One of the most popular desserts in our household.

We LOVE a good oatmeal cookie and the chocolate ganache on top takes it to another level.

The oatmeal cookie base is soft and chewy with crisp edges. It pairs perfectly with the rich, smooth chocolate ganache layer on top.

It is all brought together with sea salt flakes on top to balance out the sweetness.

However, a big highlight for this recipe is how simple and easy it is to make!

Why You Will LOVE This Recipe

Flavor. I could eat the chocolate ganache on its own because it is THAT good.

However, it is the perfect topping to the buttery oatmeal cookie.

Each bite keeps you coming back for more!

Texture. The cookie edges have the slightest crunch with a soft and chewy center.

Topped with a creamy chocolate ganache and sea salt flakes are what bring it all together. It is the perfect balance of richness with the addition of salt.

Simple. This recipe couldn’t be any easier!

The oatmeal cookie batter comes together quickly and the chocolate ganache is even simpler to make.

Frequently Asked Questions

Is this recipe gluten-free friendly?

If you use Gluten Free All Purpose Flour and Gluten Free Rolled Oats, then this recipe is gluten-free friendly!

Can I use any type of chocolate of the ganache?

I suggest using a semi-sweet or dark chocolate so that it isn’t too sweet when paired with the oatmeal cookie base.

Do I have to wait for the oatmeal cookie base to cool before adding the ganache?

You should wait until the oatmeal cookie base is about fully cooled before pouring over the ganache.

How do I know the chocolate ganache is fully set?

The chocolate should have a shiny, glossy finish. It should take about 45-60 minutes to set in the fridge or about 2-3 hours at room temperature.

What is the best way to store the Oat Fudge Bars?

Store in an airtight container at room temperature for up to 5 days or in the fridge for 1 week.
