    Chocolate Ganache Peanut Butter Bars

    For anyone who loves the combination of chocolate and peanut butter, these chocolate ganache peanut butter bars are for you. These are thick chewy peanut butter bars topped with a silky chocolate ganache then served as is or topped with chopped peanuts or sprinkled with sea salt. These bars are irresistible and decadent.

    I have been working on this recipe for years. My first goal was to produce a moist chewy bar loaded with peanut butter flavor. I've tried all natural peanut butter and the type we grew up with (you know what brand I'm talking about). Unfortunately, the all natural peanut butter didn’t produce great results and made the bars mealy. So Skippy it is.

    I also tried grinding roasted peanuts with flour. I figured it would add a nice crunchiness to the bar along with flavor. Instead, I found it was an extra step not worth doing.

    The bits of peanuts were good, but it made you choke because it was harsh against the throat. It wasn't fun asking people to eat your peanut butter bars and have them choke after chewing. So, unless you're prepared to perform the Heimlich maneuver, I suggest you skip this step.

    When they come out of the oven, the top of the bars are even. After cooling, the top will sink a bit and that’s perfect. The higher edges form a reservoir to contain the chocolate ganache we're going to pour on top.

    These need to be refrigerated to allow for the ganache to harden, otherwise you're going to have a mess. You can also freeze these to speed up the process. If you're using a glass baking pan, make sure you don't go straight from the oven to freezer or the pan may burst. Let it cool a bit first.

    The baking pan is lined with parchment with an overhang on each side. This overhang acts like handles, making it easier to lift the chocolate ganache peanut butter bars out of the pan. This makes it easier to slice.

    The bars are thick and chewy with a nice toothsome texture. You can dress them up any way you want.

    These chocolate ganache peanut butter bars are rich and decadent, therefore, you may want to slice on the smaller size. These are a must for anyone obsessed with the taste of peanut butter and chocolate. Make these and you will see what I mean.

    WANT MORE PEANUT BUTTER FLAVOR?

    Instead of using vanilla, you can use peanut butter whiskey. Yes, there is such a thing and it's pretty awesome in this recipe. You can also use bourbon which has been my go-to since vanilla prices went through the roof.

    Equipment Used

    9x9-inch baking pan
    stand mixer
    Spatula
    Cooling Rack
    Mixing Bowl

    Ingredients

    • 1 cup (226 g) unsalted butter room temperature
    • 1 ½ cups (384 g) creamy peanut butter See Notes 1
    • 1 ½ cups (315 g) light brown sugar packed
    • 1 large egg room temperature
    • 1 teaspoon vanilla or bourbon See Notes 2
    • 1 ½ cups (195 g) flour
    • 1 teaspoon fine salt
    • 1 teaspoon baking soda

    Ganache

    • ½ cup (120 ml) heavy cream

    Additional toppings:

    • Maldon sea salt
    • ¼ cup Salted roasted peanuts chopped
    Prevent your screen from going dark

    Instructions

    • Preheat oven to 350℉.
    • Grease a 9x9 inch square pan with butter or use baking spray.
    • Mix together the flour, salt, and baking soda.
    • In a bowl of electric mixer, beat butter, peanut butter, and sugar until smooth, about 3 minutes.  Add in vanilla and egg.  Mix to combine.
    • Add in dry ingredients and mix until combined.
    • Spread evenly into pan and bake for 20 - 25 minutes or until golden and set.
    • Let cool on wire rack. 

    Make Ganache topping:

    • Combine the chocolate chips and heavy cream in a microwave safe bowl and cook in the microwave for 30 seconds. Stir with a fork as it acts as a mini whisk. Continue heating at 15-30 second intervals, stirring until chocolate is smooth and melted.
      Alternatively, place the chocolate chips in a small bowl. Heat the cream in a small saucepan until the edges start to bubble. Pour the hot cream on top of the chocolate chips and stir until melted.
    • Pour ganache evenly over the bars. Spread evenly over the top or tilt pan to let it run to sides and corners. Place the pan in the fridge or freezer until the chocolate is set. Once cooled, cut into squares. You can cut larger bars which will yield you 16 or smaller bars of 24.
    • Top with your choice of toppings or serve plain.

    Notes

    Notes 1: I don't recommend natural peanut butter here.
    Notes 2: If you have peanut butter whiskey, you can use it here. It gives a very nice flavor to these bars. I have a bottle on-hand to use for all my peanut butter recipes.

      The directions call for sugarS but the recipe only lists brown sugar. Is there supposed to be granulated sugar in this recipe?
