Last month, we were supposed to kick off the summer with a camping trip with some friends. The weather, however, had other plans, and a weekend of cool, rainy weather put the kibosh on things. So much for lounging in the hammock and making pizzas and s’mores over the fire.
The canceled trip meant that all of our s’more supplies went back into the pantry, destined to wait for a sunny weekend. However, I couldn’t stop thinking about s’mores. Toasty, caramelized marshmallow. Sweet, melty chocolate. Crunchy graham crackers. I needed s’mores in my life! (Yes, I suppose we could have had a bonfire in the backyard. But that seemed too easy. Plus, it was raining, remember?)
And that’s when it hit me: S’more ice cream sandwiches. Why hadn’t I thought of this earlier? Graham crackers would be the perfect vehicle to get toasted marshmallow ice cream to my mouth. But what about the chocolate? In a s’more, the chocolate melts through the marshmallow, and ideally, every bite contains some of each ingredient. That ruled out chocolate chips (no way to guarantee that you’ll get some in each bite) and Hershey bars (too crunchy). Milk chocolate ganache would be the perfect option. I could swirl it through the ice cream after churning it, so each bite would have the perfect amount of chocolate and marshmallow. Brilliant!
I turned to the internet for a marshmallow ice cream recipe, and after reading through a few, decided to use this one from Completely Delicious. I liked the fact that it was a custard-based ice cream, so it would hold up well between the graham crackers and not melt instantly. I used a 9″ x 13″ pan for the ice cream, which gave me 15 fairly thick sandwiches, so I think you could use a jelly roll pan if you wanted thinner sandwiches or a greater yield.
I ended up with a lot of extra ganache, so I’m halving the amount in the directions below. You could double it if you want lots of chocolate sauce (or if you want to eat extra ganache on extra graham crackers).
The ice cream is really rich. So rich, in fact, that I was a little concerned that the sandwiches would be over the top. And then I was afraid that I’d added too much ganache and overpowered the marshmallow flavor.
Thankfully, everything mellowed in the freezer, and the final result was just right. The sandwiches taste just like a s’more, and you don’t have to worry about campfire smoke getting in your eyes while you eat them. I guess I should be glad that we canceled that camping trip after all. 😉
S’mores Ice Cream Sandwiches
For the ice cream:
5 large egg yolks
1 cup heavy whipping cream
2 cups whole milk (I used half and half, since that’s what’s in my fridge.)
1/3 cup sugar
1 teaspoon vanilla
7 ounces of marshmallows (I used a combination of large and mini marshmallows. The original recipe says 9 jumbo “campfire” marshmallows.)
For the ganache:
3 ounces milk chocolate chips
1 1/2 ounces heavy whipping cream
Graham crackers, broken into squares (I used 15 large crackers.)
To make the ice cream, combine the sugar, salt and whole milk in a medium saucepan. Cook over medium heat until the milk mixture begins to steam and is heated through, but do not boil it.
While the milk is heating, beat the egg yolks together in a glass measuring cup. Gradually pour the heated milk mixture into the egg yolks, whisking constantly. When you’ve added about half to two-thirds of the warm milk to the egg yolks, pour the egg-milk mixture back into the saucepan, whisking constantly.
Cook the mixture over medium heat until it thickens and coats the back of a metal spoon, stirring often. Pour the cooked custard through a fine mesh strainer into a large bowl. Stir in the cream and vanilla.
Line a baking sheet with aluminum foil and spray the foil with cooking spray. Place the marshmallows on the prepared sheet. Put the sheet under the broiler and broil for a few minutes, keeping a close eye on them so they don’t burn. When the marshmallows are brown on top, remove the pan from the oven and stir the marshmallows around so the untoasted insides are exposed. Put the pan back under the broiler until the tops of the marshmallows are browned. Remove from the oven, stir one more time and place them under the broiler again.
When the top of the marshmallows are toasted, scrape them into the bowl with the ice cream mixture. Use an immersion blender to puree the mixture until it is smooth, and then chill the mixture in the refrigerator until it is completely cold.
Churn the ice cream in an ice cream maker according to the manufacturer’s instructions.
While the ice cream is churning, prepare the ganache. Place the chocolate chips in a small, heatproof bowl. In a small saucepan, bring the cream to a boil. Pour the hot cream over the chocolate chips and let it sit for a few minutes, then whisk until smooth. Let cool to room temperature. (Ganache will thicken as it cools.)
When the ice cream has finished churning, line a 9″ x 13″ pan with waxed paper. Spread the about half of the churned ice cream in the pan, and then drizzle the ganache on the ice cream. Spread the rest of the ice cream over the ganache and use a butter knife to swirl the ganache through the ice cream. Place the pan in the freezer and freeze until solid, at least two hours.
When the ice cream has frozen completely, remove the pan from the freezer. Using your graham crackers as a template, cut the ice cream into squares that are slightly smaller than the crackers. Use a metal spatula to scoop the ice cream squares out of the pan and sandwich each square between two graham crackers. Place the sandwiches in the freezer and freeze until firm.
