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 and cannot be substituted for any other.

Brown sugar – I used light brown sugar, but dark brown sugar works as well!

Chocolate chips - I find mini chocolate chips work best for these muffins as they create perfect little pockets of chocolate. You can also use semi-sweet chocolate chips, but there will be more chocolate in the muffin.

Cornstarch – Used to enhance the texture.

Cinnamon - Adds a lot of depth to the flavour! 

Eggs – Must be at room temperature before starting your bake.

Oil – I used a flavourless oil. You can use any type of oil, but flavoured ones will slightly change the taste.

Oats - Make sure to use rolled oats, also known as large flake oats. Quick oats will not work for this recipe!

Step by step instructions

Here is how to make and bake these Chocolate Chip Oatmeal Muffins. You will need a 12 muffin tin, muffin liners, 2 mixing bowls, a spatula, and a whisk.

Step 1 – Prep. Line your muffin tin with 12 liners and set aside. If you need a recommendation, this is my favourite tin.

Step 2 – Mix together dry ingredients. In a medium-sized bowl, add in flour, oats, cinnamon, salt, cornstarch, baking powder, and baking soda. Using a spatula, mix until just completely combined.

Step 3 – Mix wet ingredients. In a large bowl add eggs, vanilla, brown sugar, oil, and sour cream. Whisk until combined.

Step 4 - Combine dry and wet ingredients. Add the dry into the wet and using a spatula, gently fold until a soft batter forms.

Step 5 - Add in chocolate chips. Mix in the mini chocolate chips until just combined. Do not over-mix!

Step 6 – Scoop. Evenly divide the batter between 12 liners. Using a cookie scooper helps big time to minimize the mess. Sprinkle extra mini chocolate chips on top (optional).

Step 7 – Bake. Bake the muffins at 425℉/218℃ for 5 minutes and then 375°F for 14-18 minutes. The muffins are ready when a toothpick inserted comes out clean.

These muffins stay fresh covered at room temperature for up to 3 days, and 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. I cannot emphasize this enough! It is the most accurate way of measuring your ingredients in the kitchen. This is one of my favourites.
• Do not over-mix! A big reason muffins don’t rise or turn out tough is because the batter is over-mixed. Once you see no flour streaks, stop mixing.
• Use large-flake oats. This will give you the best texture of muffin.

FAQ

Do I have to add milk?

Yes! This is one of the main wet ingredients in this recipe. You can use dairy or non-dairy milk such as almond milk.

Do I have to add oats?

Yes! For a classic chocolate chip muffin recipe, check out The Best Chocolate Chip Muffins.

Why do you do 2 temperatures?

The first temperature is a short-term high temperature. The goal here is that the heat is so hot it activates the leavening agents so the muffins grow tall quickly within the first 5 minutes and you get that muffin dome. Then, once you lower it down, it continues to bake inside.
