From the kitchen of Erica Wilson.
Mix all dry ingredients together in a 8x8-inch microwave safe pan (important to use this size pan). Add milk and vanilla extract. Place chunk of butter/margarine in center (leave butter as whole do not chop up). Microwave on high for 2 minutes until bottom of dish feels warm. Stir vigorously and blend in chopped nuts. Put in mold or whatever and chill for 1 hour. Use real butter for best results.
