Peanut Butter Oat Bars

Hi Guys, I hope you are doing well today. Those who know me, know I am an avid Mountain Bikers. I especially love long rides out in nature where I sometimes don’t see a single person or civilisation for 3-4 hours. Every second Saturday, I grab my mountain bike and fill a Ziploc bag with 3-4 of these delicious Peanut Butter Oat bar’s and set off into the wild.

Recently I shared a picture of these bar’s on Facebook and quite a few of my friends requested the recipe. So, as I am not one to keep a secret recipe. Here it is 🙂

Believe it or not, but Flapjack’s or Oat Bars have been around for a few hundred years. Even Shakespeare refers to Flapjacks in Pericles Prince of Tyre. So apparently they first appeared in literature in the 1600’s. Who would have known?

You can make little cups for Yoghurt Fruit cups with the same recipe!

Line the inside of a muffin tin with batter in the shape of a cup and bake for 15 minutes!

Ingredients for peanut butter honey oat bars

Healthy recipes have a few traits that makes them easy to identify. A low amount of processed sugar, low amounts of salt, low amounts of saturated fats and a high amount of fibre. These peanut butter and oat bars check all the boxes on that list. So here is what you will need.

  • Two Large and Ripe Bananas
  • 2 1/3 Cups of Quick Oats
  • 1/4 Cup of Honey
  • 1/4 Cup of Smooth Peanut butter (use the plain healthy type)
  • 1 Pinch of Salt
  • 200 grams of Dark Chocolate

You will also need the following Kitchen Utensils, please note that the links below contain affiliate links. This has no price impact on you but if you buy via my link, I get a small commission that helps me run the blog:

  • A large mixing bowl
  • A Fork to mash the bananas
  • A Form to shape and bake the oat bars, see the Amazon links below.

Silicon Bar Form

These are the bar’s I have used in my photos.

Spring Form

Before I got the silicon mold I used a spring form and just cut the bars using a long knife.

Muffin Tin

Muffin tins also work great, you can make little round cakes instead of bars.

How to make it!

To make peanut butter oat bars all you need to do is this:

Step 1 – Combine

Start by mashing the bananas with a fork. Add in the pinch of salt, honey and peanut butter and whisk until well combined. Now add in the oats one cup at a time. You might not need the whole amount of cups so go easy and see how thick the batter becomes before adding all the oats.

You want a thick but smooth texture that’s easy to spread in the form.

Step 2 – Form and Bake

It’s time to place the oat, honey, banana batter in to the baking form. If you are using a silicone form than you wont need to grease them. If you are using metallic or ceramic forms, grease them with a bit of coconut oil to get them out easier once they have been baked. Place in the oven at 180 Celsius or 345 Fahrenheit for 12-15 minutes. Remove and let them cool to room temperature.

This silicone bar mold works great for all sorts of oat bars

Step 3 – Chocolate Layer

Last but not least, lets add the chocolate cover. To melt your chocolate make a Bain Marie. A Bain Marie is basically a hot water bath. Instead of melting the chocolate directly over the heat, we melt it over water steam which has a constant temperature and does not burn the chocolate.

Get a small or medium sized saucepan and add an inch or two of water. Next place a heat proof bowl over the sauce pan. The water should NOT directly touch the glass bowl.

Place the chocolate (keep 20% aside for tempering) in to the glass bowl and stir until its well melted.

Expert tip: If you want to make the chocolate thinner, you can add coconut oil. Adding one or two tablespoons of coconut oil will make the chocolate thinner. Just don’t add too much at a time. Add a bit test and go again.

Once the chocolate has completely melted, take it off the heat and keep stirring. Add in the 20% of chocolate you kept aside and stir until its also melted. This is a trick that will help you to temper the chocolate without much hustle.

Pour the melted and tempered chocolate over the bars and hit them on the bar to let it even and settle. You can now embed some nuts or raisins in to the bars. Let the chocolate set and remove the bars from he mold.

You can use muffin tin if you don’t have bar mold!

Tips & Tricks

  • You can mix it up by adding raisins, nuts or other fruits to the bars or the chocolate
  • Temper the chocolate by adding cooling it slowly. An easy way to do this, is adding chocolate after it has melted and stirring it in until it dissolves.
