From the Test Kitchen

Jam-Filled Cupcakes

Prepare as directed above. Before frosting, with the handle of a wooden spoon, make an indentation in the center of each cupcake. Spoon or pipe a scant teaspoon of jam into each indentation. Frost with Sour Cream Frosting. Top with sugar flowers. (Find sugar flowers among baking ingredients at the grocery store, or at baking supply stores.)

Sour Cream Frosting



  1. In large mixing bowl beat butter with mixer 30 seconds; beat in sour cream. Gradually beat in powdered sugar. Beat in vanilla and milk. Use at once or refrigerate up to 3 days. Remove from refrigerator 30 minutes before using. Frost cupcakes with a knife, or spoon frosting into large resealable plastic bag. Snip one corner of bag and squeeze to pipe onto cupcakes.
