These Gluten-Free Blueberry Muffins are soft muffins filled with sweet blueberries and topped with a cinnamon crumble. They are the perfect breakfast treat!

Homemade blueberry muffins are a fan favorite in my house. My husband is usually stealing one out of the muffin pan the second they come out of the oven. These Gluten-Free Blueberry Muffins are moist and fluffy with a sweet cinnamon crumb topping. They will blow you away and I am absolutely sure that no one will know they are gluten-free muffins! I’ve also included the measurements for regular flour, in case you’re not looking for a GF recipe!
Ingredients for Gluten-Free Blueberry Muffins:
Ingredients for Gluten-Free Muffins:
- Bob’s Red Mill GF 1:1 Baking Flour OR All-purpose Flour. I prefer Bob’s Red Mill GF Flour, but you can use whatever you like best. You might have to adjust the amount if it doesn’t measure the same as regular flour.
- Granulated sugar. This will sweeten the blueberry muffins.
- Salt. Salt is a must in baked goods. It will help to balance out the sweetness and improve the overall flavor.
- Baking powder. This will help the muffins to rise.
- Vegetable oil. I usually prefer butter over vegetable oil, but it helps to make these muffins extra moist.
- Egg. It will be easier to incorporate the eggs into the batter if they are at room temperature.
- Milk. This is a binder and will help keep the muffins moist.
- Blueberries. You can use fresh or frozen blueberries.
Ingredients for Cinnamon Crumble:
- Granulated Sugar. See above note.
- Bob’s Red Mill GF 1:1 Baking Flour OR All-purpose Flour. See above note.
- Unsalted Butter. The butter needs to be kept cold until the muffins are put in the oven.
- Ground Cinnamon. This will add flavor to the crumble.

How to make Gluten-Free Blueberry Muffins:
Crumble Topping
Step 1: In a small bowl, combine sugar, GF flour, butter, and cinnamon. Using clean hands or a fork to mix. You want to break up the butter until the whole mixture has a coarse texture. There will be bigger chunks of butter as well.
Step 2: Place in fridge until ready to use.
Gluten-Free Blueberry Muffins
Step 1: Preheat your oven to 350 degrees (F). Line a muffin pan with muffin liners. Set aside.
Step 2: In a medium bowl, combine the GF flour, sugar, salt, and baking powder. Whisk until free of lumps.
Step 3: This part is a little confusing, but you only need 1 cup total of liquid. So take 1 cup measuring cup and add 1/3 cup of vegetable oil and the egg. Fill the cup up the rest of the way with milk. Add to flour mixture and combine.
Step 4: Fold in the blueberries.

Step 5: Fill the cups of the muffin pan with batter. Top with crumb topping.

Step 6: Bake for 25-30 minutes or until a toothpick inserted into the center of one of the muffins comes out with only a few moist crumbs.
