How to Make Easy Chocolate Oat Bars

Preheat the oven to 350ºF and line a 13x9 baking dish with parchment paper or aluminum foil.
Combine the softened butter together with the vanilla extract, quick oats, flour, brown sugar, and granulated sugar in a large mixing bowl.
Press all but ½ cup of the mixture evenly into the prepared pan.
Bake for 10-12 minutes and remove from the oven.
Pour the can of sweetened condensed milk over the baked oat layer.
Mix the crushed peanuts together with the chocolate chips in a medium bowl and spread half of the mixture in an even layer on top of the condensed milk.
Sprinkle the remaining oat mixture on top and top with the remaining chocolate chips and peanuts.
Press the mixture down into the condensed milk layer evenly.
Bake bars for 25 to 30 minutes.
Remove from the oven and let the baking dish cool completely before slicing.

Quick Tips for Perfect Chocolate Oat Bars

Use quick cooking oats in place of old fashioned oats for a softer and chewier texture and better binding.
Press the bottom layer firmly into the pan so it holds its shape after baking.
When layering, spread the condensed milk evenly to avoid overly gooey or dry patches.
Allow the bars to cool completely before slicing-this helps them set properly.
For clean cuts, use a sharp knife dipped in hot water and wipe between each slice.

How to Store Chocolate Oat Bars

Once cooled and cut, these chocolate chip oat bars can be stored in an airtight container at room temperature for up to 5 days. For longer storage, layer them with parchment paper in a freezer-safe container and freeze for up to 2 months. Simply thaw at room temperature before serving for that perfect chewy bite.
