Baking Breakfast Brunch Muffins

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.

  • 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.

    I loved how mine turned out! Thank you truly so much! I actually ended up using Almond Flour as a substitute as well as extra virgin olive oil instead of vegetable oil. I was just wondering how many calories are in each medium sized muffin. Thank you so very much!! They are DELICIOUS!

    Love this. I don’t have a muffin mould tray and used my loaf mould- just took 12 min more to bake it. Spooned some peanut butter on a slice and half the loaf is already gone! Perfect afternoon tea when all there’s to do is stay at home.

    Love this quick and easy muffin recipe. The best part is the ingredients are always in the pantry.
    I added coconut flakes for a bit of texture. They reheat wonderfully.

    I made it YUM and got 12 regular sized muffins. I used buttermilk, cardamom and a little cinnamon. I topped mine with my homemade granola then sprinkle of sugar.
    I really love them because they aren’t too sweet. Perfect, thanks!
    Also…I used Old Fashioned oats for the batter and my homemade granola.

    Hi Sue,
    Love your recipes and have tried many of your breakfast recipes. Regarding your muffin recipes, why is it that your muffin recipes, for LARGE muffins never make 12 muffins? Can you tell me how to adjust the muffin recipes so that I can get 12 Large muffins??

    Stay well and safe

    Thanks,

      I don’t really know, off hand, I guess it’s because most muffin recipes are developed from a base that makes 12 normal sized muffins, and I personally prefer them larger so I usually make more like 9. I’d have to bust out my calculator to see if I can adjust the recipe 🙂

    Hi Sue, these look great and I’m dying to make them. Quick question: are you using large flake oats? I’ll post a rating once I’ve made them. Thanks so much and stay safe!

      I used regular Quaker rolled oats Rose. You can use the Old Fashioned variety, or even the quick cooking if that’s all you have.

        Thanks, Sue! So I just made them. I wanted to give them a try because when I used to go into the city for jobs, I would always include time to have an oatmeal muffin and a cup of tea beforehand to calm my nerves. I just tried a still warm top and they are delicious! I got nine big muffins (because big is ALWAYS better!) and I used large flake oats and soy milk. This recipe is keeper! Thanks so much!!
