2 c. all-purpose flour
1/2 c. sugar
2 1/2 tsp. baking powder
1/2 tsp. Salt
3/4 c. crunchy-style peanut butter
3/4 c. milk
2 eggs
1/4 c. fruit preserves

Preheat oven to 400 degrees. Combine flour, sugar, baking powder, and salt in a mixing bowl. Cut in peanut butter with two knives or a pastry blender until mixture resembles coarse crumbs. Add milk and eggs all at once, stirring just until flour is moistened. Place 2 tablespoons of the batter in greased, fluted, or plain muffin cups. Place 1 teaspoon of preserves in center of batter and top with 2 tablespoons more batter. Repeat, making 12 muffins. Bake in a 400 degree oven for 15-17 minutes.
