Ingredients you’ll need

Here’s a list of ingredients you’ll need to make these bars. You can find my recipe card at the bottom of this post for the complete list with their amounts.

  • Smooth peanut butter
  • Honey: If you can’t get hold of honey, you can use maple syrup, golden syrup or light corn syrup.
  • Rolled oats: Quick porridge oats work fine too.

Optional: You can add a few chocolate chips to the mixture, or even drizzle on some melted chocolate once cut into bars.

How to make No-Bake Peanut Butter Oatmeal Bars

To make these bars, simply grab a large microwave-safe mixing bowl and add the peanut butter and honey.

Heat in 20 second intervals until the peanut butter is runny and can be combined easily with the honey.

Add the oats and fold in until incorporated. If using chocolate chips, add now.

Press the mixture firmly into an 8×8-inch square baking pan lined with parchment paper or foil.

Cover and refrigerate for at least 1 – 2 hours (or freeze for 30 minutes to 1 hour) before removing and cutting into bars. You can either cut into 8 long bars (as pictured), or 16 square bars.

Once cut into bars, drizzle them with melted chocolate if desired.

NOTE: For best results, I highly recommend using the gram measurements (with a digital scale), rather than the cup measurements.

Cup measurements are simply not accurate enough, and I cannot guarantee the best results if you use them.

How should one adjust the above recipe if looking to add into the mix Brewed Cacao (e.g. roasted grounded Cacao beans typically used as coffee alternative)?

And can other Nut Butters like Walnut, Pecan, Macadamia and Pine Nuts be used in same amount as Peanut Butter or does one have to account for how thick / runny they may be?

Hi Marsha Love how easy this recipe is! Do you think it would work ok if I only used half the amount of honey, as I'm trying to eat healthier and cut down on the amount of sugar I'm consuming? Or could I use a sugar substitute such as monkfruit? Thanks, Heather

Hi Heather! You could try using a little less (about 1/4 cup less), but not too much as it helps combine everything together along with the peanut butter.
