Chocolate Truffle Cookies

4 oz unsweetened chocolate
2 C semi-sweet chocolate chips, divided
1/3 C butter
1 C sugar
3 eggs
1 1/2 tsp vanilla
1/2 C flour
2 tbsp unsweetened cocoa powder
1/4 tsp baking powder
1/4 salt
powdered sugar for rolling

In a large saucepan over low heat, melt the unsweetened chocolate, 1 cup of the chocolate chips, vanilla, and butter together; stirring, until smooth ( I do this in the microwave on 50% power). Remove pan from heat; cool for 10 minutes.

In a large bowl, beat the eggs and sugar together for 2 minutes with an electric mixer on medium speed. Beat in the vanilla and chocolate mixture.Combine the flour, cocoa powder, baking powder, and salt; add to the chocolate mixture just until combined. Stir in the remaining chocolate chips.

Chill in freezer for 20-30 minutes.

Roll into 1" balls and dredge in powdered sugar. Place 2" apart on ungreased or parchment paper-lined cookie sheets.Bake in a preheated 350*F.oven for 10-12 minutes, or until lightly puffed and set. Cool for 3-4 minutes on the cookie sheets before removing to a wire rack; cool completely.
