For the peanut butter layer use the same food processor without cleaning to make things easy!
1/2 c. almonds
1/4 c. walnuts
3/4 c. raisins
1/2 c. oatmeal
1/2 c. peanut butter (no sugar please)
Grind nuts, raisins and oatmeal in the food processor until crumbly. Add peanut butter and whiz until mixture comes together and can hold its shape. Set aside.
