How to Make No-Bake Chocolate Oat Bars (Step-by-Step)

Step 1 — Make the Oat Base

In a medium saucepan, melt the butter and brown sugar over medium heat. Cook until the sugar dissolves. Remove from heat and stir in vanilla. Add oats and mix until fully coated.

Step 2 — Press Into the Pan

Line a baking pan with parchment. Press about ⅔ of the oat mixture into the bottom.

Step 3 — Make the Chocolate Layer

In a microwave-safe bowl, melt the chocolate chips and peanut butter together in 30-second intervals, stirring until smooth.

Step 4 — Layer It Up

Pour the chocolate mixture over the oat base and spread evenly. Crumble the remaining oat mixture over the top.

Step 5 — Chill

Refrigerate for 2–3 hours, or until set.

Step 6 — Slice and Enjoy!

Cut into bars and try not to eat the whole batch. (Good luck!)
