Bite into these thick chewy Chocolate Oat Bars for an insanely delicious treat. The chocolate filling is rich and smooth from the melted chocolate chips and sweetened condensed milk. The brown sugar and oats make the crust and crumbly topping thoroughly munchable. Then, top it all off with your favorite nuts, like walnuts, pecans, or peanuts.
I know some of you will agree with me: the best dessert is a big dessert. These Chocolate Oat Bars are so nice and thick, you can clearly see the different layers of crust and chocolate, then the nuts and crumble on top. Hand somebody one of these and they’re going to smile before they even take a bite.
Making Chocolate Oat Bars
Start by having your butter softened and your eggs to room temperature. Then grab your 13 x 9″ baking dish; use your good one for this recipe, because you’re going to love these. Lightly grease the dish and preheat your oven to 350°.
Mix the butter and brown sugar together until nice and creamy. I used light brown sugar, but you can use the dark if you prefer more of the molasses flavor.
Then just add in the rest of the crust ingredients: eggs, vanilla, flour, salt, baking soda, then the quick oats. Once everything’s mixed, reserve about a third of the batter and set aside. You’re going to use that on top after we do a few things first.
Press the other 2/3 of the batter into the dish and pat it flat.
The Chocolate Filling
In a medium sauce pan, melt the chocolate chips with the sweetened condensed milk, butter, vanilla extract, and salt. Stir constantly so it doesn’t scorch on the bottom, then remove as soon as the chocolate has all melted.
Here’s a silly tip: don’t stir melted chocolate with a wooden spoon – they almost never come clean. Use a plastic spatula instead.
Pour the chocolate mixture over the crust in the baking dish.
Sprinkle on your favorite nuts. I used walnuts for this recipe and only roughly chopped them so they would be a little larger and more visible. You can also use pecans or peanuts, whatever you love most (or have on hand).
Rustic Crumbly Topping
The last part before baking is to grab the reserved batter from earlier. Using your hands, break off small chunks and evenly sprinkle over the chocolate and nut layer. Bake for 25 – 30 minutes or until it starts to turn a beautiful golden brown.
Allow them to cool just a bit once they’re done baking, then dive in and enjoy the fruits of your labor.
Super delicious served warm with a scoop of vanilla-bean ice cream. Oh my!
