Symphony Brownies

"Turn a box of brownie mix into a rich, delicious, show-stopping dessert in just minutes. These Symphony Brownies are embarrassingly easy, but taste exquisite. I’ve had people tell me they are the best brownies they’ve ever tried!"

If you are looking for a brownie that will stop everyone in their tracks, give this recipe for symphony bar brownies a try. Who can resist brownies with a candy bar center, especially when the candy bar is loaded with toffee and almonds?

These are so addicting. First time I made these several people that tried them wanted to pay me to make them a batch. I will be making these a lot.

Symphony Brownies

Servings – 12/24 - These are rich smaller cuts will go along way Prep Time – 10 Minutes Cook Time – 30 Minutes Ingredients:

  • 1 21.5oz Duncan Hines brownie mix, any mix 20+ ounces or more will work

  • 1/3 cup vegetable oil

  • 1/4 cup water

  • 2 eggs

  • 3 - 6oz Hershey Symphony chocolate bars, almonds and toffee is my favorite


Preheat oven to 350 degrees (or according to the directions on your brownie mix). Spray a 9x13" baking pan with non-stick spray. I like to line it with foil first. Set aside.

Mix the brownies according to directions on the box.

Spread half of the batter into prepared pan. It will be a thin layer.

Place the 3 candy bars side by side on top of the batter. You don’t need to break or chop up the candy bars, you can just leave them whole.

Carefully spread the remainder of the brownie batter over the top of the candy bars.

Bake for 26-32 minutes, or according to package directions.

Let cool before cutting. (If you can wait!)


Brownie variations:

I think the symphony bars with toffee and almonds are best, but you can certainly use just the plain milk chocolate bars instead. Or of course you can substitute another brand you favor.

If you would like a thicker and higher ratio of brownie to candy bar, you can use two brownie mixes. 

For extra crunch, you can toss some chopped nuts into the brownie batter.

For extra thick brownies, you can bake in a square 8 or 9 inch pan. You will only need two of the candy bars.

Follow ther directions and added ingredients to the box of brownie mix you purchase.

Storing leftovers:

These symphony chocolate bar brownies will keep at room temperature for 4-5 days if covered tightly or placed in an airtight container. I don’t recommend storing them in the refrigerator, the candy bar gets too hard.

"Two layers of fudgy brownie with a candy bar in the middle – these brownies are a chocolate lover’s dream! I found a similar recipe years ago and played with different bars of chocolate. I am a huge fan of the toffee Symphony candy bars, so I knew I had to give the recipe a try."
