Ingredients Notes
Full recipe and ingredients are in the recipe card below. Feel free to scroll through this section to view certain key ingredients we’re using!
- All-purpose flour – This flour is used for the muffins.
- Brown sugar – I used dark brown sugar, but light brown sugar works as well!
- Cornstarch – Optional, but helps enhance the texture.
- Cinnamon - Adds a lot of flavour to these muffins! I also used a pinch of nutmeg and cloves.
- Eggs – Must be at room temperature before starting your bake.
- Oil – I used a flavourless oil.
- Oats - Make sure to use rolled oats, also known as large flake oats. Quick oats will not work for this recipe!
- Sour Cream – The sour cream makes the muffins so soft and delicious!
Step by step instructions
Here is how to make and bake these Apple Oatmeal Muffins. You will need a 12 muffin tin, muffin liners, 2 large mixing bowls, a spatula, and a whisk.
Step 1 – Prep. Line your muffin tin with 12 liners or 8 tulip liners and set aside. Shred one apple, and cut the second apple into small cubes.
Step 2 – Mix together dry ingredients. In a medium-sized bowl, add in the dry ingredients. With a spatula, mix until just completely combined and then set aside.
Step 3 – Whisk wet ingredients. In a large bowl, whisk the wet ingredients; eggs, milk, vanilla, sour cream, oil, and brown sugar. Whisk together.
Step 4 - Combine dry and wet ingredients. Add the dry ingredients into the wet ones. Mix together with a spatula until a soft muffin batter forms.
Step 5 - Add in apples. Mix the apples in until evenly distributed amongst the batter.
Step 6 – Scoop. Evenly divide the batter the liners. I recommend a cookie scooper for even scooping and to minimize the mess. This is optional, but in a small glass mix together cinnamon and sugar. Then sprinkle a bit on top of each muffin.
Step 7 – Bake. Bake the muffins at 425°F for 5 minutes, and then 375°F for 18-20 minutes. They will bake about 20-28 minutes in tulip liners. The muffins are ready when a toothpick inserted comes out clean.
These muffins are best served fresh or next day. They stay good in an airtight container in the refrigerator for up to a week!
Expert Baking Tips
Here are a few expert baking tips from my kitchen to yours
- Use a gram scale. This is how you get the most accurate measurements. You can go from cups to grams in the recipe card below.
- Do not over-mix! A big reason muffins don’t turn out the way you want is because the batter gets over-mixed.
- Shred and dice the apples. I know it's an extra step to do both, but this will give you next level muffin texture!
