Homemade Ice Cream Sandwiches: Soft Cookies, No Spreading
Rolling and Cutting Even Cookies
Roll one disc between two sheets of parchment paper to an even 1/4-inch thickness. Lifting the top parchment occasionally helps prevent sticking. Use a 2-inch round cutter to stamp out as many rounds as possible. Transfer them to a parchment-lined baking sheet, spacing them an inch apart.
Reroll the scraps once — any more than that, and the dough gets tough from overworking. You should get about 24 cookies total from both discs. If you have extra dough, bake them as a snack.
Bake at 350°F (177°C) for 8 to 10 minutes. The edges should be set and lightly golden, but the centers will look slightly underdone and puffy. That's exactly what you want. They'll continue to set as they cool on the pan for 5 minutes, then transfer to a wire rack. The centers will sink slightly, creating a flat surface that hugs the ice cream.
The Ice Cream Layer: Even and Firm
While the cookies cool, prepare the ice cream layer. Let 1 quart of vanilla ice cream sit at room temperature for 10 to 15 minutes until it's soft but not melted. Spread it evenly into a 9x13-inch baking dish lined with plastic wrap. Aim for a 3/4-inch thickness — any thicker and the sandwich becomes unwieldy, any thinner and it disappears between the cookies.
Freeze the slab until completely firm, at least 4 hours. Overnight is better. Once solid, use the same 2-inch round cutter to stamp out ice cream rounds. Dip the cutter in hot water and dry it between cuts for clean edges. Work quickly, returning the slab to the freezer if the ice cream starts to soften.
Assembly: Speed and Gentleness
Pair up cookies of similar size. Place one cookie flat side up, top with an ice cream round, and press the second cookie on top, flat side down. Gently squeeze — don't smash — to adhere. The ice cream should just reach the edges of the cookies.
Wrap each sandwich individually in plastic wrap. This prevents freezer burn and keeps the cookies from absorbing ice crystals. Freeze for at least 1 hour before serving. When you're ready, let the sandwich sit at room temperature for exactly 2 minutes. That's the sweet spot where the cookie softens slightly and the ice cream is scoopable but not melting.
Variations to Try
Once you have the technique down, experiment with flavors. Use chocolate cookie dough with mint chip ice cream. Add a thin layer of melted chocolate between the cookie and ice cream for a magic shell effect. Roll the edges of the sandwich in sprinkles, crushed peanuts, or mini chocolate chips immediately after assembling.
For a gluten-free version, substitute a 1:1 gluten-free flour blend. The cookies will be slightly more delicate, so handle them gently. For dairy-free, use vegan butter and a coconut milk-based ice cream. Always consult a qualified professional for personal dietary decisions.
