Steel-Cut Oat Muffins

Preheat the oven to 350 degrees F (175 degrees C). Line a 12-cup muffin tin with foil liners. Spray liners with cooking spray.

Place oats into a bowl and add milk. Let stand 10 minutes.

Mix egg, oil, and prunes together in a bowl. Add oat mixture and stir to combine.

Combine flour, sugar, baking powder, and salt in a bowl and mix well. Pour flour mixture into oat mixture and stir batter gently until just blended.

Spoon batter into the prepared muffin cups, filling each 2/3 full.

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