Let’s Make it together
Preheat your oven: Start by preheating your oven to 350°F (175°C) and lining a muffin tin with colorful cupcake liners. This step sets the stage for your colorful creations.
Mix dry ingredients: In a bowl, whisk together all-purpose flour and baking powder until well combined. This helps distribute the leavening evenly throughout your batter.
Cream butter and sugar: In another bowl, beat softened butter and granulated sugar together until light and fluffy. This mixture should look pale and creamy, promising delicious cupcakes ahead.
Add eggs and vanilla: Beat in the eggs one at a time along with vanilla extract, ensuring each egg is fully incorporated before adding the next one. This creates a silky batter that smells heavenly.
Combine wet and dry ingredients: Slowly mix in the dry ingredients alternating with milk until just combined. Be cautious not to overmix; you want that lovely airy texture.
Divide and color: Divide your batter into separate bowls based on how many colors you want to create. Add food coloring to each bowl until you achieve vibrant shades that make you smile.
Layer in tins: Spoon dollops of each colored batter into your lined muffin tins, creating beautiful layers. Swirl gently with a toothpick if you’re feeling adventurous!
Bake away: Place them in your preheated oven and bake for 18-20 minutes or until a toothpick comes out clean from the center. The smell wafting from your kitchen will be utterly irresistible!
Cool down: Once baked, remove them from the oven and allow them to cool in the tin for about 5 minutes before transferring them to wire racks. Patience is key here!
Frost those beauties: Once cooled completely, frost generously with your favorite buttercream frosting using a piping bag for extra flair! Finish off with sprinkles or edible glitter if you’re feeling fancy.
Serve & enjoy: Present these colorful delights at any occasion or just because it’s Tuesday! Watch everyone’s faces light up as they take their first bite!
Rainbow Cupcakes are sure to bring joy wherever they go! As you savor each bite filled with nostalgia and sweetness, remember that these treats are not just desserts; they’re joyful memories waiting to happen!
