Step 1

Preheat the oven to 400 degrees F (200 degrees C). Grease a 12-cup muffin tin or line cups with paper liners.

Step 2

Combine milk, olive oil, leftover cranberry sauce, brown sugar, and egg in a bowl and mix together using an electric mixer. Mix in baking powder, baking soda, salt, cinnamon, and nutmeg. Gradually add flour and oatmeal and mix everything into a smooth batter.

Step 3

Spoon batter into the prepared muffin cups, filling each 3/4 full. Sprinkle with chopped pecans.

Step 4

Bake in the preheated oven until tops spring back when lightly pressed, about 21 minutes. Cool in the tin for 10 minutes. Transfer to a wire rack to cool completely.
