Make the Cake
Preheat the oven to 350F degrees. Spray a 10x15 inch jelly roll pan with non-stick cooking spray and dust with flour. Set aside
In a large bowl whisk together the flour, cocoa, baking powder, baking soda and salt. Set aside. In a separate large bowl using a stand or electric mixer on medium speed, beat together the oil and sugars followed by the eggs and vanilla. Turn the mixer down to low speed and carefully beat in the buttermilk followed by the flour mixture. Turn off the mixer and scrape down the sides of the bowl as necessary. Once evenly combined, carefully beat in the hot coffee. The mixture will be very thin.
Pour the cake batter into the prepared pan and bake for 20-25 minutes or until an inserted toothpick comes out clean and if you give the pan a gently nudge the middle doesn't wobble. Remove from the oven and allow to cool.
Make the Salted Caramel (Skip this step if using prepared caramel sauce)
Add the sugar to a medium saucepan over medium heat. Stir gently with a rubber spatula or wooden spoon. The sugar will first form clumps, then it will turn amber in color and the clumps with dissolve until you have a smooth mixture.
Then add in the butter while gently stirring. The mixture will bubble and boil. Once the butter is combined (about 2 minutes), carefully pour in the cream while gently stirring. The mixture will boil quite aggressively here. After the cream is combined, remove the pan from the heat and whisk in the vanilla and salt. Allow to cool fully before using
Make the Caramel Frosting & Serve
In a large bowl using an electric mixer on medium speed, beat the butter until fluffy. Then turn down the mixer to low speed and carefully beat in 2 and ½ cups (or about half) of the powdered sugar, then once combined turn the mixer to high speed and beat for an additional 10 seconds. Turn off the mixer, add in ½ cup of salted caramel and the vanilla and salt. Beat on low speed until combined. Beat in 2 more cups of the powdered sugar on low speed, then turn the mixer up to medium speed for 10 seconds. Add in the whipping cream 1 tablespoon at a time, until the desired consistency is reached. Beat in a bit more powdered sugar as needed.
Frost the cake using a flat knife. If the frosting brings up cake crumbs, first frost a thin layer, then refrigerate the cake for 30 minutes and frost again with the rest of the caramel frosting.
To serve, cut into pieces and drizzle each with salted caramel and decorate with a few Rolo candies
