Step 1

Preheat oven to 375°F. Coat a muffin tin with cooking spray.

Step 2

Combine oats, milk, applesauce, brown sugar, lemon zest, lemon juice, eggs, baking powder, vanilla and salt in a large bowl. Fold in frozen blueberries. Divide the mixture among the prepared muffin cups, about 1/3 cup each. Bake until a toothpick inserted in the center comes out clean, about 25 minutes. Cool in the pan for 10 to 15 minutes, then turn out onto a wire rack. Serve warm or at room temperature.
