Easy Oat Muffins with Cinnamon Sugar

Easy Oat Muffins are soft, golden, and perfectly domed! They come together quickly from pantry staples and make a wholesome breakfast or snack.

When you crave something quick and warm from the oven, make oat muffins!

From oatmeal and granola to cookies, scones, and bread, oats always bring something cozy to a recipe. It’s the whole grain that doesn’t have any of the coarseness we associate with whole grains, so I even like to incorporate oat flour into cakes. If you’ve tried my Apple Cider Doughnut Cake or my Glazed Old Fashioned Buttermilk Doughnut Cake you’ll know how it creates a soft, fluffy crumb.

These easy oat muffins are high risers!

I was inspired by these King Arthur Flour muffins, but this recipe is based on the same recipe as my Pear Muffins with Hazelnut Streusel, and my Orange and Cardamom Muffins. As you can see, they rise really well, it’s one of the reasons I love this recipe. Who doesn’t love a high rise muffin top?

I really like these minimalist muffins as-is, but you can totally use them as a canvas for other additions. Just open up your pantry and design your own version ~

  • Add some cinnamon, cardamom, or vanilla bean to the batter.
  • Fold in dried fruit like raisins or cranberries. Chop larger dried fruit like apricots or figs.
  • Nuts like walnuts, hazelnuts, or almonds can be added to the batter or sprinkled on top.
  • Top with a quick streusel with butter, sugar, flour and oats.
  • Add mini chocolate chips!

Stash the batter in the fridge overnight

Get a head start on these muffins and make the batter the night before. You’ll have fresh baked muffins in the morning with no effort ~ it’s the ultimate luxury.

Instructions

  • Mix until everything is well incorporated and there are no dry pockets of flour left.
  • Spoon the batter into your prepared muffin tin. Fill them almost to the top for 9-10 larger muffins, or about 3/4 full for about a dozen medium sized muffins.
  • For the topping, mix the cinnamon and the granulated sugar together, and sprinkle it on top of the muffins, along with the oats, if desired.
  • Bake for 20-25 minutes until risen and starting to turn golden around the edges.
  • Remove from the oven and allow to cool partially in the pan before removing to a baking rack to cool completely.

    These muffins were perfect for me. A whole grain feel without being too dense, and a nice hint of sweetness,not overpowering.

    Not sure if I missed a step (I went back and rechecked a few times) but these came out very bland. The tops were yummy with the cinnamon sugar topping but the rest of the muffin was left on the late by my boys.
