These Healthy Small Batch Peanut Butter Bars are made with just 4 ingredients and no baking required! Made with natural peanut butter, oats and honey. A healthier version of traditional peanut butter bars. The "frosting" is made with cream cheese and lightly sweetened with a touch of honey.

How To Make Peanut Butter Bars

Oats, peanut butter and honey make up the bottom layer of the peanut butter bars. These ingredients are mixed together and pressed into the bottom of a small baking dish.

Peanut butter, oats and honey are also in the second layer. This time, the oats are ground in a food processor or a blender to create an oat flour and mixed with the peanut butter and honey. Graham cracker crumbs are the traditional binder used in many versions of peanut butter bars but instead of using graham cracker crumbs, I use oat flour instead.

There are only two ingredients in the top layer of “frosting”. I use just cream cheese and honey. These ingredients are blended together and spread over the middle layer.

After the layers are assembled, place the bars in the refrigerator to chill.

Best Dish To Use When Making Peanut Butter Bars

For this peanut butter bars recipe, I use a 5-inch baking dish. Use a dish of similar size for best results. You can also use a few small ramekins and create small, individual deep dish peanut butter bars or use a loaf pan for thinner layers. This recipe will give you around 4 to 6 bars depending on the size of dish you use.

How Long Will Peanut Butter Bars Last?

They will keep well in the refrigerator for a week.

  • 1/2 cup natural peanut butter
  • 1/4 cup honey
  • 6 tablespoons oat flour *See Notes


  • 2 ounces cream cheese , softened

To make oat flour, place oats in a food processor or a blender and pulse or blend to ground to a powdery, flour-like consistency.
