How to Make Oatmeal Muffins

This healthy muffin recipe makes one of my family’s favorite muffins! They make a great grab-and-go snack for busy families! Get the full recipe with ingredients in the recipe card below. Here are the 6 easy steps to follow for perfect oatmeal muffins:

  1. Mix dry ingredients. In a large bowl combine the quick oats, flour, granulated sugar, baking powder, baking soda, salt, and cinnamon. Stir together and set aside.

  1. Mix wet ingredients. In a separate bowl combine the eggs, buttermilk, olive oil, and vanilla extract. Stir to combine with a fork or spatula.
  2. Combine wet and dry ingredients. Gradually mix in the dry ingredients, mixing just until combined. Stir in any additional add-ins like blueberries or chocolate chips now. The batter will be very thick!
  3. Rest batter and prep oven. Cover the bowl with a towel and allow the batter to rest for 15 minutes. During this time, preheat the oven to 425ºF.
  4. Fill muffin pan. For bakery style muffin tops, line a 12-cup muffin tin with 6 muffin liners, meaning you’ll only fill every other muffin well with batter. Spoon batter into the liners, filling the liners to the top with batter, about 6-8 heaping tablespoons. Use a butter knife to smooth the tops of the muffins if lumpy. Top with a sprinkle of quick-cooking oats and sanding sugar. 
  1. Bake and cool. Bake for 7 minutes at 425ºF, then keep the muffins in the oven, and turn the temperature down to 350ºF and bake for 11-14 minutes or until a toothpick inserted in the center comes out clean. Allow the muffins to cool in the pan for 15 minutes before removing. Repeat with the remaining batter, bumping the temperature back up to 425ºF.

How to Create Bakery Style Muffins

Bakery style muffins are known for their domed tops. Plus who doesn’t love them? I used a few techniques to help “lift” these muffins so they would have large, domed tops!

1. The Rest Period

Let the batter rest for 15 minutes after it’s mixed and before you scoop it into the muffin pan. During the resting period, starch molecules in the flour are absorbing the liquid in the batter, causing them to swell and giving the batter a thicker consistency (ref the kitchen whisper). Our 15 minute rest is just a quick rest. 

2. Fill Every Other Muffin Cup

This tip has been a game changer! For bakery style muffin tops, line a 12 count muffin pan with 6 muffin liners, meaning you’ll only fill every other muffin well with batter. Filling every other cup allows the muffins to spread and dome without running into each other. This technique also encourages the muffins to brown, creating a golden muffin top.

3. Fill Them To The Top

Fill your muffin liners to the top with batter. Yes, this goes against everything you’re heard but it’s important in helping the muffin gain that height.

4. Bake at High Temperature Initially

Bake the muffins at a high temperature (425ºF) initially, then lower to 350ºF. Starting the muffins off at a higher temperature causes the batter to rise rapidly, setting the outer surface of the muffin, producing a dome shape.

Variations to this Oat Muffin Recipe

One of my favorite things about this recipe is that it’s both delicious as-is and perfect for customizing with add-ins. One of my favorite ways to use up blueberries is to make blueberry oatmeal muffins! Simply mix in 1 ½ to 2 cups of the add-in of your choice to the muffin batter when mixing in the last bit of dry ingredients. Here are some add-in ideas:

  • Blueberries
  • Chopped Strawberries
  • Chocolate Chips
  • Chopped Nuts
  • Raisins
  • Dried cranberries

I’ve made this recipe with both regular all-purpose flour and gluten free all-purpose flour with awesome results on multiple occasions. I recommend King Arthur’s Gluten Free Measure for Measure Flour. Use it as a one for one substitute for regular flour. Be sure to use gluten free quick cooking oats as well if making gluten free.

How to Store Oat Muffins

Storing and Freezing Muffins

Muffin Storage

If you’ll be eating the muffins within 24 hours of baking, you can leave them uncovered on the counter. The muffins will not dry out while left at room temperature for 1 day. 

In fact, muffins are so moist they can become soggy and those crunchy, sugary tops can disappear when stored in an airtight container.

But I have a trick to help that – paper towels. 

For longer storage, 2-4 days, line the bottom of an airtight container with paper towels. Place the muffins in a single layer in the container then cover the muffins with any additional layer of paper towels. The paper towels will act like a sponge, absorbing the moisture they release while they are stored. 

If the paper towels become too moist around day 2 or day 3, replace them with fresh paper towels. 

How To Freeze Muffins

Individually wrap each muffin in plastic wrap. Then place them in a ziploc bag or airtight container and place in the freezer for up to 3 months.

To thaw, leave them at room temperature until defrosted, about 1 hour. Or unwrap them and microwave at 20 second intervals until defrosted.

Oatmeal Breakfast Muffins FAQs

Why are my oatmeal muffins dry?

Oatmeal muffins can turn out dry if the flour is not measured properly. Be sure to measure the flour using the spoon and level method.

Why are my muffins dense and not fluffy?

Using too much flour can result in a dense muffin. For best results with the texture of the muffins, properly measure the flour using the spoon and level method. 

What are the health benefits of oatmeal muffins?

Oatmeal muffins are high in fiber, which can help regulate digestion and stabilize blood sugar levels. Oatmeal also benefits heart health due to its soluble fiber. Muffins made with whole grain oats are nutrient-rich, containing vitamins, minerals, and antioxidants, including manganese, phosphorus, magnesium, iron, zinc, and B vitamins.

    These muffins are amazing! I made them gluten-free and used Bob’s Redmill one-to-one. I love them without any extra addition, however, half the batch, I added chocolate chips and toffee bits… I’m thinking a little bit of orange zest would be great in them, but I don’t wanna change anything at all!  They are so so good!
