Let’s Get Started!

The ingredients for these bars are those that you likely have on hand in your pantry.  This makes them easy to prepare on a spur of the moment.

Heating the butter and brown sugar

Even though we won’t be baking these bars, the butter and sugar will still need to be heated on the stove so that the oats have something to stick to.cooking butter and brown sugar

Adding the oats

Once the mixture is nice and creamy and well combined, stir in the oats and sea salt.  You’ll stir this mixture for about 5 minutes so that it is well combined.buttery oats

Time to layer the peanut butter oatmeal bars

You’ll use about half of this mixture for the bottom layer. Spread it out evenly and press it down into the prepared pan so that you’ll have a nice firm base for the peanut butter chocolate layer to come.Oats and butter in a pan

Peanut butter chocolate time!

Combining the stars of this recipe could not be easier. Just heat the chocolate chips and peanut butter in a microwave safe bowl. I like to do this in 30 second increments, stirring well between each, until you get a nice creamy mixture.Melted chocolate

Let’s add the Reese’s layer!

This thick chocolatey layer gets poured over the buttery rolled oats giving them the second layer which is sort of like a Reese’s Peanut butter cup.melted chocolate on oats

Add the rest of the oats and drizzle the whole thing with some more melted chocolate.  YUM!!oat bars with chocolate drizzle

Time to get cold…

All that is left is to place the pan of chocolate peanut butter oatmeal bars in the fridge to set.  It will probably take about 4 hours to really firm up. This is an important step.

If you try to cut them too soon, they will taste great but be too soft to eat as a bar.  And placing the pan in the fridge is as Easy Peasy as it gets. Now it’s time to relax!Chocolate peanut butter bars

Cutting the bars

It might be tempting to cut into the bars as soon as you take them out of the fridge.  (they look so tempting, right?)  But let them come back to room temperature first.

Doing this will make sure that you get straight even lines and ease of cutting the bars.  Cutting hard chocolate right out of the fridge is not easy. We want pretty bars, not chocolate bark!

Substitutions to make a oatmeal peanut butter bar fit your diet

These amazing bars are gluten-free already but you can easily turn them into vegan or refined-sugar treats, too. If you are looking for a way to make these fit into a special diet that you follow, these substitutes will help you to customize your recipe.

Butter

Earth Balance Spread makes a great vegan substitute for butter in this recipe.  Enjoy Life Chocolate Chips are vegan, too.

Brown Sugar

If you don’t eat refined sugar, you can use coconut sugar in place of the brown sugar. Maple Sugar will also work well.

Peanut Butter

Can’t eat peanuts?  Substitute the crunchy peanut butter with any nut butter.  The bars are already crunchy so you won’t miss the extra texture.

I especially like making them with Sunflower seed butter, since it has a very similar taste and you won’t be baking the bars, so you don’t need to worry about it turning green.

DRIZZLE:

Instructions

  3. Stir in the old fashioned oats and sea salt. Cook, stirring constantly, for about 4 to 5 minutes.

Notes

A note on cutting the bars. I like nice sharp edges to my bar recipes but when you have hardened chocolate in the middle AND on top, cutting them when cold is a challenge.

The answer is to bring the bars to room temperature before slicing them. You'll get nice clean edges with no broken chocolate bits.
