Ingredients

1 box Betty Crocker Fudge Brownie Mix

This is the base of the recipe. The brownie mix creates a rich, chocolatey batter with a fudgy texture. Using a boxed mix keeps the recipe quick and reliable, making it perfect for busy home cooks.

Eggs, oil, water per package

These ingredients are used to prepare the Betty Crocker Fudge Brownie Mix according to the package instructions. The eggs help bind the batter, the oil adds moisture and richness, and the water helps bring everything together into a thick brownie batter. Follow the amounts listed on your brownie mix box.

3 giant (4.25 oz) Hershey’s Symphony Milk Chocolate Bars (with almonds and toffee)

These chocolate bars are the special ingredient that makes the brownies stand out. They are layered between two portions of brownie batter, creating a melted chocolate center. The milk chocolate adds sweetness and creaminess, while the almonds and toffee add crunch and flavor.

Step-by-Step Instructions

Step 1: Preheat the oven

Preheat your oven to 350°F. This gives the oven time to heat evenly before the brownies go in. A properly preheated oven helps the brownies bake at the right pace, giving them a fudgy center and set edges.

Grease a 9×13 baking dish well. You can use nonstick cooking spray, butter, or a light coating of oil. Make sure to grease the corners and sides so the brownies are easier to remove after baking.

Step 2: Prepare the brownie batter

In a large mixing bowl, prepare the 1 box Betty Crocker Fudge Brownie Mix according to the package instructions. Add the eggs, oil, and water as directed on the box.

Stir the mixture until a thick batter forms. Be careful not to overmix. You want everything combined, but mixing too much can sometimes make brownies less tender. The batter should look smooth, glossy, and thick.

Step 3: Add the first layer of batter

Pour half of the brownie batter into the greased 9×13 baking dish. Use a spatula or the back of a spoon to spread it evenly across the bottom of the dish.

Try to make this layer as even as possible so the chocolate bars sit flat in the center. It does not have to be perfect, but an even base helps every brownie square get a good amount of chocolate filling.

Step 4: Layer the Symphony bars

Unwrap the 3 giant (4.25 oz) Hershey’s Symphony Milk Chocolate Bars (with almonds and toffee).

Lay the chocolate bars flat across the brownie batter, completely covering the surface as much as possible. Depending on the exact size of your baking dish and the shape of the bars, you may need to gently break a bar into pieces to fit the edges. The goal is to create a full layer of chocolate across the middle of the brownies.

This layer will melt as the brownies bake, creating a rich, gooey chocolate center with bits of almond and toffee.

Step 5: Add the remaining brownie batter

Pour the remaining brownie batter over the chocolate bars. Use a spatula to gently spread the batter so it covers the Symphony bars completely.

Take your time with this step. The top layer does not need to be perfectly smooth, but you do want the chocolate bars covered so they bake inside the brownies rather than sitting exposed on top.

Step 6: Bake the brownies

Place the baking dish in the preheated oven and bake at 350°F for 30-35 minutes.

The brownies are done when the top looks set and the edges are baked. Because there is a melted chocolate layer in the middle, a toothpick test may not come out completely clean. That is normal for this recipe. Look for set edges, a slightly firm top, and a rich brownie aroma.

Step 7: Cool before slicing

Let the brownies cool before cutting them into squares. This helps the chocolate center firm up slightly and makes the brownies easier to slice.

For extra gooey brownies, serve them while still slightly warm. For cleaner slices, let them cool completely before cutting.

Tips for Best Results

Use the correct pan size. A 9×13 baking dish is important because it gives the brownies enough room to bake evenly with the chocolate layer inside.

Grease the dish well. These brownies are rich and fudgy, so greasing the pan helps prevent sticking and makes cleanup easier.

Spread the first layer evenly. The bottom layer of batter supports the chocolate bars, so try to make it as level as possible.

Cover the chocolate bars completely with batter. This helps the candy bars melt into the brownies instead of burning or drying out on top.

