Classic Oatmeal Muffins Recipe

These Classic Oatmeal Muffins are simple, wholesome, and irresistibly good. We made a few healthy swaps to keep this recipe 100% whole grain and naturally sweetened, and as a bonus, it’s lower in fat than many traditional muffin recipes. They come together quickly and make a great grab-and-go breakfast, snack, or lunchbox treat.

Our Favorite Healthy Oatmeal Muffins

These oatmeal muffins have become a staple in our kitchen because they are quick to mix, packed with nutritious ingredients, and versatile enough to adapt to many flavor combinations. Make a double or triple batch and freeze extras so you always have a wholesome muffin ready when you need one. They’re also family- and toddler-friendly.

The recipe uses both rolled oats for texture and ground oat flour to contribute whole-grain flavor. We combine white whole wheat flour with oat flour to keep the muffins light yet hearty. Minimal oil and natural sweeteners keep them moist without excess saturated fat.

The Healthy Swaps We Made

Flour: Instead of all-purpose flour, this recipe uses white whole wheat flour and ground oat flour for a whole grain base that stays tender. If you don’t have oat flour, simply blend rolled oats into a fine flour in a blender or food processor.

Sugar: We replace refined cane sugar with a mix of coconut sugar and pure maple syrup for depth and natural sweetness.

Fat: This recipe requires only 2 tablespoons of melted coconut oil. Mashed banana supplies additional moisture and helps reduce the total fat while keeping muffins tender. If you prefer, replace the mashed banana with an equal amount of unsweetened applesauce.

Milk: Unsweetened almond milk keeps the batter dairy-free, but any milk or milk alternative works well here.

Oatmeal Muffin Variations

Use this base recipe to customize your own flavor combinations. Here are a few ideas to get you started:

• Lemon Blueberry: Stir in 1 tablespoon of fresh lemon zest and about 3/4 cup fresh blueberries for bright, fruity muffins.
• Sea Salt Chocolate Chip: Add a handful of chocolate chips to the batter and finish each muffin with a pinch of flaky sea salt for a sweet-and-salty twist.
• Carrot Cake: Fold in 3/4 cup grated carrot with 1/2 teaspoon ground cinnamon, 1/4 teaspoon ground ginger, and a pinch of allspice for a spiced, wholesome muffin.

How to Freeze These Oatmeal Muffins

Freezing muffins makes it easy to enjoy homemade baked goods without the rush. Follow these simple steps to freeze and thaw properly:

1. Cool the muffins completely on a wire rack to prevent condensation in the freezer.
2. Place the cooled muffins on a baking sheet in a single layer and freeze for at least two hours until solid.
3. Transfer the frozen muffins to a freezer-safe, gallon-size bag or an airtight container. Remove as much air as possible before sealing.
4. Label the bag with the name and date; muffins will keep well for up to three months in the freezer.

To thaw: Remove a muffin from the freezer and let it sit at room temperature for about 30 minutes, or warm briefly in the microwave for a minute or two. If you’re taking a muffin with you, move it from the freezer to a to-go container in the morning and it should be fully defrosted by the time you’re ready to eat it.

Ingredients

Instructions

1. Preheat the oven to 350ºF (175ºC). Line a 12-cup muffin tin with paper liners or lightly grease it.
2. In a large bowl, whisk together the white whole wheat flour, oat flour, rolled oats, coconut sugar, baking soda, and salt until evenly combined.
3. In a separate bowl, whisk the eggs. Add the maple syrup, almond milk, and mashed banana, mixing until smooth.
4. Pour the wet ingredients into the dry ingredients and stir until just combined. Avoid overmixing to keep muffins tender.
5. Stir in the melted coconut oil until incorporated. If adding mix-ins (blueberries, chocolate chips, grated carrot), fold them in now.
6. Divide the batter among the muffin cups, filling each about three-quarters full. Sprinkle additional rolled oats on top for texture.
7. Bake at 350ºF for 20–23 minutes, or until a toothpick inserted into the center comes out clean. Cool in the pan for a few minutes, then transfer to a wire rack to cool completely.
