Preheat oven to 350°F. Grease a 8X8" baking pan. Set aside.
In a large saucepan melt butter with 1 cup chocolate chips. Stir until smooth. Add sugar and cocoa powder. Mix well. Set aside to cool slightly, about 10 minutes, stirring occasionally.
To the chocolate mixture add lightly beaten eggs and vanilla. Stir vigorously, then add almond flour, baking powder, and salt. Mix well.
Stir in remaining ¼ cup chocolate chips. Pour into prepared baking pan and spread evenly. Bake for 30-35 minutes, or until toothpick inserted in middle comes out clean. Cool in pan on wire rack before slicing and serving.
