Nutella Truffle Stuffed Brownies

Three Nutella brownies stacked on top of each other.

Nutella Truffle Stuffed Brownies are the ultimate rich, fudgy brownie. Use a boxed brownie mix to make the whole process super simple!

My boys love their Nutella. Generally it’s with a spoon right out of the jar, but I try my best to find creative ways to limit that! I’ve made Nutella Hot Fudge Sauce, I’ve wrapped it in phyllo dough and baked crispy cigars, I’ve even made whole layer cakes with Nutella. (Click HERE for all my Nutella recipes).

Today, though I’m going back to basics(ish) by baking Nutella right into a brownie. Actually I’ve created a Nutella Truffle mixture and layered that inside a brownie. So you’re basically eating a brownie and a truffle all at once. Yes.

The truffle layer stays pretty intact during the baking process, so you get a true thick layer of Nutella right in the center.

You can absolutely use a scratch brownie recipe in this recipe, if you prefer. I just used a boxed brownie mix, because I had one in my pantry and thought it would simply the whole process. I did, however, add some chocolate chunks to my brownie batter to amp it WAY up.

A pink spoon is used to stir brownie batter in a mixing bowl.

The filling is just Nutella, powdered sugar and a little milk. It will be VERY thick.

To assemble the brownies just spread half of the batter into a prepared pan.

Using your hands portion out some of the nutella filling and flatten it. Layer this on top of the batter. It can (and will) overlap, which is 100% alright alright alright.

Bake the brownies up and they will be tré gorgeous.

Allow them to cool completely before cutting. Or not. Whatever.

I made these last night and doubled the recipe and made them in a 9×13 pan. They are delicious! It’s like frosted brownies but with frosting in the middle. I didn’t use all of the doubled Nutella truffle mixture so I’ll have to find another recipe to use it in or eat it : ) I used 2 boxes of Ghiradelli Dark Chocolate Premium Brownie mix and it had chocolate chips already. It had great dark chocolate flavor and not too sweet. Next time I would add more of the truffle mixture but this is my new go-to brownie recipe.… Read more »
