Ingredients You’ll Need

For the Oat Base

1 teaspoon pure vanilla extract
3 cups rolled oats

For the Chocolate Layer

1 cup chocolate chips (semi-sweet or milk chocolate)
½ cup peanut butter (optional, for extra creaminess)

Step-by-Step Instructions

Step 1: Prepare the Oat Mixture

In a medium saucepan, melt the butter over medium heat.
Stir in the brown sugar and vanilla extract, mixing until the sugar dissolves.
Add the rolled oats, stirring continuously for 2-3 minutes until well coated.

Step 2: Press the Oats Into a Pan

Line an 8×8-inch or 9×9-inch baking dish with parchment paper.
Press half of the oat mixture firmly into the bottom of the dish.
Reserve the other half for topping.

Step 3: Melt the Chocolate Layer

In a microwave-safe bowl, combine the chocolate chips and peanut butter.
Microwave in 30-second intervals, stirring each time, until smooth and fully melted.
Pour the melted chocolate mixture over the oat layer, spreading evenly.

Step 4: Add the Final Oat Layer

Sprinkle the remaining oat mixture over the chocolate, pressing it down gently.
(Optional) Add extra chocolate chips or oats on top for decoration.

Step 5: Chill Until Set

Refrigerate for at least 2 hours (or freeze for 30 minutes) until firm.
Once set, lift the bars from the pan and cut them into squares.

Step 6: Serve & Enjoy!

Serve cold or at room temperature.
Store leftovers in an airtight container in the fridge for up to 1 week.

Tips for the Best No-Bake Chocolate Oat Bars

🔹 Use Old-Fashioned Oats – They hold up better than quick oats, giving a chewy texture.
🔹 Press the Oats Firmly – This helps the bars hold their shape when slicing.
🔹 Refrigerate Long Enough – Let them set for at least 2 hours to prevent crumbling.
🔹 Use High-Quality Chocolate – Better chocolate = richer flavor!
🔹 Make It Healthier – Swap butter for coconut oil and brown sugar for honey or maple syrup.
