The Ultimate Ice Cream Sandwich


Brownie Layer

  • 10 tbsp unsalted butter, melted
  • 1 1/4 cups sugar
  • 3/4 cups unsweetened cocoa powder
  • 1/2 tsp salt
  • 2 tsp vanilla extract
  • 1 large egg, room temp

Cookie Layer

  • 4 tbsp unsalted butter, room temp
  • 1/4 cup light brown sugar, lightly packed
  • 2 tbsp sugar
  • 1/2 tsp vanilla extract
  • 1 large egg, room temp
  • 1/2 cup flour
  • 1/2 tsp salt
  • 1/2 tsp baking soda
  • 1 cup semi-sweet chocolate chips

Ice Cream

  • 1 quart Oreo ice cream, softened


  • Preheat the oven to 350 F.  Fully line 2 9"x9" baking pans with parchment paper in both directions so you can easily remove the brownie and cookie layer from the pans.  I had the parchment paper coming up over the edge of the pan, creating a handle to lift the brownie/cookie out with.   (If you don't have 2 pans, just bake each layer separately.)

Brownie Layer

  • In a medium saucepan, melt the butter over medium-high heat.  Once it's melted, turn off the heat and whisk in the sugar and cocoa powder.
  • Add the salt, vanilla and egg and whisk to combine.  The batter will be nice and glossy.  
  • Lastly, add in the flour and mix well to fully incorporate it into the batter.
  • Pour the batter into the prepared pan and bake for 23 minutes.

Cookie Layer

  • Mix together the butter and sugar using a hand held mixer.  Beat the mixture until it's light and fluffy.  
  • Next, add in the vanilla and egg and mix well to combine.
  • In a small bowl, whisk together the flour, salt and baking soda.  Then slowly add the dry ingredients into the wet ingredients and mix to combine.  
  • Lastly, fold in the chocolate chips.  Pour the batter into the prepared baking pan.  It's a very thin layer of sticky cookie dough, so you'll need to use a spatula (and your clean fingers) to spread it evenly.  
  • Bake for 12-13 minutes.

Putting it All Together...

  • Once the brownie and cookie layers have COMPLETELY cooled, it's time to assemble the ice cream sandwich.
  • Carefully remove the brownie layer and flip it over back into a freshly parchment paper lined pan.   You want the "pretty" side of the brownie layer to be facing outward.  Next, evenly spread the ice cream all over the brownie layer.  Lastly, top with your cookie layer!  Cover tightly with aluminum foil and freeze for 4 hours or until it's frozen solid.  
  • Remove the big square ice cream sandwich from the pan and cut into 16 squares - enjoy!
