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.

The printable recipe card with the full list of ingredients, their measurements, and instructions can be found at the bottom of this post.

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.
