    These muffins are so dang good! They have sweet apples inside each bite.

    The muffins come together in a few easy steps with simple ingredients. Let's get to baking!

    Ingredients Notes

    Check out this section to see some key ingredients used in this recipe.

    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 – Used to enhance the texture.

    Cinnamon - Adds a lot of depth to the flavour! I also used a pinch of nutmeg and cloves.

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

    Oil – You can use any type of oil.

    Oats - Make sure to use rolled oats or large flake oats.

    Sour Cream – The secret ingredient that makes these muffins amazing.

    Step by step instructions

    Here is how to make and bake these Apple Oatmeal Streusel 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 and set aside. I used tulip liners, which result in a taller muffin and makes 9 muffins total. Shred one apple and cut the second apple into small cubes.

    Step 2 – Make the streusel. In a medium sized bowl, add flour, white sugar, brown sugar, oats, cinnamon, and softened butter. Using your hands, mix this until crumbly and combined. Set aside while you make the muffin batter.

    Step 3 – Mix together dry ingredients. In a medium-sized bowl, add in the dry ingredients. Using a spatula, mix until just completely combined.

    Step 4 – Whisk wet ingredients. In a large bowl, whisk oil, eggs, milk, vanilla, sour cream, and brown sugar. Whisk together for 2-3 minutes until smooth.

    Step 5 - Combine dry and wet ingredients. Mix together with a spatula until a soft muffin batter forms.

    Step 6 - Add in apples. Mix in the shredded and diced apples until evenly distributed amongst the batter.

    Step 7 – Scoop. Evenly divide the batter between 12 liners in regular liners, they should all the way full. If using tulip liners, you will have 10 liners filled halfway. Sprinkle a handful of streusel on top of each muffin.

    Step 8 – Bake. Bake the muffins at 375°F for 20-28 minutes in regular liners, and 30-35 minutes in tulip liners. The muffins are ready when a toothpick inserted comes out clean.

    FAQ

    How do I store these muffins?

    These muffins are best served fresh. They stay fresh at room temperature for up to 3 days, and in an airtight container in the refrigerator for up to 5 days.

    Do I have to add sour cream?

    Yes! This is one of the main ingredients in this recipe. You can also substitute sour cream for room temperature full-fat yogurt or buttermilk.

    Do I have to add oats?

    Yes!
