I baked up some of Martha's yellow cupcakes:
Ingredients
1 1/2 cups all-purpose flour (spooned and leveled)
1 1/2 teaspoons baking powder
1/2 teaspoon salt
1/2 cup milk
1 teaspoon pure vanilla extract
1/2 cup (1 stick) unsalted butter, room temperature
3/4 cup sugar
2 large eggs
Sprinkles, for decorating
1/2 teaspoon salt
1/2 cup milk
1 teaspoon pure vanilla extract
1/2 cup (1 stick) unsalted butter, room temperature
3/4 cup sugar
2 large eggs
Sprinkles, for decorating
Directions
Preheat oven to 350 degrees; line the cups of a standard
(12-cup) muffin tin with paper or foil liners. In a small bowl, whisk
together flour, baking powder, and salt; set aside. In a
liquid-measuring cup, mix milk and vanilla; set aside.
In a large bowl, with an electric mixer, beat butter and
sugar until light and fluffy, 3 to 4 minutes. Add eggs one at a time,
beating well after each addition. With mixer on low speed, add half of
dry ingredients, followed by milk-vanilla mixture, then remaining dry
ingredients. Do not overmix.
Divide batter evenly among prepared muffin cups (a 2-ounce or 1/4-cup ice-cream scoop is good for this).
Place tin on a rimmed baking sheet; bake until a toothpick
inserted in center of a cupcake comes out clean, 20 to 25 minutes. Cool
cupcakes 5 minutes in tin, then remove and cool completely on a rack
before frosting.
For the frosting, I used my own recipe:
Ingredients
2 sticks unsalted butter
4 cups confectioners sugar, sifted
1 teaspoon vanilla extract
2 tablespoons milk
Directions
Beat butter, confectioners sugar, vanilla extract, and milk.
Add desired amount of food coloring to frosting.
