How to Make Perfect Oatmeal Muffins
PREP. Preheat oven to 425 degrees. Line a standard size muffin tin with liners, set aside
COMBINE. In the bowl of a stand mixer fitted with the paddle attachment, add the butter and canola oil. Add sugars, then mix on low until combined, about 1 minute.
MIX. With mixing speed on low, add the buttermilk, then add the eggs one at a time, then vanilla. Mix just until combined.
WHISK. In a separate mixing bowl, whisk together the flour, oats, baking powder, cinnamon, and salt. With mixing speed on low, gradually add the the dry ingredients (along with the apples if using) into the wet ingredients and mix just until combined.
DIVIDE. Divide the batter between the liners.
TOPPING. To make the topping, combine all the ingredients in a small mixing bowl and toss until moist. Sprinkle over top of the muffins.
BAKE. Place in the oven and bake for 8 minutes, then reduce oven temperature to 350 degrees and bake for 12 additional minutes.
COOL & SERVE. Remove from the oven and allow to cool in the pan for 5 minutes before removing and transferring to a wire rack to cool completely.
Recipe Tips
What kind of oats to use? Use old fashioned oats/whole oats because it will give you the best texture. Don’t use steel cut, instant, or quick oats.
Make them moist: Moist muffins are made with lots of wet ingredients like maple syrup, sour cream, buttermilk, molasses, and/or honey. This recipe specifically uses buttermilk to give you a nice moist muffin batter.
How much to fill muffin tins? Fill muffins about â…” of the way, the batter will puff up to fill the rest of the tin and puff up and create domed tops.
Freezing/reheating: Freeze your muffins in an airtight bag for up to 3 months. When you’re ready, thaw them in the fridge overnight and then bring to room temp on the counter. If you like, pop them in the microwave for 30 seconds or so until they are nice and warm!
