Snickerdoodle Cupcakes with Streusel
and Cinnamon Frosting

• 3 TBSP unsalted butter - melted

Frosting

• 3 cups confectioners' sugar
• 1 cup unsalted butter, room temperature
• 2 tsp vanilla extract
• 2 tsp ground cinnamon
• 2 TBSP milk (optional)

Directions

Cupcakes

1. Preheat oven to 350 degrees. Line standard muffin/cupcake tin with paper or foil liners. 
2. In a large mixing bowl, whisk together flour, sugar, baking powder, and salt. Add butter, sour cream, egg and egg yolks, and vanilla. Use an electric mixer to beat at medium speed until smooth and satiny, about 30 seconds. Scrape down sides of bowl with rubber spatula and mix by hand until smooth and no flour pockets remain. 
3. To prepare streusel, combine the brown sugar, flour and cinnamon in a medium bowl. Pour melted butter over the mixture and use a fork to combine and crumble.
4. Place a tsp of the streusel in each cupcake liner. Using a heaping TBSP, distribute batter evenly over streusel. Bake until cupcake tops are pale gold and toothpick or skewer inserted into center comes out clean, 20 to 24 minutes. Use skewer or paring knife to lift cupcakes from tin and transfer to wire rack; cool cupcakes to room temperature, about 45 minutes before frosting.

Frosting

1. Beat butter for a few minutes with an electric mixer with on medium speed. Add 2 1/2 cups of powdered sugar and turn your mixer on the lowest speed (so the sugar doesn’t blow everywhere) until the sugar has been incorporated with the butter. Increase mixer speed to medium and add vanilla extract and cinnamon. Beat for 3 minutes. 
2. If your frosting needs a more stiff consistency, add remaining sugar. If your frosting needs to be thinned out, add milk 1 TBSP at a time.
3. Frost each cooled cupcake with a small offset spatula or a pastry tip and bag.
