For the Brownies

  • 3/4 cup salted butter
  • 12 ounces good quality semi-sweet or dark chocolate chips or bars, chopped
  • 1 cup + 2 TBSP granulated or cane sugar
  • 1/3 cup + 1 TBSP brown sugar
  • 4 eggs
  • 1 and 1/2 tsp vanilla
  • 1 cup all-purpose flour
  • 3 TBSP cocoa powder
  • 1/4 tsp salt

Homemade Hot Fudge Sauce

  • 1 cup good quality dark chocolate chips or bars, chopped
  • 1 cup good quality milk chocolate chips or bars, chopped
  • 1/2 cup granulated sugar
  • 1 can evaporated milk (12 ounces)
  • 1 and 1/2 tsp vanilla
  • 1 TBSP salted butter
  • 1 package samoa cookies Or any kind of cookies you prefer, Oreos could work here

Homemade Caramel Sauce

  • 1 cup granulated sugar
  • 6 TBSP salted butter, cut into chunks
  • 1/2 cup + 1 TBSP heavy cream
  • pinch of sea salt
  • 1 tub caramel ice cream or other flavor of your choice


  • Make the Brownies: Preheat the oven to 350 degrees. Line a 9x13 pan with parchment paper.
    In a large mixing bowl, melt the chocolate and butter, in 30 second intervals, stirring between each. Let cool a few minutes. Whisk in the sugars, then the eggs and vanilla. Add flour, cocoa, and salt and whisk until combined. Batter will be thick.
    Pour batter into pan and bake for 26-28 minutes. A toothpick inserted in the center should come out with moist crumbs. The edges will look more done than the center - that's normal.
    Let brownies cool while you make the other elements, for about an hour at least.
    You could also make the brownies up to 3 days ahead. Let cool completely at room temp, then cover with foil and refrigerate until ready to finish.
  • Make the Hot Fudge: Add chocolate, sugar, evaporated milk, and vanilla to a medium saucepan. Heat over medium heat, stirring constantly, until melted. Continue heating it and stirring it until it reaches a low boil. Once it gets there, remove the pan from the heat. Stir in the tablespoon of butter.
    Let the hot fudge cool for about 30-40 minutes to thicken up.
  • Make the Homemade Caramel Sauce: Instructions, full recipe, and tips are in this blog post. Let the caramel cool for about 30 minute to thicken up, then store in the fridge until ready to use.
    Microwave in 30 second intervals, stirring between, to re-melt it after it's been refrigerated.
  • Assemble: Spread the Hot Fudge on the brownies, and add the crushed samoa cookies. If making ahead, cover this tightly with foil and refrigerate until ready to serve. If serving very soon after assembling, leave out at room temp.
    If you leave this out at room temp, the hot fudge will be more melty - if that doesn't bother you leave it out. If you want everything to hold up more, cover the pan of brownies and refrigerate for a few hours.
  • Serve + Store: Cut into slices. Serve in a bowl with a scoop of ice cream and drizzle some caramel over the top. YUM!
    Store leftover brownies, covered tightly, in the fridge for up to a week. Store leftover caramel, in an airtight container, in the fridge for up to 2 weeks.
  • Make Ahead Tips: I've already mentioned some throughout the directions here, but every element of this - the brownies, hot fudge, and caramel - can all be made ahead. The brownies can be made up to 3 days ahead and cooled, covered, and refrigerated until ready to use. The hot fudge can be made up to 5 days in advance, and kept in the fridge until ready to use. The caramel can be made up to a week in advance, and kept in the fridge until ready to use.


NOTE: If you don't have the time or energy to make every component of this at home, you can sub in any elements with their store-bought counterparts - boxed brownies, store-bought hot fudge, and store-bought caramel. However, I do challenge you to make at least one element at home - it will be SO utterly delicious - you won't regret it!
NOTE: Off-brands of the girl scout Samoa cookies can be found year-round at ALDI or in major grocery stores under the Keebler brand. You can use any cookies - doesn't have to be Samoa cookies. I think Oreos would work well here, too. You can, of course, change the ice cream flavor as well!
