The ice cream sandwich for celebrating – filled with a confetti-style sprinkle-loaded vanilla ice cream that’s sandwiched between two delicious chocolate brownie layers. It’s the perfect treat for celebrating our country’s birthday.
You can find the 13-ounce jarred sprinkles at Williams Sonoma. Please note this recipe takes two-three days to make before serving. You will need to freeze the cookie exterior overnight to prevent the ice cream from melting during assembly and freeze the ice cream. The second night you need to freeze to set the ice cream sandwich to cut the next day.
To make the cookie exterior
1 ½ sticks unsalted butter, melted and cooled slightly, plus more for the pan
1 cup all-purpose flour
¾ cup cocoa powder
¾ teaspoon baking powder
¾ teaspoon coarse salt
1 cup granulated sugar
2 large eggs
2 teaspoons pure vanilla extract
To make the Ice cream
2 cups whole milk
1 cup heavy cream
4 large egg yolks
⅔ cup sugar
1 ½ teaspoons vanilla extract
1 13-ounce jar Williams Sonoma Chocolate Dessert Sprinkle Mix
Heat oven to 350˚F. Butter two 9 by 13-inch baking sheets and line them with parchment paper.
In a medium bowl, whisk together the flour, cocoa powder, baking powder and salt. Using an electric mixer fitted with a paddle attachment, combine the butter and sugar mixing until creamy. One at a time, add the eggs and beat until smooth. Add the vanilla and combine. Add the flour mixture in three equal batches and beat until well combined. The batter should be thick and slightly sticky.
Divide the batter evenly in each pan, smooth to a thin even layer, and leave a small border of parchment paper around the edge of the pan. Place in the oven and bake until cake is set, 10 to 12 minutes. Transfer the pans to cooling racks. When completely cooled place the pans in the freezer and freeze overnight.
Make the ice cream:
Fill a very large mixing bowl with ice and add a smaller metal bowl into the center.
Combine the milk and cream in a medium saucepan, cooking over medium-low heat until small bubbles form around the edge of the pan. Meanwhile in a medium bowl, add the egg yolks and sugar whisking until the yolks become pale yellow.
Slowly whisk in the hot milk mixture into the egg mixture. Start by adding small amounts to temper the eggs. When mixed together, pour back into the pot and cook over low heat, stirring constantly with a wooden spoon, until the custard lightly coats the back of the spoon, about 10 minutes.
Strain the custard through a sieve into the bowl that is in the center of the ice. Stir occasionally to cool. When cooled add the vanilla and whisk in then refrigerate overnight.
The next day churn the ice cream. When the ice cream is almost done add 1-1/2 cups of the sprinkle and finished churning to start the assembly.
Remove the cookie exteriors from the freezer. Add the ice cream evenly over the top of one of the cookies remaining in the pan. Using an offset spatula to spread the ice cream into an even layer. Place the remaining piece of cookie on the ice cream with the top facing down, and the flat side up, to make a large ice cream sandwich. Gently press together. Still in the pan, immediately wrap it well in plastic wrap and freeze until firm, at least 8 hours or overnight.
Add ½ cup of sprinkles to a flat dish. Remove the large ice cream sandwich from the freezer and take off the plastic wrap and parchment. Place on a cutting board and trim about ¼ inch off of each edge and then cut into 12 smaller sandwiches. Dip the edges of each side in the sprinkles and then wrap each sandwich well in plastic wrap and freeze until firm for 2-4 hours until ready to serve. Makes 12 ice cream sandwiches.
