These Cinnamon Oatmeal Streusel Muffins are perfect for breakfast. They are fluffy muffins with oats and cinnamon in every bite! The muffins are sprinkled with an oatmeal sugar streusel that crisps up in the oven, creating the perfect muffin top. You will love these muffins.
In a medium sized bowl, add flour, white sugar, dark brown sugar, cinnamon, rolled oats, and softened butter. Using your hands, mix this until crumbly and combined. Set in the refridgerator while you make the muffin batter.
1/2 cup all-purpose flour, 4 tbsp butter, 1/4 cup white sugar, 2 tbsp dark brown sugar, 1/4 cup large flake oats, 1/2 tsp cinnamon
For the muffins
Preheat the oven to 375℉/190℃. Line a muffin tin with 12 liners and set aside.
In a medium-sized bowl, add in flour, cinnamon, cloves, oats, salt, cornstarch, baking powder, and baking soda. Using a spatula, mix until combined. Set aside.
In another large bowl, whisk oil, eggs, milk, vanilla, sour cream, white sugar, and brown sugar. Whisk until well combined.
1/2 cup dark brown sugar*, 1 tbsp vanilla, 2/3 cups oil, 2 large eggs, 3/4 cups full-fat sour cream, 1/2 cup milk, 1/3 cup white sugar
Add the dry ingredients into the wet. With a spatula, gently fold just until a soft muffin batter forms. Don't over-mix.
Evenly divide the batter between the liners. Sprinkle a handful of streusel on top.
Bake the muffins at 375°F for 25-30 minutes. The muffins are ready when a toothpick inserted comes out dry with no wet batter.
Allow to cool, and enjoy! These muffins are so delicious!
Notes
*Brown sugar - This recipe is not meant to be sweet, it is more of a breakfast-style muffin. If you are looking to sweeten them up, add in 1/4 cup (50g) more of brown sugar.
