Ingredients

18.3- ounce Brownie mix and ingredients called for on the back

Peanut Butter Layer:

½ cup salted butter melted
2 ½ cups powdered sugar
1 ½ cups creamy peanut butter
½ teaspoon vanilla extract
Pinch of salt

Ganache Layer:

2 cups semi-sweet chocolate chips
2 Tablespoons salted butter
1 cup heavy cream

Instructions

Prepare a 9x13-inch baking pan by spraying it with non-stick cooking spray and lining it with parchment paper, set aside.
Preheat the oven to the temperature recommended on the box mix.
Prepare the brownie mix according to the directions on the package.
Bake the brownies for the recommended time on package, remove from the oven and allow them to cool.
While the brownies are cooling, prepare your peanut butter layer. In a medium sized bowl add the butter, powdered sugar, peanut butter, vanilla extract and salt.
With a hand mixer, beat this together until smooth. This will be on the thicker side, set aside.
To make the ganache. Add chocolate into a medium sized glass bowl (you will need a lid or plate that will cover this) and set this aside.
In a small saucepan, melt the butter over medium heat, once melted stir in the heavy cream. Whisk this mixture constantly while increasing the heat to medium high. Heat until it just starts forming bubbles.
Immediately, pour the butter and heavy cream mixture over the bowl of chocolate and cover it with the lid. Let sit for 5 minutes.
After 5 minutes, remove the cover and stir combing the chocolate and cream together until you get a smooth melted consistency.
As the ganache cools, it will thicken slightly which is fine, just stir ganache when you are ready to spread it.
Once the brownies have cooled, with a spoon dollop of the peanut butter mixture over the brownies.
Using an offset spatula, smooth the mixture out to cover the brownie layer completely.
Pour the ganache on top and again with an offset spatula smooth out covering the peanut butter layer.
Place the brownies into the refrigerator and allow them to cool and set for at least 30 minutes for easier cutting.

Notes

Use your favorite brownie mix for this recipe or your own homemade. See some ideas above.
In place of creamy peanut butter, you can use chunky for a texture contrast.
These are best refrigerated for at least 30 minutes before cutting and serving.
You want to make sure that you cool your brownies before adding the peanut butter layer so it does not melt.
Switch up the chocolate in the ganache recipe, see some ideas above.
These can be frozen, see above on how to do that.
Sprinkle these with some powdered sugar for some extra sweetness.
