Description
Coffee Cake Muffins take the best of both world and collide them into one delicious breakfast treat. Coffee cake streusel is blended right into the muffin batter and then the batter is topped with more struesel before baking. You'll absolutely love how they turn out but be careful! They will go SO FAST!
Ingredients
For the muffins:
- 3/4 cup sour cream (light is fine)
- 1 large egg
- 1 tsp vanilla extract
- 1/4 cup old fashioned oats
- 1/4 cup (1 3/4 oz) packed dark brown sugar
- 1 tsp ground cinnamon
- 2 cups (10 oz) all-purpose flour
- 1 cup (7 oz) granulated sugar
- 1 tsp salt
- 8 tbsp (1 stick) unsalted butter, cut into 1/2-inch pieces and softened
- 1 1/2 tsp baking powder
- 1/2 tsp baking soda
For the icing:
- 1 cup confectioners' sugar, sifted
- 2 tbsp water
Instructions
- To make the muffins: Adjust an oven rack to the middle position. Preheat the oven to 350° F. Line a 12 cup muffin pan with paper muffin liners.
- In a 1-cup liquid measuring cup, measure the sour cream then whisk in the egg and vanilla; set aside.
- In the bowl of a food processor fitted with the steel blade, add the oats, brown sugar, and cinnamon. Process in quick pulses (about 10-12) until the oats have broken up some; transfer the mixture to a bowl.
- Return the bowl and blade to the processor and combine the flour, granulated sugar, salt in the bowl with quick pulses. Add the butter over the flour mixture and pulse until the butter is oat-sized, about five 1-second pulses. Carefully remove 1 cup of this mixture from the bowl (try not to remove the bowl from the processor) and stir it into the oat mixture until a lumpy streusel forms.
- Add the baking powder and baking soda to the food processor bowl and pulse them into the flour mixture. Add the sour cream mixture to the bowl and process until the flour is just moistened. Add in ¾ cup of the streusel and pulse until the it is distributed throughout the batter with five 1-second pulses.
- Divide the batter evenly between the muffin cups then sprinkle the remaining streusel evenly over the batter, lightly pressing it down into the batter to ensure it will stick while baking.
- Bake for 18 to 20 minutes, rotating the pan halfway through the time – just a few crumbs should stick to a toothpick when tested in the center of a muffin. Let the pan cool on a wire rack for 5 minutes then transfer the muffins to the rack. Set a piece of parchment or wax paper under the rack.
- To make the icing: In a small bowl, whisk the confectioners' sugar and water together until the sugar is smooth. Drizzle 2 teaspoons of the icing over each of the muffins. Serve warm or at room temperature.

These look divine! I love the idea of coffee cake in muffin form.
Oh my word these look amazing. Much better than the toast I had for breakfast this morning!
I just finished a Starbuck’s muffin while I sit here working… and now I’m terribly unsatisfied 🙂 These look great!
These look scrumptious and the ingredients consist of ALL the flavors I love in a moist and tasty muffin. I like your previous recipe’s flavors, too!
Mmmmmmmm, good!

Yum, I feel exactly the same way about muffins!! And streusel topping? I am always in for that 🙂
Beautiful muffins!
A muffin that leans towards cake (aka cupcakes)? Yes, please! I always feel guilty eating muffins because they’re so big and dense, but making them at home? I’m all about it. And you’ve won me over with the gorgeous drips of frosting and the lovely lighting. Pinning this so I’ll have it when I go to the store and buy sour cream next :]
