Oatmeal Muffins

Oatmeal Muffins are a hearty (if not glamorous) breakfast muffin. Soft and moist thanks to a blend of oil and butter and a splash of buttermilk. Textured with oats, and full of flavor thanks to brown sugar, vanilla, cinnamon and nutmeg.

With a hearty texture reminiscent of an oatmeal cookie, these oatmeal muffins are a classic, reliable muffin that’s likely to join the ranks of your favorite breakfast staples (buttermilk pancakes, anyone?). Be sure to check out the how-to video below the recipe!

We’re about due for a new muffin recipe around here.

How about a good, solid, reliable oatmeal muffin. Sure, it might not be the most glamorous (it’s no fluffy frosted cinnamon roll, after all), but is still sure to brighten up your Monday morning.

It’s a practical muffin with practical ingredients. A blend of butter and oil for the best flavor and moisture. A generous splash of buttermilk (or this buttermilk substitute) for flavor and tenderness. An extra egg white for extra rise and a nice proud muffin top (let’s give ourselves a point for extra protein, too). Generously flavored with molasses-rich brown sugar, vanilla, cinnamon, and nutmeg.

Oh, and who could forget that glorious mountain of streusel topping (recipe for that adapted from the top of my favorite coffee cake). This oatmeal muffin is sounding more and more glamorous by the minute, now that I think of it.

Tips for Making Oatmeal Muffins

If you’ve tried some of my other muffin recipes (my chocolate chip muffins, by chance?), these tips might not be new to you. They’re important, though, and bear repeating.

Measure your flour with a light hand

If you are using cups (rather than weights), never scoop your flour directly into your measuring cup. This increases your chance of over-measuring your flour, leaving you with too dense, too dry oatmeal muffins. Instead, stir your flour and spoon it into your measuring cup, then level off the cup with the back of a knife. Even better, get a kitchen scale (this is the one I use, inexpensive and accurate, affiliate link), this was a game changer for me!

Don’t over-mix your ingredients!

Over-mixing is one of the cardinal sins of muffin and cake-making. Stir your ingredients too thoroughly and you’ll end up with dense, dry results. Your dry and wet ingredients should be combined gently and hand-stirred (use a spatula or spoon, and never an electric mixer) and noticing a few fine flour streaks in the batter is fine.

Oh, and another cardinal sin: over-baking. Even a minute or two too long in the oven can degrade the end result. Make sure your oven isn’t running hot and always start with just a little less baking time than you think you need. You can always add another minute or two to the end.

Two oven temperatures is better than one

We start our oatmeal muffins in a hot, 425F oven and then after a few minutes (without opening the oven door) we drop that temperature to 350F to complete the baking process. Baking our muffins this way allows the batter to begin to rise, and then dropping the temperature allows  the interiors of your muffins to finish cooking without drying out. This gives us tall muffin tops and soft, moist centers.

What Kind of Oats Should I Use for Oatmeal Muffins?

I tried this recipe with both old fashioned and instant oats and it works both ways, with just subtle differences.

Using old fashioned oats will make your muffins overall lighter and slightly fluffier, but you’ll have more of a chewy texture from the oats. They’re more… noticeable… in every bite. That’s not a bad thing, just worth noting!

Using instant oats will make your oatmeal muffins a bit denser (the oats in general will make them more dense than your typical muffin) but I found that, if I had to choose, I preferred the finer texture that resulted from using instant oats.

Enjoy!
