This playful slow cooker dessert turns a box of frozen ice cream sandwiches into an easy crowd-pleaser with almost no effort. It leans into the classic ice cream cake idea, but instead of careful layering in a pan, the crock does the work of softening everything into a scoopable, creamy treat. For National Ice Cream Sandwich Day or any relaxed summer get-together, it is a clever way to make something nostalgic, sweet, and just a little unexpected.

Serve this dessert in bowls while it is still soft and cold, with extra whipped topping, chocolate syrup, or a sprinkle of mini chocolate chips if you want to dress it up. Fresh strawberries or raspberries are especially nice alongside it because they cut the richness, and a cup of hot coffee or cold milk makes a fitting pairing.

4. Cover and cook on warm for 20 to 30 minutes, just until the layers soften and meld slightly; do not let the dessert get hot or fully melt.

6. Scoop into dessert bowls and serve.

Variations & Tips

Mint chocolate version: Use mint chocolate ice cream sandwiches if you can find them, or add a few drops of mint extract to the fudge sauce before layering for a cool, festive flavor.

Cookies and cream twist: Swap in cookies and cream ice cream sandwiches and scatter a few crushed chocolate sandwich cookies on top just before serving for extra texture.

Texture tip: Because slow cookers vary, check the dessert at the 20-minute mark. You want the sandwiches softened enough to slice or scoop, not soupy. If it loosens too much, a short freeze will bring it right back.

Make-ahead note: This dessert is excellent made ahead and frozen until firm. Let it sit at room temperature for 5 to 10 minutes before scooping so the layers soften slightly and the texture becomes creamier.
