Vanilla Rainbow Muffin

Preheat oven to 375 F. Grease a 12-count muffin tin or line with muffin liners.

In a large bowl, sift flour, baking powder, baking soda and salt. Mix well and set aside.

In the bowl of an electric mixer fitted with the paddle attachment, cream butter on medium-high speed, until light and fluffy. Gradually add sugar and continue to beat until well combined and fluffy. Reduce the mixer speed to medium and slowly add eggs until just blended.

With the mixer on low, slowly add half the flour mixture; mix until just blended. Add the milk and vanilla extract, mix until just blended. Slowly add remaining flour mixture, scraping down sides of the bowl with a spatula as necessary, until just blended.

Divide batter evenly into several small bowls, depending on how many colors you want.

Add food coloring paste to each bowl and mix thoroughly.

Working with one color of batter at a time, evenly distribute batter among prepared muffin liners. Layer with remaining color batters.

Bake for 20 to 25 minutes. Transfer muffin tin to a wire rack and let cupcakes cool completely.
