    Chocolate Truffle Fudge Bars

    Chocolate Truffle Fudge Bars are melt-in-your-mouth delicious. These triple chocolate bars have a brownie base, a chocolate truffle layer and smooth chocolate frosting on top.

    Chocolate Truffle Bars Slices

    A couple of weeks ago, I made some bars that were going to be served after church on Sunday. I didn’t know what to make, but as a food blogger, it shouldn’t be too difficult, right? Ha! I am not as well stocked as I should be. I looked in my pantry and found a cake mix. On the back was a recipe for Rocky Road Bars and I thought, perfect, I will make these. Then, I realized that I didn’t have enough marshmallows.

    So, it was on to plan B, which was bars that are basically three layers of chocolate. I made the bars, wrapped the pan in foil and stuck them in my fridge with the hope that they would suffice. I didn’t make it to church that Sunday because I was home with Zack, who had bronchitis. Brian brought the bars for me and I put them out of my mind. Well…it ended up that they were a huge hit! Everyone was raving about them, asking me what they were and if they could have the recipe.

    Here’s the thing, I didn’t have a recipe. It was one of those things that was thrown together, last minute. So, I made them again and this time, I wrote down the recipe. Here is the much anticipated, very delicious, Chocolate Truffle Bars.

    Chocolate Buttercream Truffle Layer

    Start by making a thin pan of brownies in a 9×13″ pan. Use whatever recipe you want or make them from a box. Most boxes of brownies are meant to be made in an 8×8″ pan and I made mine in a 9×13″ pan instead so therefore they are thin. I like my brownies to be on the fudgy side, so I undercook them by a couple of minutes.

    Next, mix up some rich, chocolate buttercream frosting to be used as the truffle layer. Spread the chocolate buttercream truffle layer over the brownies once they have cooled. I plopped little piles of buttercream all over the brownies and used an offset spatula to carefully smooth it out.

    Chocolate Frosting Drizzle

    Mix together the chocolate frosting and spread over the truffle layer. I think I stirred mine a little too vigorously because as you can see in this picture, there are small air bubbles in the chocolate. Try to slowly stir the boiling cream and butter mixture into the melted chocolate chips until the mixture is smooth.

    Fudge Slices

    Allow the bars to cool and firm up before cutting. I covered mine and placed the pan in the fridge. To cut the bars, run a knife under hot water, quickly dry it off and use the hot (dry) knife to cut through the bars. It will go through as smoothly as if cutting through butter. I continued rinsing/heating the knife before each cut.

    I’m not sure if you can tell from the photo, but my brownies were a little too fudgy so they tended to stick to the bottom of the pan. Delicious, but hard to remove. Next time, I will cook them a tiny bit longer.

    Chocolate Fudge Bars

    Go ahead and take a bite! These rich, creamy Chocolate Truffle Fudge Bars are so worth it!

    Ingredients

    • 16.3 oz brownie mix
    • 2 tablespoon water
    • ½ cup vegetable oil
    • 2 large eggs

    Chocolate Truffle Layer

    • 8 ounces unsweetened bakers chocolate
    • 1 cup butter, softened
    • 2 teaspoons vanilla extract
    • 6 cups powdered sugar
    • 4-5 tablespoon heavy cream
    • 2 tablespoon strong coffee cooled
    • ¼ teaspoon salt

    Chocolate Frosting

    • 2 cups semi-sweet chocolate chips
    • ½ cup heavy cream
    • ½ cup butter

    Instructions

    • Prepare the brownies in a 9x13-inch pan according to the instructions on the box. Allow them to cool after baking.

    Chocolate Buttercream Truffle Layer

    • Melt unsweetened chocolate according to the instructions on the package. Allow chocolate to cool to room temperature.
    • Brew a small amount of strong coffee and place in the fridge to cool.
    • Beat butter and vanilla until light and fluffy.
    • Add powdered sugar slowly, 1 cup at a time, beating between each cup. (I put my splash guard on my Kitchen Aid mix and left it on low while slowly pouring in the powdered sugar. Then, turned it on high to beat it in, and then repeated the process.)
    • After the last cup of powdered sugar has been added, scrape down the sides of the bowl and beat for 1 minute.
    • Add the salt, coffee and heavy cream and beat for 1 minute.
    • With the mixer on the lowest speed, slowly pour in the room temperature unsweetened chocolate.
    • Beat for 1 minute on high.
    • Add more heavy cream, 1 tablespoon at a time, if needed.
    • Carefully spread over brownies in 9x13-inch pan.

    Chocolate Frosting

    • Bring heavy cream and butter to a boil.
    • Pour over chocolate chips.
    • Let it sit for a couple of minutes to allow the chocolate chips to melt.
    • Stir gently until smooth.
    • Pour over chocolate buttercream truffle layer in 9x13" pan and gently spread until evenly coated.
    • Allow the bars to cool and set before cutting into small pieces.

        Yup, it’s three layers: brownies, Chocolate Buttercream Truffle Layer and Chocolate Frosting (which is basically ganache). Happy baking!

      I’m confused. These look fabulous, but when I read the recipe, it says to start with a pan of brownies. When I look at the pics, the bottom layer looks very flat – like a crumb crust. If I make a pan of brownies and then add the other 2 layers of mixtures over the brownies, I don’t see how the pan can hold all of it. I’m sure I’m just missing something (probably something very obvious!), but can you please help me with that? I would love to make these. Thanks so much! Blessings!

        Yes, my brownie layer is thin and fudgy. Most brownie mixes are meant to be made in an 8×8 in pan and I made mine in a 9×13 inch pan. I will add that to the instructions, just in case others are confused. Happy Baking!

          Thanks so much! I was thinking I needed to use a recipe for a 9X13 pan if I used that size. Can’t wait to make these
