These are quintessential bake sale cookies. This recipe will give you those beautiful 4-inch cookies you see at the bakery section of your grocery store. They are great for holidays because you can purchase the special holiday colored M&Ms. The recipe only makes 18 cookies, but I have doubled and even tripled it with success. If you decide to make multiple batches at one time then you will need to break out the big Kitchenaid mixer!!
- Preheat oven to 325°F.
- Beat butter, sugar, and egg in a large bowl.
- Stir in 1 cup of melted white chocolate chips.
- Mix in flour, baking soda, and cream of tartar.
- Stir in M&Ms and 1 cup of white chocolate chips.
- Shape dough into 2-inch balls. Place about 2 inches apart on an ungreased cookie sheet. Flatten them slightly with your hand.
- Bake 15-18 minutes, the cookies will not get very brown, but do not over bake.
- Remove from cookie sheet and cool completely on a wire rack.
- If desired drizzle with 1/2 cup of melted white chocolate chips. (Please don't skip this step, the melted chocolate drizzle gives them the perfect finishing touch!).
Beautiful! I took these to a Valentine's cookie exchange party and they complemented the other contributions which were mostly regular chocolate. I didn't need to bake them the full 15 minutes. This dough is hard and a little frustrating to work with in the food processor and also getting the M&Ms to stick in it, but the final result is worth it.
I have made this recipe for almost 20 years. I found it in a Betty Crocker Contest Winner Cookbook. It is always a hit. I dip one edge of the cookie in the 1/2 cup of melted vanilla chips and drizzle it with 1/3 cup of melted semi-sweet chocolate chips.
