Mix all dry ingredients together, then add nonfat milk and vanilla to blend flavors.

Add peanut butter and mix together well with hands.

After mixed, put mixture in an 8" by 8" pan. You can line the pan with wax paper for easy removal later.

Place plastic wrap or wax paper on top of mixture and push evenly into pan to flatten.

Refrigerate for 3 hours, then cut into squares.
