5th Step

Melt half a cup of butter in a saucepan over medium heat. Stir in the cocoa powder and milk. Bring to a simmer before removing from the fire.
Whisk the powdered sugar and vanilla extract into the butter until the icing is smooth. Stir in the pecan pieces.

6th Step

While the cake is still warm, use the base of a wooden spatula to create cavities in it. Pour the warm caramel sauce evenly over the cake, followed by the pecan-chocolate frosting.

7th Step

Allow the cake to chill entirely before placing it in the refrigerator for a few hours to allow the flavors to combine. Cut into squares, serve, and relish the delectableness!
