This easy National Dog Day dessert is the kind of playful, low-effort treat that works when you need something fun for a summer get-together but do not want to spend the whole afternoon baking. Using frozen ice cream sandwiches as the base gives you instant layers and structure, while a few simple toppings turn them into a creamy, sliceable dessert that feels a little nostalgic and a lot crowd-pleasing.
Serve this frozen dessert straight from the freezer with fresh fruit, a drizzle of chocolate or caramel sauce, or a few extra cookies crumbled on top. It also pairs well with iced coffee after dinner, or with a simple bowl of berries if you want something a little lighter alongside the rich, creamy layers.
4-Ingredient Oven Baked National Dog Day Dessert
Servings: 8
Ingredients
12 solid unwrapped frozen ice cream sandwiches
Directions
1. Line the bottom of a 9x13-inch oven-safe glass baking dish with 6 solid unwrapped frozen ice cream sandwiches, placing them snugly side by side to form the first layer.
2. Spread half of the whipped topping over the ice cream sandwiches in an even layer, then drizzle half of the chocolate syrup over the top.
3. Sprinkle half of the crushed chocolate sandwich cookies over the whipped topping, then add the remaining 6 ice cream sandwiches on top to make a second layer.
4. Finish with the remaining whipped topping, the rest of the chocolate syrup, and the remaining crushed cookies, spreading and sprinkling everything evenly across the top.
5. Cover the dish and freeze for at least 2 hours, or until firm enough to slice cleanly. Cut into squares and serve immediately.
Variations & Tips
Mint chocolate version: Swap the regular chocolate sandwich cookies for mint chocolate sandwich cookies if you want a cool, fresh flavor that feels especially nice in warm weather.
Make-ahead tip: This dessert is perfect to assemble the night before a party. I like to cover it tightly and let it freeze overnight so slicing is quick and clean the next day.
Extra topping idea: If you want a little more texture, add mini chocolate chips or chopped peanuts right before serving. Waiting until the end helps keep them crisp.
Neater slices: Let the dessert sit at room temperature for 5 to 10 minutes before cutting. That short rest makes it much easier to get tidy squares without smashing the layers.
