Preheat oven to 400°F (200°C). Spray a 12-cup muffin pan with cooking spray.
In a medium bowl, whisk together flour, sugar, baking powder, and salt.
In a large bowl, whisk together milk, oil, and eggs. Add flour mixture, stirring just until dry ingredients are moistened. Spoon about 3 tablespoons batter (about 52 grams) into each prepared muffin cup. Spoon 1 teaspoon fruit spread (about 6.5 grams) (is using) in center of batter in muffin cups. Spread about 2 tablespoons batter (about 35 grams) onto fruit spread.
Bake until golden brown, 15 to 17 minutes. Let cool in pan on a wire rack for 10 minutes. Remove from pan; serve warm.
