My grandmother made this 4 ingredient summer dessert every August to beat the intense heat. Creamy, nostalgic, and the absolute easiest sweet treat to throw together for a backyard crowd.

This 4-Ingredient Ice Cream Sandwich Cake layers soft ice cream sandwiches with fluffy whipped topping, rich chocolate syrup, and sweet mini chocolate chips. Frozen until firm, this effortless no-bake dessert slices into cool, decadent squares that are perfect for summer parties, birthdays, or easy family treats.

4-Ingredient Ice Cream Sandwich Cake

Ingredients:

Step-By-Step Directions:

1. First layer: Line the bottom of a 9×13-inch glass baking dish with 6 ice cream sandwiches in a single, snug layer (trimming as needed to fit).

2. First topping: Spread half of the thawed whipped topping evenly over the bottom layer of ice cream sandwiches, then drizzle generously with chocolate syrup.

3. Second layer: Arrange the remaining 6 ice cream sandwiches on top to form a second layer, then spread the rest of the whipped topping over the top.

4. Garnish: Drizzle more chocolate syrup over the whipped topping layer and sprinkle evenly with the mini chocolate chips.

5. Freeze and serve: Cover the dish tightly and freeze for at least 4 hours, or until firm. Let rest at room temperature for 5 to 10 minutes before slicing into squares and serving chilled.
