Gluten-Free Oat Flour Blueberry Muffins with Almond Flour

These tender, naturally sweetened muffins combine oat flour and almond flour for a wholesome base that's both gluten-free and delicious. Fresh blueberries burst throughout each bite, while coconut oil and applesauce keep them moist without butter. The batter comes together quickly and bakes into beautifully domed muffins perfect for breakfast, snacks, or brunch gatherings. What makes this recipe special is the careful balance of wet ingredients that prevents the coconut oil from seizing while creating consistently fluffy results.

Tips

Tip 1

Warming the water and milk prevents the melted coconut oil from solidifying when mixed with cold liquids, ensuring smooth batter.

Tip 2

Fill muffin cups all the way to the top for bakery-style high-topped muffins, or 3/4 full for standard-sized muffins.

Tip 3

The raw batter appearance closely matches how the muffins will look when baked, so smooth into desired dome shape before baking.

FAQ

Can I use frozen blueberries instead of fresh?

Yes, but don't thaw them first. Toss frozen blueberries in a little flour before folding into batter to prevent sinking and bleeding.

How can I tell when the muffins are done?

Insert a toothpick into the center of a muffin. When it comes out clean or with just a few moist crumbs, they're ready.

Can I freeze these muffins?

Yes, wrap cooled muffins individually and freeze for up to 3 months. Thaw at room temperature or microwave for 20-30 seconds.
