Key Ingredients for Oatmeal Muffins
Each ingredient plays an important role in creating the perfect texture and flavor for these muffins.
Dry Ingredients
- All-Purpose Flour (1 ½ cups) – Provides the structure for the muffins. If you want a heartier texture, substitute half with whole wheat flour.
- Baking Powder (1 teaspoon) & Baking Soda (½ teaspoon) – These leavening agents help the muffins rise, creating a light and fluffy texture.
- Ground Cinnamon (1 teaspoon) – Adds warmth and depth of flavor, making the muffins extra cozy.
- Salt (¼ teaspoon) – Enhances all the flavors and balances the sweetness.
- Quick-Cooking Oats (1 cup) – The star ingredient! Oats add a chewy, hearty texture and mild nuttiness. You can also use old-fashioned rolled oats for more texture.
Wet Ingredients
- Whole Milk (¾ cup) – Keeps the muffins moist and soft. You can substitute with almond milk or oat milk for a dairy-free version.
- Vegetable Oil (½ cup) – Adds moisture, making the muffins soft and tender. Melted butter or coconut oil can also be used.
- Light Brown Sugar (½ cup, packed) – Gives the muffins a subtle caramel-like sweetness while keeping them moist. You can use honey or maple syrup as a natural alternative.
- Eggs (2, large) – Help bind the ingredients and provide structure. Room temperature eggs work best for even mixing.
- Vanilla Extract (1 teaspoon) – Enhances the overall flavor and adds a touch of sweetness.
Optional Add-Ins for Extra Flavor
Customize your muffins by adding mix-ins:
- Chopped Nuts (½ cup) – Walnuts, pecans, or almonds add crunch and a nutty depth.
- Raisins or Dried Cranberries (½ cup) – Add natural sweetness and a chewy texture.
- Chocolate Chips (½ cup) – For a sweet treat, use semi-sweet, dark, or white chocolate chips.
- Shredded Coconut (¼ cup) – Adds a tropical touch and extra chewiness.
- Fresh or Frozen Berries (½ cup) – Blueberries, raspberries, or diced strawberries work well.

Step-by-Step Instructions for Making Oatmeal Muffins
1. Preheat and Prepare the Pan
Preheat your oven to 375°F (190°C). This temperature allows the muffins to rise properly without over-browning.
- Grease a 12-cup muffin tin with non-stick spray or line it with paper muffin liners for easy removal.
2. Soak the Oats for Maximum Moisture
- In a medium bowl, combine the quick-cooking oats (1 cup) and milk (¾ cup).
- Stir to coat the oats evenly and let them soak for 10 minutes. This softens the oats, creating a tender texture in the muffins.
3. Mix the Dry Ingredients
- In a large mixing bowl, whisk together:
- All-purpose flour (1 ½ cups)
- Baking powder (1 teaspoon)
- Baking soda (½ teaspoon)
- Ground cinnamon (1 teaspoon)
- Salt (¼ teaspoon)
- Whisk until well combined and no lumps remain. Set aside.
4. Prepare the Wet Ingredients
- In another medium bowl, whisk together:
- Vegetable oil (½ cup)
- Light brown sugar (½ cup, packed)
- Eggs (2, large, room temperature)
- Vanilla extract (1 teaspoon)
- Mix until smooth and well combined.
5. Combine Wet and Dry Ingredients
- Pour the soaked oats and milk mixture into the wet ingredients.
- Stir gently to combine.
- Gradually add the dry ingredients into the wet mixture, stirring just until no streaks of flour remain.
- Avoid over-mixing—this can make the muffins dense instead of soft and fluffy.
6. Add Optional Mix-Ins (If Using)
If adding any extra ingredients like chocolate chips, nuts, or fruit, fold them in gently at this stage.
7. Fill the Muffin Tin
- Use a spoon or cookie scoop to evenly divide the batter among the 12 muffin cups.
- Fill each cup about ¾ full—this allows room for the muffins to rise without overflowing.
8. Bake the Muffins
- Place the muffin tin in the preheated oven (375°F/190°C).
- Bake for 20-25 minutes, or until the tops are golden brown and a toothpick inserted in the center comes out clean.
9. Cool and Serve
- Let the muffins cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.
- Enjoy warm or at room temperature.
