Go small…

Use smaller blueberries that is! I found that using smaller blueberries as opposed to large ones (like the size Costco sometimes carries) makes a big difference in how these blueberry oat muffins blend together. Using smaller blueberries makes the batter evenly spread out and you get just the right amount of baked good with juicy berries in every bite.

What kind of gluten-free flour should I use?

I prefer to use Bob’s Red Meal 1-to-1 Baking Flour. It is dairy-free also and lends a nice and moist baked good and can be found on Amazon. I also suggest my own special gluten-free flour blend (that I make and use at home) that can be found in my cookbook, the Dairy-Free Gluten-Free Baking Cookbook.

Are oats (and Oatmeal) gluten-free or not?

Oats are not gluten-free unless they say certified gluten free. The reason behind that is that oats are harvested near wheat and cross contamination is likely to occur. Making sure the are certified assures that the oats were grown and processed on a farm and factory that does not contain gluten and wheat products. Gluten-free oats are available online here or at some specialty stores.


Blueberries: this is the last ingredient but the best😊. Blueberries are rich in antioxidants and fiber. Adding them to baked goods or over oatmeal is an excellent way to get them in your diet. Blueberries are also known to lower weight and blood pressure.

Gluten-Free Flour Blend: Don’t be scared by the thought of a dry baked good. These are my moistest muffins yet! The other ingredients compensate the blend. You can find a blend at most stores, just look for a gluten-free baking blend or baking mix that is already pre-made.

Rolled (Old-Fashioned) Oats: Oats add so much texture to these gluten-free blueberry muffins. They are the heart of the recipe and adds fiber to you diet, which is known to help reduce cholesterol and flush away toxins.

Maple Syrup: Whenever I make baked goods I love using maple syrup in place of white sugar. It adds antioxidants and essential B vitamins and is 100% natural!

Dairy-Free Yogurt & Milk: Thank goodness for easily available dairy-free yogurt and milk at stores. Most are fortified with extra vitamins and mineral and are calmer on the belly for those with a lactose intolerance. These two ingredients in gluten-free blueberry muffins add the moisture and fluff and bind everything together so it does not crumble😊.

Lemon Zest: Lemons are loaded with vitamin C and antioxidants. Adding them to these gluten-free muffins compliments the berries and brings out more flavor!

Coconut Oil: I use coconut for oil, which has healthy saturated fats that are known to be a natural anti-bacterial and speed up the metabolism. Win-win right there! Although, you can also use avocado oil or melted butter (or dairy-free butter) in these muffins.

How to make gluten-free blueberry muffins

Step 1: Preheat the oven and prepare a muffin tin with liners. Spray the liners with cooking spray to avoid the muffins from sticking.

Step 2: Combine the dry ingredients together in a large bowl (see this article on tips for measuring how many dry ounces in a cup if needed). Pour in the coconut oil and stir to the dry ingredients.

Step 3. In a small bowl, whisk together the remaining liquid ingredients and lemon zest. Then pour the liquid ingredients with the dry ingredients. Fold in the blueberries carefully and let the batter set about 5 minutes to soak the oats.

Step 4. Scoop the batter into the prepared muffin cups, filling each to the top. Bake 20-22 minutes until golden on the top and a toothpick inserted comes out clean. Remove from the oven and let them cool for 1-2 minutes and transfer to a cooling rack.


Can I use frozen blueberries instead of fresh blueberries?

I prefer fresh blueberries, but yes frozen can be use. Thaw the fruit first then drain out an extra juice from the berries before using.

How to store muffins

Gluten-free muffins tend to dry out much faster than those with gluten. I suggest storing these muffins in an airtight container in the refrigerator. They will mold fast, after about 3 days since the blueberries add lots of moisture. Consume within 3 days for the best taste. Heat them in the microwave or oven slightly to warm them before serving.

Can I freeze blueberry and oat muffins?

Yes. Although they are best fresh, they can be stored in a sealed freezer bag with air removed for 1 month. At most, 3 months.
