Instructions

• Start by melting your butter in a medium saucepan over medium heat, watch it bubble without burning.
• Stir in brown sugar and vanilla extract till you get a smooth, sweet sauce.
• Take your pan off the heat and fold in the peanut butter, mix till it's melting and smooth.
• Pour in quick cooking oats, mix till oats are fully coated and sticky.
• Gently fold in your chocolate chips, try not to melt them too much here.
• Press this mix into a greased 9x13 inch baking dish so it sets up nice and firm.
• Transfer that dish into your pressure cooker, place on a trivet so it doesn't touch water. Seal the lid, cook under high pressure for 10 minutes, then do a quick release carefully. Cool with a natural release for 5 minutes before chilling for 30 mins to firm up.
