This is my teen’s top favorite peanut butter bar recipe. This 6 ingredient, preservative free recipe, is fast, super easy to make, and yields delicious and healthy peanut butter oatmeal bars with just the right amount of sweetness. These make the perfect lunchbox or quick treat, I make a batch of these every week. A baking sheet lined with parchment paper can hold a single or double batch of these uncut bars. The whole batch, baking sheet and all, can be stored in the refrigerator or freezer (I usually keep mine in the freezer). For convenience, place a cutting tool in the pan to cut out squares or bars whenever needed. If anything like my household, these bars will be eaten too often to keep getting a new knife each time a piece is cut. The great thing is you can cut as big or small a piece as you are in the mood for. Often times when I am at home a small sliver satisfy my sweet tooth. For lunchboxes treats, I usually cut the bars into a traditional granola bar size.
1/2 cup milk
1/2 stick butter, 4 oz. (4 TBLS)
1 cup sugar
1 tsp vanilla
1 cup natural creamy peanut butter (try to find a version with peanuts and salt only)
3 cups old fashioned oats uncooked
In a large sauce pan heat the milk, butter, and sugar till boiling and then continue to boil for two minutes, the mixture will foam a bit. Turn off the heat. Add the peanut butter and vanilla and stir till combined. Add the oats and stir till just combined. Turn onto a sheet pan and spread out to desired thickness, we usually spread out to granola bar thickness. Freeze directly on the baking sheet or refrigerate until set, approximately 1 hour. Cut into bars when firm and enjoy! Bars keep well in the freezer and taste great on a hot day or when the sweet tooth hits you!
