Instructions

Prepare the pan

Line a 20 cm (8-inch) square baking dish with parchment paper, leaving some overhang for easy removal.

Melt butter and sugar

In a medium saucepan over medium heat, melt the butter and brown sugar together, stirring until the sugar is dissolved.

Add vanilla and oats

Remove from heat and stir in the vanilla extract. Add the oats and mix until well-combined.

Press oat mixture into pan

Press half of the oat mixture firmly into the prepared pan to form an even layer.

Pro tip: Use the back of a spoon to evenly press and smooth the mixture.

Prepare chocolate layer

In a microwave-safe bowl, combine chocolate chips and peanut butter. Microwave in 30-second intervals, stirring after each, until melted and smooth.

Layer chocolate and remaining oats

Pour the chocolate mixture over the oat layer in the pan, spreading evenly. Scatter the remaining oat mixture over the chocolate layer, pressing gently.

Chill the bars

Refrigerate for about 1 hour, or until the bars are firm and set.

Pro tip: For quicker setting, place in the freezer for 30 minutes.
