Easy Oatmeal Muffins

Step 1
Preheat the oven to 425 degrees F (220 degrees C). Grease 12 standard muffin cups or line with paper muffin liners.

Step 2
Combine milk and oats in a small bowl; let soak for 15 minutes.

Step 3
Beat together egg and oil in a large bowl; stir in oat mixture. Sift together flour, sugar, baking powder, and salt in a separate bowl. Stir flour mixture into wet ingredients until just combined. Spoon batter into the prepared muffin cups until 2/3 full.

Step 4
Bake in the preheated oven until a toothpick inserted into the center of a muffin comes out clean, 20 to 25 minutes.
