Equipment

Ingredients

10 tablespoons unsalted butter
7 ounces semisweet chocolate or bittersweet chocoalte, chopped
1 teaspoon vanilla extract
3 large eggs room temperature
1 cup granulated sugar
1/2 cup brown sugar light or dark, packed
1 cup flour
1/4 cup cocoa powder Dutch process or unsweetened, sifted
1/2 teaspoon salt

Toppings

peanut butter cups use regular or the special Reese's peanut butter pumpkins
Mini Reese's Pieces optional, regular Reese's Pieces or regular or Mini M&Ms can also be used

Instructions

Line and lightly butter an 8 x 8 inch pan with parchment paper leaving enough to hang from the sides. Preheat oven to 350 degrees F.
Place chopped chocolate and butter in a large heatproof bowl set over a saucepan of simmering water. Stir the mixture as it melts. Remove bowl from heat and whisk the sugar in.
Add the eggs, whisking after each egg. Whisk in the cocoa and salt, then fold in the flour until just combined. Avoid overmixing.
Pour the brownie batter into the pan and use a spatula or offset spatula to evenly spread out the brownies and smooth out the top. Bake 30-35 minutes until a toothpick when inserted in the center comes out clean and with only a few crumbs. Keep in mind the brownies will continue to cook slightly when out of the oven, so do not over bake them. Place pan on a wire rack and allow brownies to cool slightly.
Five minutes after taking the brownies out of the oven, gently press the peanut butter cups on top of the brownies in any arrangement you like! Use Reese's Pieces or M&Ms to create monster faces, if desired.

Notes

Slicing brownies: Allow brownies to cool completely before slicing. Use a long, sharp knife to cut brownies. For best results run the knife under hot water and wipe the knife clean after each cut.

Storage: Store leftover brownies for 3 to 4 days at room temperature or for up to 5 days in the fridge. Freeze brownies for up to 1 month. Defrost on the counter.
