• 1 cup brown sugar, packed
• 1/2 cup unsalted butter, melted
• 1/4 cup peanut butter
• 1 large egg
• 1 teaspoon vanilla extract

• 2 tablespoons peanut butter (or caramel sauce)

Tools You’ll Need

• Mixing bowls
• Whisk and spatula
• 8×8-inch baking pan
• Parchment paper
• Microwave-safe bowl (for drizzle)

Optional Substitutions & Additions

How to Make

1. Preheat oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper.
2. In a large bowl, combine oats, flour, brown sugar, baking soda, and salt.
3. In a separate bowl, whisk melted butter, peanut butter, egg, and vanilla until smooth.
4. Pour wet ingredients into dry and mix until combined.
5. Press mixture evenly into prepared pan.
6. Bake for 20–25 minutes, or until edges are golden brown.
7. Let bars cool completely in the pan.
8. For drizzle, melt chocolate chips and peanut butter in a microwave-safe bowl in 20-second bursts, stirring until smooth.
9. Drizzle over cooled bars, let set, then cut into squares.

What to Serve With

• Hot coffee or tea for an afternoon snack
• A scoop of vanilla ice cream for dessert
• Fresh fruit for a balanced plate

Tips for Success

• Don’t overbake—the bars will firm up as they cool.
• For cleaner cuts, chill bars before slicing.
• Use parchment with overhang for easy removal from the pan.

Common Mistakes to Avoid

• Overmixing – Can make the bars tough.
• Not cooling before drizzling – Warm bars will melt your drizzle into a mess.
• Using quick oats – Changes texture, making them less chewy.

How to Store & Reheat

• Store in an airtight container at room temperature for up to 4 days.
• Refrigerate for up to 1 week or freeze for up to 3 months.
• No reheating needed, but you can warm slightly for a softer texture.
