Step 1

Preheat oven to 400 degrees F. Spray a muffin tin with non-stick cooking spray and set aside.

Step 2

In a large bowl, combine the flour, sugar, baking powder and salt with a wire whisk. In a medium bowl, beat the milk, melted butter, egg and vanilla extract with a fork until well blended. Add the milk mixture to the the flour mixture and stir until just combined (the batter will be lumpy.)

Step 3

Fill the muffin-pan cups one-third full with batter. Drop a teaspoon of preserves on top of the batter. Top with the remaining batter. Bake until a toothpick inserted in the center of the muffin comes out clean, 20-25 minutes. Allow to cool for 1 minute, then remove muffins from pan. Allow to cool on a wire rack. Store leftovers in a sealable container.
