Apple Oatmeal Streusel Muffins
Apple Oatmeal Streusel Muffins are so good! They have hearty oats and sweet apple pieces in each bite! Before baking, the muffins are sprinkled with an oat streusel that melts and crisps up on top while baking. Yummy!
Ingredients

- 1 medium-sized apple shredded
- 1 medium-sized apple diced into small cubes
For the streusel
- 1/2 cup all-purpose flour
- 4 tbsp unsalted butter softened
- 1/4 cup white sugar
- 2 tbsp dark brown sugar
- 1/4 cup rolled oats or large flake/old-fashioned oats
- 1/2 tsp cinnamon
Instructions
For the streusel
- 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 aside while you make the muffin batter.1/2 cup all-purpose flour, 4 tbsp unsalted butter, 1/4 cup white sugar, 2 tbsp dark brown sugar, 1/4 cup rolled oats, 1/2 tsp cinnamon
For the muffins
- Preheat oven to 375℉/190℃. Line the muffin tin with 12 liners (or 10 tulip liners) and set aside. Chop one of the apples into small cubes, and shred the other one. Set aside.1 medium-sized apple, 1 medium-sized apple
- In a medium-sized bowl, add in the dry ingredients. Using a spatula, mix until combined. Set aside.1 1/2 cups all-purpose flour, 1 cup rolled oats, 1 tsp baking soda, 1 1/2 tsp baking powder, 1 tbsp cornstarch, 2 tsp cinnamon, 1/8 tsp nutmeg, 1/8 tsp cloves, 1/4 tsp salt
- In another large bowl, whisk oil, eggs, milk, vanilla, sour cream, and brown sugar. Whisk until well combined.3/4 cups dark brown sugar, 1 tbsp vanilla, 1/2 cup oil, 3/4 cups full-fat sour cream, 1/4 cup milk, 2 large eggs
- Add the dry and wet ingredients and with a spatula, gently mix until a soft batter forms.
- Add in the apples and gently mix until evenly distributed.
- Evenly divide the batter between the liners. They will be full in regular liners, and about halfway full if using tulip liners. Sprinkle a handful of streusel on top of each muffin.
- Bake the muffins at 375°F for 20-28 minutes in regular liners, or 30-35 minutes in tulip liners. The muffins are ready when a toothpick inserted comes out clean. I baked mine in tulip liners and they took 32 minutes exactly.
Notes
Apples* - You can use any kind of apples, I just like a tart apple in these muffins to balance the sweetness.
