Warm, cozy, and filled with cinnamon - these spice cake cupcakes with cinnamon cream cheese frosting are perfect for fall. You'll love the soft cupcake crumb and extra creamy buttercream.
In a large bowl beat the butter and sugars until fluffy (about 2 minutes).
1/2 Cup Unsalted Butter, 3/4 Cup Packed Brown Sugar, 1/4 Cup White Sugar
Mix in the eggs 1 at a time, followed by the vanilla.
2 Large Eggs, 2 teaspoons Vanilla Extract
In a liquid measuring cup or small bowl, whisk together the buttermilk and sour cream.
1/3 Cup Buttermilk**, 1/3 Cup Sour Cream
With the electric mixer on low speed, beat in about 1/3 of the flour mixture followed by about 1/3 of the buttermilk and sour cream mixture. Turn off the mixer and scrape down the sides of the bowl as necessary. Repeat the process, alternating between additions of flour and buttermilk.
Spoon the batter into the prepared muffin pan, filling each about 2/3 full.
Bake in the preheated oven on the middle rack for 16-18 minutes, or until the tops feel slightly firm to the touch and an inserted toothpick comes out clean.
Cinnamon Cream Cheese Frosting
In a large bowl, beat the butter until fluffy (about 2 minutes).
2/3 Cup Unsalted Butter
Then mix in the cream cheese until just combined.
3 oz Brick-Style Cream Cheese
Add in the cinnamon and vanilla extract, then beat in 2 cups powdered sugar starting with the mixer on low speed.
Mix in the rest of the powdered sugar about 1/2 cup at a time, going slowly until the desired sweetness is reached.
If the frosting seems too thick, beat in 1-2 tablespoons of cream.
1-2 Tablespoons Cream
Transfer the frosting to a piping bag, and frost. Or frost with a knife.
