Chocolate Fudge Oatmeal Bars

These Chocolate Fudge Oatmeal Bars have 2 layers of oatmeal with a layer of rich chocolaty fudge in between. They are one of my very favorite bars to bake and to eat.

I must say bars in general are one of my favorite desserts to make. They’re so easy and versatile. When it comes to a sweet treat, I’ll almost always choose a bar or brownie over a cookie

Sorry cookie lovers!


There’s just enough chocolate in these Chocolate Fudge Oatmeal Bars to satisfy a chocolate craving, but the oatmeal layers add a nice flavor and texture contrast. Some instant coffee granules added to the fudge layer add to the flavor but don’t really add a “coffee” taste.

The same oatmeal mixture of oats, flour, brown sugar, and butter is used for the bottom layer and the top, but the texture of the bottom is more crunchy and the top is more crumbly.


Together all the layers combine to make one delicious moist and chewy bar. You are going to love these Chocolate Fudge Oatmeal Bars. They are the perfect after school snack or picnic treat. Grab a glass of milk and enjoy a few!

  1. I will use the crust recipe as another option for cream pies – very good!

    The filling is definitely like a fudge vs. a bar cookie or a brownie.
    Fudge lovers should really enjoy it.

    Thank you!

  2. These look so delicious, and I would choose a brownie over a cookie any day, too! Pinning these…they’d be a complete hit!
