Buckeye Brownies. An easy brownie bar, swirled with a delicious peanut butter filling! These were delicious! I had to cook longer than the 25 mins and they were still really soft. I used applesauce instead of the oil to make it a little more healthy. I also omitted the peanuts as Dan and I both don't like nuts in our desserts. I got lots of compliments at the GC graduation party.
