1Heat oven to 350°F. Spray 13x9-inch pan with cooking spray (without flour).
2In medium bowl, mix oats, flours, baking powder, baking soda and 3/4 cup of the peanuts with whisk; set aside. In large bowl, beat butter, sugar and peanut butter with electric mixer on medium speed until blended. Beat in eggs. Gradually add oat mixture, beating on low just until combined.
3Press two-thirds (about 3 1/2 cups) of the dough in pan. Spread jam over crust. Drop heaping spoonfuls of remaining dough over jam. Sprinkle with remaining 1/4 cup peanuts.
4Bake 25 to 30 minutes or until set and golden brown. Cool in pan on cooling rack 1 hour. Refrigerate 30 minutes. Cut into 6 rows by 4 rows. Store in refrigerator.
