Place 33 foil muffin cup liners on a large baking sheet, or place in muffin cups. Divide batter evenly among muffin cup liners, filling about two-thirds full.
Bake at 375 for 17 to 18 minutes or until cupcakes are golden brown and cracks in cakes appear dry.
Cut a deep slit in top center of each cake to form a pocket. Carefully spoon about 1 tablespoon lemon curd into each warm cake.
