They are dense in the best way possible, packed with hearty oats, and have that perfect bakery-style dome with a crunchy, glittering sugar topping.

Here is how to make them in just a few simple steps.

Ingredients You'll Need

For the Muffins:

• 1 ½ cups old-fashioned rolled oats

• 1 ¼ cups all-purpose flour

• 1 tsp baking powder

• ½ tsp baking soda

• 1 tsp ground cinnamon

• ½ tsp salt

• ½ cup dark brown sugar (packed)

• ⅓ cup pure maple syrup

• ½ cup unsalted butter (melted and cooled)

• 2 large eggs (room temperature)

• ½ cup buttermilk (or whole milk)

• 1 tsp pure vanilla extract

For the Crunchy Topping:

• 2 tbsp coarse sugar (like Demerara or Turbinado sugar)

Step-by-Step Instructions

1. Prep and Soak

Preheat your oven to 400°F (200°C) and line a 12-cup muffin tin with paper liners. In a medium bowl, whisk together the rolled oats, flour, baking powder, baking soda, cinnamon, and salt.

2. Mix the Wet Ingredients

In a separate large bowl, whisk the melted butter, brown sugar, and maple syrup together until smooth and no lumps remain. Whisk in the eggs one at a time, followed by the buttermilk and vanilla extract.

3. Combine

Pour the dry ingredients into the wet ingredients. Fold gently with a spatula just until combined. Pro-tip: Don't overmix! Overmixing develops the gluten and makes the muffins tough instead of fluffy. Let the batter sit for 5 minutes so the oats can absorb some of the liquid.

4. Scoop and Top

Divide the batter evenly among the 12 muffin cups. Sprinkle the coarse sugar generously over the top of each muffin. This gives them that signature bakery crunch.

5. Bake to Perfection

Bake at 400°F (200°C) for 5 minutes, then—without opening the oven door—turn the heat down to 350°F (175°C) and bake for another 13–15 minutes. A toothpick inserted into the center should come out clean.

Why the temperature drop? Starting at a high heat activates the leavening agents quickly, giving you those beautiful, tall muffin tops!

Let them cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.

Quick Tips for Success

• Want more texture? Toss a half-cup of chopped pecans or walnuts into the batter.

• Storage: Keep these in an airtight container at room temperature for up to 3 days, or freeze them for up to 2 months. Just microwave for 20 seconds to get that fresh-out-of-the-oven warmth!
