Step 1

Preheat oven to 350°F. Line a 9×13” pan with foil and spray with cooking spray.

Step 2

Place butter and 63 Hershey’s Kisses in a large, microwave safe bowl. Heat for about 2 minutes, stirring every 30 seconds, until the Kisses are melted. Mixture will appear separated.

Step 3

Stir in sugar. The mixture will appear to be seized, but mix in the vanilla and eggs and it will smooth out. Stir in salt and flour.

Step 4

Pour into prepared pan. Bake about 20-22 minutes until the top is slightly cracked and a toothpick comes out almost clean. Cool completely before frosting.

Step 5

To make the frosting: heat the heavy whipping cream for 30 seconds. Pour over unwrapped Kisses in a bowl and let sit for 30 seconds. Whisk until smooth. If needed, heat the mixture an additional 15-20 seconds to aid in melting. Pour over brownies, smooth to a thin layer, and let harden.

Step 6

Slice into bars and store at room temperature for up to 4 days.
