Cinnamon Streusel Muffins are one of my favorite dessert breakfasts! They're like sour cream coffee cake muffins with cinnamon streusel topping. These are perfect to grab when you're on the go! And by "on the go", I mean running from your kitchen to your office because you're late for a Zoom meeting…
I like to wash these down with a glass of milk, but they also go great with a cup of coffee or tea! My favorite thing about these muffins is that they have crumbly layers of cinnamon sugar swirled in the middle! It's such a delicious surprise and makes them seem like more of a fancy bakery muffin, almost like a cinnamon roll in muffin form! However, they're really so easy to make!

- All purpose flour
- Baking soda
- Baking powder
- Sour cream: full-fat is best in this recipe to make sure they're soft and fluffy!
- Unsalted butter
- Vanilla extract
- Buttermilk: If you don't have any on hand, you can replace this with kefir or mix ¼ cup of milk with ¾ teaspoon of vinegar or lemon juice and then let it sit for a few minutes to curdle slightly. The acidity adds a nice tangy flavor and weakens the gluten, yielding softer muffins!
- Light brown sugar
- Granulated sugar
- Ground cinnamon
See recipe card below for quantities.

Step by Step Instructions
Step One (Picture 1 above) - Melt the butter and mix in the flour, light brown sugar and cinnamon. It will dry up into a crumbly mixture while you make the muffin batter.
Step Two (Picture 2 above) - In a large bowl, cream together the butter and sugar until its light and fluffy (about 3 minutes). Stir in the eggs, vanilla extract and sour cream.
Step Three (Picture 3 above) - In a medium bowl, whisk together the flour, baking soda, baking powder and salt. Alternately stir the dry ingredients and buttermilk into the wet ingredients just until combined.
Step Four (Picture 4 above) - Scrape down the sides of the bowl as needed so that everything gets mixed together. The batter will be fairly thick.
Step Five (Picture 1 above) - Drop about 1 teaspoon cinnamon streusel crumbs into the bottom of each muffin liner. Follow it up with about a tablespoon of muffin batter.
Step Six (Picture 2 above) - Add 2 teaspoons of streusel and then more batter until the liner is about ¾ full. Cover with more streusel. Feel free to sprinkle a little turbinado sugar (or demerara sugar) on the tops for an extra sweet crunch!
Bake the cinnamon streusel muffins at 350°F until a toothpick inserted in the center comes out clean (about 13-18 minutes). Let them cool in the muffin tin for a few minutes and then carefully transfer them to a wire rack.
Streusel is a crumbly topping usually made of flour, sugar and a fat. In this recipe, it's made of flour, brown sugar, butter and cinnamon.
This could be from over-measuring the flour. I always recommend using a food scale to weigh it in grams (see "metric" in the recipe card below) for the most accurate measurements. Scooping and leveling in measuring cups is the next best method. Another reason could be if your oven has the convection setting on.
This could be from inaccurate measuring (more liquid or less dry ingredients than required). It could also be from overmixing the batter.
This recipe should give you about 12 delicious cinnamon crumble muffins!
Room Temperature: You can continue to enjoy these cinnamon muffins with streusel topping for 2-3 days after baking if they're stored in an airtight container.
Freezing Instructions: Make sure the cinnamon muffins have cooled completely and then cover them tightly in plastic wrap and a freezer-safe bag. Store them in the freezer for up to 1 month. Don't forget to write "Cinnamon Streusel Muffins" and the date on the bag! When you're ready to enjoy them, heat them in the microwave for 30-60 seconds. This is a great way to have a quick breakfast always on hand!
Cinnamon Streusel Muffins
- Muffin pan
- Mixing bowls
- Measuring spoons
- Hand mixer optional
- 8 tablespoons unsalted butter melted
- 1½ cups all-purpose flour
- ¾ cup light brown sugar packed
- 1½ tablespoons ground cinnamon
- ¾ cup unsalted butter room temperature
- 1 cup granulated sugar
- 2 large eggs room temperature
- 2 teaspoons vanilla extract
- ⅔ cup sour cream room temperature
- 2 cups all-purpose flour
- ½ teaspoon baking soda
- 1½ teaspoons baking powder
- ½ teaspoon salt
- ¼ cup buttermilk *see notes below
- Mix together the flour, brown sugar, and cinnamon. Melt the butter and stir it into the mixture. Let it sit and dry out while making the batter.
- Preheat oven to 350°F and line a cupcake pan with liners (or spray with oil if you don't have liners).
- In a large bowl, cream together the butter and sugar until light and fluffy (~3 minutes). Add the eggs, one at a time, followed by the vanilla and sour cream. Mix well.
- In a separate bowl, whisk together the flour, baking soda, baking powder, and salt.
- Gently stir half of the dry ingredients into the wet ingredients, then mix in the buttermilk. Add the remaining dry ingredients and mix until only a few flour streaks are visible. The batter will be pretty thick.
- Pour 1 teaspoon of the cinnamon streusel into the bottom of each cupcake liner. Then, add a tablespoon of muffin batter over the top of it, followed by 2 teaspoons of streusel. Repeat until the muffin liner is about ¾ full. Try to spread the batter out so it's smooth and then finish by covering the tops completely with streusel. (Optional: sprinkle a little turbinado sugar on the tops too!)
- Bake for 13-18 minutes or until the tops are lightly tan and a toothpick inserted in the center of one comes out clean.
- Allow the muffins to cool in the pan for 5-10 minutes, and then carefully transfer them to a cooling rack.
