Cuisine: American
Serves: 12 cupcakes
Ingredients
- 1 1/2 cups all-purpose flour
- 1 cup granulated sugar
- 1/2 cup unsalted butter, softened
- 2 large eggs
- 1/2 cup milk
- 1 tablespoon vanilla extract
- 1 tablespoon baking powder
- 1/4 teaspoon salt
- 1/2 cup rainbow sprinkles
- 1 cup butter, softened (for frosting)
- 4 cups powdered sugar (for frosting)
- 1/4 cup heavy cream (for frosting)
- Food coloring (for frosting)
Instructions
- Preheat the oven to 350°F (175°C) and line a 12-cup muffin tin with cupcake liners.
- In a medium bowl, whisk together all-purpose flour, baking powder, and salt until well combined and set aside.
- In a large mixing bowl, cream softened butter and granulated sugar together using an electric mixer until light and fluffy, approximately 3-4 minutes.
- Add eggs one at a time to the butter mixture, beating well after each addition. Mix in vanilla extract.
- Gradually add the dry flour mixture to the wet ingredients, alternating with milk, mixing on low speed until just combined.
- Gently fold rainbow sprinkles into the batter, being careful not to overmix.
- Divide batter evenly among cupcake liners, filling each about 2/3 full.
- Bake in preheated oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
- Remove cupcakes from oven and allow to cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
- For frosting, beat softened butter in a large bowl until creamy and smooth.
- Gradually add powdered sugar, mixing on low speed. Pour in heavy cream and continue mixing until frosting is light and fluffy.
- Divide frosting into separate bowls and add different food coloring to create a rainbow effect.
- Using a piping bag with a star tip, pipe frosting onto cooled cupcakes in a swirling motion to create rainbow effect.
- Garnish with additional rainbow sprinkles if desired.
Tips
- Room Temperature Ingredients: Make sure your butter, eggs, and milk are at room temperature for a smoother batter and better rise.
- Don’t Overmix: When folding in the rainbow sprinkles, be gentle! Overmixing can deflate the batter and make your cupcakes dense.
- Perfectly Baked: Keep an eye on your cupcakes while they bake. Start checking for doneness at 18 minutes by inserting a toothpick in the center—if it comes out clean, they’re ready!
- Chill Your Frosting: If your frosting is too soft to pipe, pop it in the fridge for a few minutes to firm it up before decorating.
- Coloring the Frosting: For a vibrant rainbow effect, use gel food coloring instead of liquid food coloring, as it won’t affect the consistency of your frosting.
- Piping Technique: Use a piping bag fitted with a star tip for beautiful swirls. Start from the outside and work your way in for a stunning finish!
- Storage: Store your cupcakes in an airtight container at room temperature for up to 3 days, or freeze them for longer storage.Enjoy creating these delightful treats that are as fun to make as they are to eat!
