix your batter just until combined; overmixing can lead to dense cupcakes.
Proper cooling: Allow your cakes to cool completely before cutting and filling to maintain structural integrity.
Adjust food coloring: Start with a small amount of blue food coloring; you can always add more if needed to reach your desired shade.
Seal well: Make sure to plug any openings tightly after filling with Pop Rocks so they don’t spill out when serving.
Experiment with flavors: Try different cake mix combinations or frosting flavors to customize your firecracker cupcakes further.

Common Mistakes to Avoid

When making Firecracker Cupcakes, it’s easy to overlook some key details. Here are common mistakes to steer clear of:

Skipping the sour cream: Not adding sour cream can lead to dry cupcakes. Always include it for moisture.

Ignoring baking times: Each oven varies, so check for doneness a few minutes before the recommended time to avoid overbaking.
Not cooling properly: Allowing the cakes to cool completely is crucial. Skipping this step can cause frosting to melt and make a mess.
Forgetting the Pop Rocks: These candies are essential for the fun explosion! Make sure to add them right before serving for maximum fizz.
