  • 1 cup125 gAll-purpose flour
  • ⅔ cup packed130 gBrown sugar

  • ⅔ cup chopped70 gWalnutsroughly chopped
  • ½ tsp1 gGround cinnamon

Steps

  1. Heat the oven to 350°F (175°C) and line an 8-inch square pan with parchment, leaving an overhang.
  2. Melt the butter and let it cool a few minutes while you roughly chop the dry-roasted peanuts and the walnuts.
  3. In a large bowl, whisk the oats, flour, brown sugar, baking soda, salt and cinnamon, then stir in the melted butter until the mixture forms moist clumps.
  4. Divide the oat crumble: press two-thirds of it firmly into the pan for the base, and set the remaining one-third aside for the topping.
  5. Bake the base for 12 minutes, until just set and lightly golden at the edges.
  6. Meanwhile, in a medium bowl, stir the peanut butter, maple syrup and vanilla until smooth, then fold in half of the chopped dry-roasted peanuts and half of the chopped walnuts.
  7. Spread the peanut butter filling gently over the warm base.
  8. Toss the remaining half of the chopped dry-roasted peanuts and the remaining half of the chopped walnuts into the reserved crumble and scatter it evenly over the filling, pressing lightly.
  9. Bake 20 to 22 minutes, until the topping is golden brown and the edges are golden.
  10. Cool completely in the pan on a rack, about 1 hour, so the bars firm up, then lift out by the parchment and cut into 12 bars.
