How to Make Blueberry Oat Muffins

These muffins are healthier and lighter than many other sugar-laden muffin recipes. They have a bit of sugar, but most of the sweetness in this recipe comes from the blueberries and orange juice. 

Plus, these muffins have extra fiber from whole wheat flour and rolled oats. If you haven’t baked with whole wheat pastry flour before, look for it in the baking aisle. There are several specialty brands that produce it, as well as Bob’s Red Mill.

If you can’t find whole wheat pastry flour, you can substitute regular all-purpose flour.

When mixing the muffin batter, be careful not to overmix it. Just stir until you have a uniform batter, a few lumps are fine!

Likewise, it’s important to gently fold in your blueberries. If muffin batter is overmixed, your muffins will come out dense, flat, and tough.  Plus, heavy mixing can burst your delicate berries and stain your oat muffins!

Portioning Muffin Batter

I like to use a disher or scoop to evenly portion out the muffin batter. You want to fill each muffin well no more than ¾ of the way full. Remember, the muffins will rise in the oven!

Fresh vs. Frozen Blueberries

I prefer to use fresh berries but frozen blueberries will work as well. Don’t thaw the berries before adding them to the batter. Note that your cook time will be longer with frozen berries.

Storing Muffins

Store fully cooled muffins in an airtight container or zip-top bag for up to five days at room temperature. Or freeze muffins for up to 6 months. Defrost on the counter for a few hours or pop one into the microwave in 30-second increments, until warmed through.
