Heath Bar Fudge Brownies – What more needs to be said?  Decadent?  Yes.  Rich?  Yes. Unbelievably gooey?  Yes.

If you are chocolate lover as well as a toffee lover, look no further. We’ve got the brownie for you. We love our Ultimate Chocolate Brownies and our Chocolate Cheesecake Brownies so much, too. But, there is something pretty intensely good about these, too. They go fast, so be prepared for that! And have plenty of napkins on hand!

Heath Bar Fudge Brownies are not difficult and can actually be made in stages.

For the brownies, you’ll want to melt the chocolate in a double boiler. If you don’t have a double boiler, no worries. Just bring a large pot of water to a simmer, and then place another metal bowl over the steaming water. The chocolate will melt quickly.

We told you these are off the hook when it comes to amazing chocolate taste! And of course, melted butter just make it even more better…and decadent!

Next, it’s time to mix the chocolate into the batter. Sometimes it can be confusing when you’re standing in the baking section of the supermarket, and there are various types of chocolate. For this recipe, we go with unsweetened chocolate.

Folks, we’re building the best brownie on the block, we promise!

Oh, just look at that!

We use a lightly greased 9×13-inch dish for baking the brownies.

The smell is the stuff of incredible chocolate dreams.

EXPERT TIP: The brownies can be baked and covered with foil for up 2 days before icing and serving.

The icing comes together quickly.

Be sure to let the brownies cool completely before icing them.

Just amazing.

Why not a little fudge icing?!

A healthy sprinkling of toffee bits on top is all that’s left.

That, and digging in. Be sure to have a nice tall glass of cold milk nearby.

These are so good and always very well received when we serve them!
