Ingredients for No Bake Peanut Butter Bars

As mentioned above this recipe only takes 5 simple, wholesome ingredients, things you probably already have at home in your pantry. Here is what you will need for this recipe:

  1. creamy peanut butter: creamy peanut butter is best to give these granola bars a smooth texture, now you can substitute crunchy peanut butter if you prefer, or if that is what you have on hand, it will just add a little bit more texture to this recipe. Note: some natural peanut butters will not work in this recipe. If your peanut butter is already runny, don’t use it for these peanut butter bars, it won’t set up.
  2. oatmeal: good old fashion oats are what we use for this recipe, quick oats can be used as a substitute if needed.

  1. vanilla: I like to use a good Mexican vanilla like this one. Vanilla extract just doesn’t have as much flavor, but of course, use what you have available.
  2. honey: that sweet, sweet honey is going to give this peanut butter treat a sweet taste
  3. semi-sweet chocolate chips: mixed with a little peanut butter, these make the perfect topping for these oatmeal bars

How to make Peanut Butter Bars

First, to make these peanut butter oatmeal bars with chocolate, start by placing the peanut butter into a large mixing bowl. Microwave in 30 second increments, until smooth. This only took about 1 minute in my microwave.

Carefully, take out the peanut butter from the microwave and stir in the honey and vanilla until smooth.

Next, stir in the oatmeal and make sure to get everything well coated. Be sure to scrape the sides and bottom of the bowl to get all of the peanut butter mixture combined with the oats to make a creamy oat mixture.

Press the oat mixture into the bottom of a well greased 8 x 8 inch baking dish. While that is setting, get to work on the chocolate topping.

Lastly, for the chocolate topping, in a medium sized microwave safe bowl combine the chocolate chips and peanut butter. Adding the peanut butter will help keep the chocolate softer after it has chilled and not leave a crunchy chocolate topping.

Microwave the chocolate for 30 seconds, take out and stir until smooth. If your chocolate is still not warm enough to mix, microwave in tens second increments until you can stir it smooth. Don’t go too long, the chocolate can burn.

After the chocolate topping has melted, spread it evenly over the top of the peanut butter bars. Place the bars into the refrigerator for at least 30 minutes, to allow the chocolate to cool and set.

    1. Interesting, did you allow them to cool completely before digging in? I usually let them sit in the fridge for a while until the chocolate is firm and the peanut butter is hardened. We even leave them on the counter afterward and they still hold their shape. Not sure what went wrong.

  1. 3 stars
    These taste delicious but I couldn’t get them to bind despite melting peanut butter in microwave and mixing thoroughly and chilling for an hour. I was disappointed hoping to have an easy to transport afternoon snack.
