As you probably know, muffins are a type of quick bread that usually comes together in no time at all. The only requirements are two bowls and a mixing spoon.

Let me show you how in just half an hour, you could be enjoying the best blueberry oatmeal muffins ever!

HOW TO MAKE BLUEBERRY OAT MUFFINS:

The first thing we are going to do is soak the oatmeal in buttermilk. It is important not to skip this step as this will contribute immensely to the soft, tender crumb of these blueberry muffins.

In the meanwhile, measure out the dry ingredients in another bowl and whisk them together. Set it aside.

Whisk an egg in the oat mixture along with the oil. Make sure to properly whisk these ingredients together.

Add this liquid mixture to the flour mixture and with a wooden spoon, mix only until combined. Then gently add in the blueberries. A few more gentle stirs and that’s it.

Portion the batter in a muffin container that has been lined with paper cups and bake in a preheated oven. In about twenty minutes, you will have the best blueberry muffins with oatmeal.

How to make buttermilk out of regular milk?

If you do not have buttermilk, you can still make these wonderful muffins. Here’s how: measure one tablespoon of lemon juice or white vinegar and place it in a measurement cup. Pour in enough milk to reach the 1 cup mark. Stir and let stand for at least 5 minutes, so that the acidity can start curdling the milk. I love using buttermilk in pancakes and biscuits. The end product is always fluffy and I love the “tanginess” of flavor it provides.

Recipe origins

It seems like I’ve been collecting recipes all my life. As a teenager, I used to check out cookbooks from the public library and write out the recipes that I liked. Can you imagine that? Did anyone else do that or was it only me? Although it has been over forty years, I still remember sitting in the kitchen and copying recipes…

Needless to say, this obsession with recipes has resulted in quite an assortment of cookbooks over the years. This library of mine also includes collections of recipes that I obtained by mailing in the UPC and/or money order in exchange for the booklets.

I’ve adapted this recipe for buttermilk muffins from the “Robin Hood Recipe Collection”. I’ve been making them for decades and it has always been appreciated by family and friends.

Make sure you try out these Date Bran Muffins, which are a great high fiber muffin to have for breakfast and these super moist Banana Muffins which will intoxicate you with the wonderful aroma while they are baking. Both of these muffins are from the same recipe collection so you know they are good 🙂

From one muffin lover to another, I hope these muffins will become a tradition in your home, too!
