Oatmeal Brownie Milky Way Bars are dessert bars with a layer of oatmeal brownies on the bottom, a Milky Way candy bar and caramel filling, and another layer of oatmeal brownies on top. Try my Oatmeal Chocolate Chip Bars for another ooey-gooey dessert bar.

Oatmeal Brownie Milky Way Bars

I love oatmeal bars. I love brownies. Oh, and I love Milky Way candy bars, too! So, it only makes sense to combine three of my favorite things to make one very likeable, and yummy, dessert bar!

Bar Ingredients

There are two parts to this recipe–the chocolate caramel filling and the oatmeal brownie layer.

Candy Bars: I chose original Milky Way candy bars to melt with the caramel for some added chocolate to the filling.

Caramel: The easiest caramels to use in the filling is caramel bits. They are ready to go with no unwrapping of plastic necessary.

Oatmeal: I used Old-Fashioned oats in my recipe but you can certainly use quick oats. We love oatmeal so love the consistency, texture, and flavor that an old-fashioned rolled oat adds.

Milky Way Filling

To make the ooey-gooey chocolate and caramel filling for these bars, get out a medium saucepan. Add the candy bars, caramels, and heavy cream to the saucepan. Simmer over medium to medium-low heat until fully melted. Remove the saucepan from the heat and let the mixture cool for about ten minutes. 

Oatmeal Brownie Mixture

To make the oatmeal brownie crumble, first, in a large bowl, combine the oats, flour, baking soda, salt, brown sugar, and butter. Use or fork or your hands (I prefer just using my hands) to combine the ingredients. It is okay if the butter isn’t completely broken down, but keep the pieces to the size of a pea. Next, add in the brownie mix, egg, and oil. Stir until just combined.

Assembling Oatmeal Brownie Milky Way Bars

Once the Milky Way and caramel filling has cooled and the oatmeal brownie crumble is mixed, it’s time to get the layers in the pan and the bars baked! First, be sure to line the pan with parchment paper or use nonstick cooking spray. Next, evenly spread half of the oatmeal brownie mixture into the prepared baking dish. Press it firmly to flatten.

After the bottom layer is pressed in the pan, pour the cooled Milky Way mixture on top. Make sure the filling gets all the way out to the corners and covers the bottom layer. Finally, place the remaining oatmeal mixture on top.

The easiest way to do this is to grab a small amount of the mixture, flatten it a bit in your hands, and place it on top of the filling. Continue to do this with the rest of the crumble, like putting together pieces of a puzzle. It is okay if some of the filling is showing. Bake the bars for 25-30 minutes. Remove from the oven and set pan on a cooling rack to cool before cutting and serving.  Add a dollop of vanilla ice cream on top and enjoy!

    1. Hi, Pat! I work with iambaker and am happy to help with questions. Brownie mix is the dry ingredients that are mixed with wet ingredients to make brownies. You can buy it in a box or make your own homemade brownie mix. I hope this helps, and have a great day!

  3. If you use your homemade brownie mix, how do you calculate the 2 cups of mix? Is it 1 batch of the brownie mix without the wet ingredients from that mix? Or the whole brownie mix you have linked plus the additional wet ingredients?
    Thank you!

    1. Hi, Susan! I work with iambaker and am happy to help with questions. To use the homemade brownie mix, it is two cups of the dry mix ingredients. Then, just follow the rest of the oatmeal brownie milky way bars recipe. I hope this helps, and have a great day!

  4. These look amazing! Due to allergies, could I swap out the candy bars and pieces for allergy friendly caramels and a little chocolate with the cream please?

    Thank you for amazing treats!
