  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 1/3 cup oil , canola or vegetable
  • 1 cup granulated sugar

  • 1/4 cup sour cream
  • 1/4 cup milk

Chocolate Frosting

  • 1 cup unsalted butter , softened
  • 2/3 cup cocoa powder , sifted
  • 1 tsp vanilla extract
  • 1/4 tsp salt
  • 3- 3.5 cups powdered sugar

Instructions

Mini Chocolate Cupcakes

  • Preheat the oven to 350F degrees. Line mini muffin pans with mini muffin papers.
  • In a medium bowl whisk together the flour, cocoa, baking soda, baking powder, and salt.
  • In a separate large bowl whisk together the oil, sugar, eggs and vanilla extract. 
  • Whisk in the sour cream and milk
  • Carefully whisk the dry ingredients into the wet ingredients. 
  • Spoon the batter into the prepared mini muffin pan filling each about 1/2 to 2/3 full. Be careful not to fill more than 2/3rds.
  • Bake in the preheated oven for 10-13 minutes or until the tops are no longer shiny and slightly firm to the touch.

Chocolate Frosting

  • In a large bowl beat the butter until no lumps remain.
  • Mix in the cocoa powder, vanilla extract and salt.
  • Mix in the powder sugar about 3/4-1 cup at a time, alternating with 1 tablespoon of cream/milk until the desired consistency and sweetness level is reached.
  • Frost the cupcakes with a knife or piping tip and bag (I used a 1M tip).

Notes
