• Preheat oven to 350°F. Line a 9x13 baking dish with parchment paper, set aside.

Prepare the brownie

• Place butter in a large microwave safe mixing bowl, melt completely. Add sugar, cocoa, vanilla and eggs. Whisk to combine well. Add remaining ingredients. Whisk until completely combined, but do not over mix.
• Pour into prepared baking dish. Sprinkle about 24 mini Snickers over batter, press into batter with a spatula. Bake for 20-25 minutes or until a tooth pick comes out clean. Place in the freezer to cool, about 15 minutes.

Prepare the caramel sauce

• Meanwhile combine caramels and heavy cream in a microwave safe bowl and heat (30 seconds at a time) until melted. Stir to combine.
• Reserve 1/2 cup peanuts, sprinkle remaining peanuts over cooled brownie and pour caramel sauce over top, reserving about 2 tablespoons for garnish (if desired). Place in freezer to cool.

Prepare nougat frosting

• Meanwhile, combine cream cheese, marshmallow and peanut butter in the bowl of a stand mixer (or in a large bowl with an electric mixer) fitted with a whisk attachment. Beat on medium speed until light and fluffy, about 3-5 minutes. Spread frosting over top of cooled brownie.

Decorate the brownie

• Sprinkle remaining Snickers bites over the top of the frosting. Drizzle melted chocolate. Sprinkle with reserved peanuts. Drizzle with reserved caramel. Place in freezer for 20 minutes to set frosting and drizzle or serve immediately.
