Ingredients

  • 1 1/2 c. Bisquick baking mix
  • 1/3 c. sugar
  • 1 egg
  • 6 oz. thick custard-type vanilla yogurt (Yoplait)
  • 2 Tbsp. oil
  • 1/2 tsp. butter flavoring
  • 1/4 c. fine crumbs made from Girl Scout Thin Mints (I use the food processor for this)
  • 1/4 c. finely chopped walnuts
  • 2/3 c. confectioners' sugar
  • 1 to 1 1/2 Tbsp. milk

Method

  • Preheat oven to 350 degrees. Butter an 8-inch square pan. Combine baking mix, sugar, egg, yogurt, oil, and butter flavoring. Beat until well blended. This will be a thick batter. Spoon about half of the batter into the pan and spread to cover bottom of pan. Combine the cookie crumbs and walnuts and sprinkle over the batter. Drop dollops of the remaining batter on top of the cookie crumbs and carefully spread to connect the dollops of batter. You do not have to cover all the crumbs with the batter. Bake for about 30 minutes or until a toothpick comes out clean when inserted into center of coffeecake. Combine the confectioners' sugar and milk. Beat until smooth. Drizzle over top of coffeecake. Allow to cool slightly before cutting.
