Ingredients

• 1 cup All-purpose flour
• 0.5 cup Whole wheat flour
• 1.5 teaspoons Baking powder
• 0.5 teaspoon Baking soda
• 0.25 teaspoon Salt
• 1 teaspoon Ground cinnamon
• 1 cup Cooked oatmeal
• 0.5 cup Brown sugar
• 1 large Egg
• 0.5 cup Milk (any type)
• 0.25 cup Vegetable oil (or melted butter)
• 1 teaspoon Vanilla extract
• 0.5 cup Optional mix-ins (e.g., raisins, chocolate chips, or nuts)

Directions

Step 1

Preheat your oven to 375°F (190°C) and line a 12-cup muffin tin with paper liners or grease the cups with cooking spray.

Step 2

In a large mixing bowl, whisk together the all-purpose flour, whole wheat flour, baking powder, baking soda, salt, and ground cinnamon.

Step 3

In a separate bowl, combine the cooked oatmeal, brown sugar, egg, milk, vegetable oil (or melted butter), and vanilla extract. Mix well until smooth and evenly combined.

Step 4

Pour the wet ingredients into the dry ingredients and gently fold together using a spatula. Do not overmix; the batter should be just combined.

Step 5

If you’re using optional mix-ins like raisins, chocolate chips, or nuts, gently fold them into the batter at this stage.

Step 6

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

Step 7

Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center of a muffin comes out clean.

Step 8

Remove the muffins from the oven and let them cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.

Step 9

Serve warm or at room temperature. Store in an airtight container at room temperature for up to 2 days, or freeze for longer storage.
