Keyword: chocolate and peanut butter
Servings: 20 bars

Ingredients

  • 5 oz milk chocolate chips
  • 5 oz semi sweet chocolate chips
  • 2 ½ cups all-purpose flour
  • 1 teaspoon baking powder
  • 1 cup butter, chilled
  • 1 ¾ cup light brown sugar, (not packed)
  • 2 cups rolled oats
  • ½ cup chopped walnuts
  • 1 large egg, beaten
  • 14 oz canned sweetened condensed milk
  • ⅓ cup chunky peanut butter, unsweetened

Instructions

  • Preheat your oven to 350 F/180 C.
  • Prepare a 12 x 8 inch cake pan by spraying with non-stick cooking spray (or rubbing with melted butter). Place a piece of parchment into the pan. Make sure the parchment covers the bottom of the pan and overhangs on the two longest sides. This creates a 'sling' which makes it easier for you to remove the bars from the pan once they are cooled.
  • Tip the flour and baking powder into a large mixing bowl. Give it a stir with a whisk to remove any lumps.
  • Cut the butter into smallish pieces and add to the flour. Rub the butter into the flour using just your finger tips. When the butter and flour combines, you want it to look like bread crumbs.
  • Stir in the sugar, oats and chopped nuts.
  • Remove a quarter of the mix and put it into a separate bowl. Add the chocolate chips to this separate bowl and mix together. Set aside for now.
  • Pour the beaten egg into the remaining mixture until combined, then press firmly into the bottom of your prepared pan.
  • Bake in the preheated oven for 15 minutes.
  • While the bars are baking, pour the condensed milk into a small bowl and mix in the peanut butter until combined.
  • Bring the base out of the oven and pour the condensed milk/peanut butter mixture on top of the hot base. Sprinkle the reserved mix with the chocolate chips over the top and press down lightly.
  • Return the pan to the oven and bake for an additional 20 minutes until golden brown.
  • Let the bars cool completely in the pan, then lift them out, using your parchment paper sling, onto a cutting board. Cut into squares.

Notes

These bars will stay fresh in an airtight container at room temperature for up to 5 days.
