Ingredients

8 tablespoons (1 stick) unsalted butter, room temperature, plus more for pan 

1 3/4 cups all-purpose flour (spooned and leveled), plus more for pan 

2 teaspoons baking powder 

1/2 teaspoon salt 

3/4 cup sugar 

2 large eggs, room temperature 

1 teaspoon pure vanilla extract 

1/2 cup whole milk 

8 tablespoons (1 stick) room-temperature unsalted butter 

1 1/2 cup confectioners' sugar 

1/2 teaspoon pure vanilla extract 

3-4 teaspoons seedless raspberry jam 

4 ounces bittersweet chocolate 

Tip-Top toppings (optional) 

Preparation

Preheat oven to 350 degrees. Butter and flour a standard 12-cup muffin pan, or use paper liners. In a medium bowl, whisk together flour, baking powder, and salt; set aside.

With an electric mixer, beat butter and sugar until light and fluffy. Add eggs one at a time, beating well after each addition; add vanilla, and mix until combined. On low speed, beat in half the flour mixture, followed by milk; end with remaining flour mixture. Mix just until incorporated (do not overmix).

Divide batter among prepared muffin cups, filling each 2/3 full. Bake until a toothpick inserted in center of a cupcake comes out clean, 22 to 24 minutes. Cool cupcakes in pan, 5 minutes; transfer to a wire rack to cool completely. Frost with your choice of buttercream.

VANILLA BUTTERCREAM: With an electric mixer, beat butter until light and fluffy. On medium speed, beat in confectioners’ sugar, 1/2 cup at a time, beating well after each addition and scraping down bowl as necessary. Mix in vanilla. Increase speed to high, and beat until light and fluffy, about 5 minutes. Makes 1 1/2 cups.

RASPBERRY BUTTERCREAM: Make Vanilla Buttercream, then beat in jam.

CHOCOLATE BUTTERCREAM: Place chocolate in a large heatproof bowl set over (not in) a saucepan of simmering water. Heat, stirring occasionally, until smooth, 2 to 3 minutes. Remove from heat, and cool to room temperature. Make Vanilla Buttercream, then beat in melted chocolate.

TIP-TOP TOPPINGS: Fresh fruit (blueberries, blackberries), dried fruit (pineapple, cherries, cranberries), caramelized bananas, salted peanuts, sliced almonds, colored sanding sugar, fresh mint.