Do not overbake. Brownies continue to set as they cool. Baking too long can make the edges dry. Start checking around the 30-minute mark.

Let them cool before cutting. The melted chocolate layer will be very soft right out of the oven. Cooling helps the brownies hold their shape.

Use a sharp knife for slicing. For cleaner cuts, wipe the knife between slices, especially if the chocolate center is still warm.

Serving Suggestions

These Symphony Bar Brownies are delicious on their own, but you can also dress them up for a special dessert.

Serve them slightly warm with a scoop of vanilla ice cream for a rich brownie sundae. The warm chocolate center pairs perfectly with cold, creamy ice cream.

You can drizzle the brownies with chocolate syrup or caramel sauce for an extra sweet presentation. A light dusting of powdered sugar also makes them look pretty on a dessert tray.

For parties or potlucks, cut the brownies into small squares so guests can easily grab a piece. Since they are rich, smaller portions work well.

They are also great served with coffee, cold milk, or hot cocoa. For holidays, you can arrange them on a platter with other easy desserts like cookies, bars, or fudge.

Storage and Reheating

Store leftover brownies in an airtight container at room temperature for up to 3 days. Keep them covered so they stay soft and fudgy.

For longer storage, place them in the refrigerator. Refrigerated brownies can last for about 5 days when stored in an airtight container. The chocolate center will firm up when chilled, giving the brownies a denser texture.

To reheat, place one brownie square on a microwave-safe plate and warm it for a few seconds at a time until slightly soft. Be careful not to overheat it, as the chocolate center can become very hot.

You can also enjoy these brownies chilled if you prefer a firmer, candy-bar-like texture. They taste delicious both warm and cold.

Variations and Add-Ins

This recipe is already rich and flavorful, but you can make small changes while keeping the original idea the same.

For extra chocolate flavor, sprinkle a handful of chocolate chips over the top layer of batter before baking.

For a sweeter finish, drizzle caramel sauce over the cooled brownies before serving. Caramel pairs beautifully with the toffee pieces in the Symphony bars.

For a nutty twist, add chopped almonds on top of the batter before baking. This highlights the almond flavor already in the chocolate bars.

For a holiday version, add colorful sprinkles on top before baking or after cooling. This makes the brownies festive for birthdays, Christmas, Valentine’s Day, or school parties.

For a dessert plate, serve each brownie with whipped cream and a drizzle of chocolate syrup. This turns a simple brownie square into a more polished dessert.

Frequently Asked Questions

Can I use a different brownie mix?

Yes, you can use another brownie mix if needed, but this recipe is written specifically with 1 box Betty Crocker Fudge Brownie Mix. For best results and to keep the recipe as intended, use the mix listed in the original ingredients.

Do I need to prepare the brownie mix according to the box?

Yes. Use the eggs, oil, and water per package directions. The exact amounts may depend on the specific box, so follow the instructions on your brownie mix.

Can I use regular Hershey bars instead of Symphony bars?

You can, but the flavor and texture will be different. The Hershey’s Symphony Milk Chocolate Bars with almonds and toffee add creamy chocolate, crunchy almonds, and sweet toffee pieces, which makes these brownies special.

How do I know when the brownies are done?

The brownies should bake for 30-35 minutes at 350°F. The edges should look set, and the top should appear baked. Because of the melted chocolate bars in the center, a toothpick may come out with melted chocolate on it, so do not rely only on a clean toothpick test.

Should I serve these brownies warm or cooled?

Both ways are delicious. Warm brownies will have a softer, gooier chocolate center. Cooled brownies will slice more cleanly and have a firmer texture.

Can I make these brownies ahead of time?

Yes. These brownies are a great make-ahead dessert. Bake them, let them cool completely, then store them in an airtight container. They are perfect for preparing the day before a party or gathering.

Can I freeze Symphony Bar Brownies?

Yes, you can freeze them. Let the brownies cool completely, cut them into squares, and wrap them tightly. Store them in a freezer-safe container. Thaw at room temperature before serving, then warm slightly if desired.
