These Chocolate Sour Cream Sugar Cookies are super soft and smothered in chocolate cream cheese frosting -- it's everything a chocolate cookie should be! Includes a step by step recipe video.
In a large bowl with an electric mixer, beat butter and sugar on high until combined.
Add sour cream, eggs and vanilla, and beat until smooth.
Add flour, cocoa, baking soda and baking powder and beat on low until combined -- dough will be soft, almost like thick cake batter. Do NOT add flour.
Preheat oven to 350 degrees F and line baking sheets with parchment paper. Drop by heaping tablespoonfuls (or a 2 TBSP cookie scoop) onto baking sheets 2-3 inches apart and bake for 9-11 minutes, until edges are golden and centers are set.
Make the frosting:In a small microwave-safe bowl, combine chocolate and cream. Microwave on high in 10-20 second intervals, stirring well each time, until chocolate is melted. Set aside.
In a large bowl, beat cream cheese and butter until smooth. Add the melted chocolate and powdered sugar and beat until smooth and creamy, 2-3 minutes. Spread over cooled cookies and serve or refrigerate to set the frosting. Store in the refrigerator for up to 4 days or in the freezer (I recommend freezing in a single layer before stacking) for up to 3 months.
