I’ll take a good store bought ice cream sandwich any day. In fact, I like them so much I’ve made an entire ice cream cake with them. However, making homemade ice cream sandwiches is even more fun because you can experiment with different bases and fill them with whatever type of ice cream you feel like eating. In this case, that ice cream was homemade chocolate mint.
The base is a thin brownie that’s neither too crunchy nor too firm when frozen. I found the original recipe in the 2002 July/August issue of Cook’s Illustrated, but I changed the technique somewhat. They cut their brownie into rounds (and the ice cream, too) and they also use a 17×11 inch jelly-roll pan to bake the cookie base. Since I couldn’t find my 17×11 inch pan, I experimented and made the base by diving it among two 9 inch square pans. I also tried spreading in a 9×13 inch pan. As expected, the 9×13 inch pan made too thick of a base, while dividing between the two 9 inch pans yielded a thinner crust that was easier to bite into. So if you don’t have the 17×11 inch pan, go with the two 9 inch pans. And of course there’s always the option of halving, in which case you’d want to use just one 9 inch square pan.
- 1 cup plus 2 tablespoons well-stirred and aerated flour (or weigh out exactly 5 oz)
- 1/2 cup Dutch process or Hershey’s Extra Dark cocoa powder
- 1/4 teaspoon salt
- 1/8 teaspoon baking soda
- 2 large eggs
- 2/3 cup granulated sugar
- 1/4 cup chocolate syrup
- 1/2 teaspoon vanilla extract
- 8 tablespoons unsalted butter, melted
- 2 pints of your favorite ice cream.
- Preheat oven to 350.
- Line an 11×17 inch jelly-roll pan or two 9 inch square pans with nonstick foil.
- In a medium size bowl, thoroughly mix together the flour, cocoa powder, salt and baking soda.
- In a large mixing bowl using a handheld electric mixer, beat the eggs and sugar for about a minute. Beat in the chocolate syrup, vanilla extract and butter until mixture turns light brown. With a heavy rubber scraper or a spoon, stir in the flour mixture until incorporated.
- Pour batter into lined pan and bake 10-12 minutes or until cakes seem firm and set. Remove from oven and let cool completely. Lift from pan and set cookie on a large cutting board.
- Cut the cookie lengthwise to make two long rectangles, then cut cross-wise to make 4 rectangles (this makes them eaiser to work with). Place one of the rectangles on a big sheet of plastic wrap and spoon ice cream evenly over the top. Cover with second rectangle and press down slightly. Wrap tightly in plastic. Repeat with second set of rectangles. Set on a baking sheet and put in the freezer overnight or until very firm.
- Using a large knife, trim the sides to give the sandwiches a clean edge. Cut each section into 4 rectangles.
