*If you’d like to easily remove the bars from the baking pan to cut clean squares, first line the 8x8 pan with a piece parchment paper large enough to cover the bottom and hang over the sides of the pan about 1 inch. Then press the dough onto the parchment paper and bake as described. I like to remove the bars from the pan before I add the peanut butter and ganache toppings. This allows me to get the toppings all the way to the edges and cut the bars evenly.
**You can also make ganache in the microwave. Simply warm the heavy whipping cream in a microwave safe bowl, 20 seconds at a time, stirring between each interval, until the cream is hot but not boiling. Then add the chocolate chips and cover with a plate. Continue as described above.
***This amount of chocolate chips and cream makes a thick layer of ganache for the tops of the bars. If you’d like a thinner layer, simply use 1/4 cup heavy cream and 1 cup of chocolate chips.
