- 1 teaspoon vanilla extract
- 3 cups quick-cooking oats

How to Make No-Bake Chocolate Peanut Butter Oat Bars
1. Prepare the Pan
Line an 8- or 9-inch square baking pan with parchment paper, leaving some overhang on the sides. This makes the finished bars much easier to lift out and slice.
2. Make the Oat Mixture
Add the butter, brown sugar, and granulated sugar to a saucepan over medium-low heat.
Stir frequently as the butter melts and the sugars dissolve. Bring the mixture to a gentle simmer and cook for about 2 minutes, stirring constantly.
Remove the saucepan from the heat and stir in the vanilla and salt.
Add the quick oats and mix thoroughly until every oat is coated in the buttery mixture.
