Ingredients
Method
- Preheat oven to 350 degrees Fahrenheit. In the bowl of an electric mixer, combine brownie mix, vanilla, flour, butter and egg. Scoop or form into 1 1/2" balls and place 2" apart on a greased or non stick baking mat lined cookie sheet.
- Bake for approximately 8-9 minutes. If you want the cookies to be flat, press down the dough balls slightly before baking, otherwise they will have a little more dimension. If it looks like the first sheet of cookies in the oven is spreading out too much, add 1-2 Tbsp. more flour to the remainder of the dough.
- Allow cookies to sit on sheets for a few minutes before removing them to a cooling rack to cool completely.
- For the buttercream frosting, cream together all ingredients in the bowl of an electric mixer. Frost a cookie, sandwich with another, and place frosted cookies in the refrigerator so the frosting can set completely.
- After frosting is set, melt chocolate in a tall microwavable container or cup and dip sandwich cookies halfway in it. Place cookies back in the refrigerator so chocolate can set.
Notes
*I'm at high elevation, so it's hard to say exactly how much flour you will need. I used 1/4 cup and that was perfect, but you may need to add one or two tablespoons, depending on your elevation.
*One batch of cookies only makes 12 sandwich cookies, so you'll probably want to double the cookie recipe, but the frosting recipe listed above should be more than enough for a double batch of sandwich cookies.
