Prep & Cook Time
- Prep Time: 10 minutes
- Cook Time: 20 minutes
- Total Time: 30 minutes
- Servings: 48 mini cupcakes
Ingredients
- 1 box white cake mix (15.25 ounces*)
- 4 large egg whites (, room temperature **)
- 1 cup buttermilk
- 1 teaspoon clear vanilla***
- ½ cup vegetable or canola oil
- ½ cup red and blue sprinkles
- White frosting
- Decorations
Instructions
- Preheat your oven to 350°F (175°C). Line mini muffin tins with paper liners.
- In a large mixing bowl, combine the dry white cake mix, egg whites, buttermilk, clear vanilla, and oil. Beat on medium speed for about 2 minutes, until the batter is smooth and well combined.
- Gently fold the red and blue sprinkles into the batter until they are evenly distributed.
- Fill each prepared mini muffin cup about ⅔ full with batter.
- Bake for 15-20 minutes, or until a toothpick inserted into the center of a cupcake comes out clean.
- Allow the cupcakes to cool in the pans for 5 minutes before transferring them to a wire rack to cool completely.
- Once completely cooled, frost the cupcakes with white frosting and add your desired patriotic decorations.
Variations
- Mini Cupcake Flag: Instead of mixing in sprinkles, bake plain cupcakes. Use white frosting to pipe stripes and add fresh blueberries and sliced strawberries to create a flag design on top.
- Layered Look: Create separate red, white, and blue layers by using a toothpick to drag red and blue food coloring into some of the white frosting before piping it onto the cupcakes.
- Ice Cream Sandwich: Slice cooled cupcakes in half horizontally, add a small scoop of vanilla ice cream, and re-sandwich for a handheld frozen treat.
- Cupcake Cones: For a fun presentation, bake the batter in flat-bottomed ice cream cones placed in a muffin tin to create edible “cones” perfect for a parade.
Tips for Success
- For best results, ensure your egg whites are at room temperature to create a lighter, fluffier cake texture.
- Use “jimmies” or “rod” style sprinkles for the mix-in, as nonpareils can bleed their color into the batter.
- Use a small cookie scoop or a tablespoon to fill the mini cupcake liners quickly and evenly for uniform baking.
Storage & Reheating
Store unfrosted cupcakes in an airtight container at room temperature for up to 2 days. Frosted cupcakes are best stored in the refrigerator for up to 3 days. These cupcakes are best served at room temperature, so remove them from the fridge 30 minutes before serving.
FAQ
Can I use whole eggs instead of just egg whites?
Yes, you can, but using only egg whites helps maintain a bright white cake color, providing a better canvas for the red and blue sprinkles.
What if I don’t have buttermilk?
You can make a quick substitute by adding 1 tablespoon of white vinegar or lemon juice to a measuring cup and filling it with milk to reach the 1-cup line. Let it sit for 5 minutes before using.
My sprinkles bled color into the batter. What happened?
This usually happens with cheaper, nonpareil-style sprinkles. For best results, use high-quality “jimmies” which hold their color better during baking.
Can I make regular-sized cupcakes instead?
Absolutely. Simply pour the batter into standard cupcake liners and bake for 18-22 minutes, or until a toothpick comes out clean. This will yield about 18-24 regular cupcakes.
What kind of decorations should I use?
You can use additional red, white, and blue sprinkles, star-shaped sprinkles, edible glitter, or small paper flags for a festive look.
Can I make the cupcakes ahead of time?
Yes, you can bake the cupcakes 1-2 days in advance. Store them unfrosted in an airtight container, then frost and decorate on the day you plan to serve them.
