• Sift all-purpose flour, baking powder, and salt in a bowl and mix.
• Use a smaller bowl to create a well in the flour mixture. (This prevents you from having to use multiple bowls for your wet and dry ingredients.)
• Add eggs, sugar, milk, and oil, and vanilla. Mix all ingredients together with a hand mixer until well-combined.
• Add lemon extract into batter and mix until combined.
• Divide batter equally into 4 bowls (about 1 cup eacand add the gel food coloring to each bowl. I used pink, purple, orange, and blue.
• Line a muffin tin with cupcake liners.
• Add about 1-2 tablespoons of each color batter to the cupcake tins at a time. Do not mix the batter to keep the layered rainbow effect when baking!
• Leave about ¾ of an inch of room in the cupcake tins to avoid overflow when baking.
• Bake cupcakes at 350 degrees for 15-20 minutes.
• Allow cupcakes to cool for about an hour before icing.

Frosting:

• Mix together softened butter, powdered sugar, vanilla extract and milk. MIx with a hand mixer until fully creamed together.
• Use a pastry bag to pipe frosting onto cooled cupcakes.
• Sprinkle cupcakes with rainbow sprinkles.
• Serve and enjoy!
