When you take a pan of fudgy brownies and fill them with  milk chocolate toffee bars, the result is a batch of Symphony Toffee Brownies, one of the tastiest treats you’ll ever taste!!

I was heading to Colorado with 5 girlfriends and got an email asking whether I was bringing any baked goods. These brownies with toffee were already in the oven! We did a good job devouring the batch. Not a crumb came home.

Symphony Toffee Brownies

Are you familiar with Symphony Bars? They are a Hershey product with the milk chocolate ingredients tweaked for a creamier texture. With both a plain and almond toffee version, the latter was used in these rich, fudgy Symphony toffee brownies!

This recipe comes from my friend, Diane Morrissey. She’s an extraordinary cook; check her out on Instagram. When I made these first in 2011, I had just purchased Bake! by Nick Malgieri, the baking guru.  When trying to decide which brownie recipe to use for these Toffee Brownies, I went to Nick’s book and quickly decided on his Florida Brownies which are his take on Maida Heatter’s Palm Beach Brownies.  They did not disappoint. If they aren’t rich enough for you, try adding a layer of chocolate bars in the middle. They’re definitely sublime.

But Diane’s version is even easier! She uses a box of Ghirardelli’s brownie mix which make these rich uber chocolaty brownies a  breeze to prepare!

Tips for Making These Easy Brownies with Toffee

If you’re not much of a baker or short on time, just grab a box of brownie mix and your friends will think you’re a genius. These brownies with toffee have a delicious, rich, crunchy surprise in every bite!

The eggs, sugar and vanilla are mixed for up to 10 minutes, so using a stand mixer is the best option if available. Make sure to scrape the bowl a couple times during the process to make certain all the batter is beaten to the same consistency.

Since the chocolate bar in the center will be gooey when the brownies are done cooking, you cannot use the usual toothpick test to check whether your brownies are done. The 35 minute timing worked well for me in two different ovens.

Like with many fabulous brownie recipes, there it a very thin, crisp layer that shatters a bit when you cut these. Using a serrated knife to score them first will help a bit, but there’s really no way to get a perfect, clean cut with every slice.

PRO-Tip: Line your  baking pans with non-stick foil. This ensures the brownies will not stick to the sides of the pan and also helps for easy removal for cutting after they’ve cooled.

Fudgy brownies with a milk chocolate toffee candy bar filling!

  • Author: Liz Berg
  • Prep Time: 30 minute
  • Cook Time: 35 minutes
  • Total Time: 1 hour 5 minutes
  • Yield: 48 brownies 1x
  • Category: Dessert
  • Method: Mixing, Baking
  • Cuisine: American



8 ounces (2 sticks) butter
8 ounces unsweetened chocolate, chopped
5 eggs, at room temperature
1 tablespoon vanilla
3 3/4 cups sugar
1 2/3 cups flour


4 6.8 ounce Symphony milk chocolate bars with almonds and toffee chips


Line 9 x 13 pan with aluminum foil.  Grease foil with cooking spray.

Prepare brownies as recipe or box states.

For these homemade brownies, preheat oven to 375º.  Line 9 x 13 inch pan with non-stick foil or use regular foil and spray with cooking spray. Set aside.

Melt butter and chocolate together in microwave, using 30 second increments, stirring frequently as to not over heat chocolate until melted and smooth.  Set aside.

Combine eggs, vanilla and sugar in large bowl (add a large pinch of salt if using unsalted butter).  Using mixer, beat on high, scraping a few times, till very light and fluffy, for up to 10 minutes.

Add chocolate and mix in on low, scraping sides of bowl occasionally.  Sift flour into bowl and mix till just combined.

Spoon half of batter into prepared pan.  Smooth  the batter to cover bottom of pan.  Place the candy bars side by side over batter, cutting the 4th bar into sections to finish covering the batter.  Top with the rest of the brownie batter and smooth the top.

Bake for 35 minutes (if using a box mix, follow baking temperature and time on the package).  Cool completely, then remove from pan using foil to lift.  Cut and serve.


*Or use 2 box mixes for a 9 x 13 pan like Ghirardelli brand.  You may need to add some additional baking time to the time listed on the box.
