Ingredients

• 1 cup (2 sticks) butter
• 1/2 cup packed brown sugar
• 1 teaspoon vanilla extract
• 3 cups quick-cooking oats
• 1 cup semisweet chocolate chips
• 1/2 cup creamy peanut butter

Instructions

1. Prepare the oat base:

• Melt butter in a large saucepan over medium heat.
• Stir in brown sugar and vanilla until dissolved.
• Remove from heat and mix in oats until fully coated.

1. Press the base:

• Line a 9×13-inch baking pan with parchment paper.
• Press 2/3 of the oat mixture firmly into the bottom of the pan.

1. Make the chocolate layer:

• In a microwave-safe bowl, combine chocolate chips and peanut butter.
• Microwave in 30-second intervals, stirring until smooth (about 1-2 minutes total).

1. Assemble the bars:

• Spread chocolate mixture evenly over the oat base.
• Crumble remaining oat mixture over the top, pressing lightly.

1. Chill and serve:

• Refrigerate for at least 2 hours until firm.
• Cut into bars and store in an airtight container.

Tips

• For firmer bars, use quick oats; for chewier texture, use old-fashioned oats
• Add 1/4 teaspoon salt if using unsalted butter
• Substitute almond butter for peanut butter if desired
• Bars keep well in refrigerator for 1 week or freezer for 2 months

These rich, chewy bars require no baking and make a perfect easy dessert or snack. The combination of oats, peanut butter, and chocolate creates a satisfying treat that’s both simple to make and delicious to eat.
