Peanut Butter and Jelly Cupcakes

Directions

• Preheat oven to 350 degrees. Line standard muffin tins with paper liners. Whisk dry ingredients in a large bowl. Cream butter and sugar with a mixer until light and fluffy. Mix in peanut butter. Add eggs, 1 at a time, beating after each addition.
• Reduce speed to low. Mix sour cream and vanilla in a bowl. Add dry ingredients to butter mixture in 3 additions, alternating with wet ingredients and ending with dry. Scrape sides of bowl. Divide batter among muffin cups, filling each 2/3 full.
• Bake cupcakes until testers inserted into centers come out clean, about 20 minutes. Let cool in tins on wire racks. (Unfrosted cupcakes will keep, covered, for up to 3 days.) Once cupcakes are cool, frost tops with peanut butter frosting. Place a dollop of jam in center of frosting. Decorated cupcakes will keep, covered and refrigerated, for up to 2 days.
