If you love ice cream sandwiches but want something even easier (and more fun), these Frozen Cookie Sundae Bars are your new go-to. They start with a soft-baked chocolate chip cookie crust, get layered with your favorite ice cream (I used s’mores!), and freeze into the perfect sliceable treat. Frozen Cookie Sundae Bars are the ultimate make-ahead dessert for summer nights, birthday parties, or anytime you want to impress without the stress.
Do I need to chill the cookie dough before baking?
Nope! Since you’re using refrigerated cookie dough, just let it soften at room temperature and press it right into the pan.
Can I use homemade cookie dough instead?
Absolutely. Just make sure it’s enough to cover the bottom of an 8-inch square pan, and bake until golden and set.
Does the ice cream have to be completely softened?
Let it sit out for 10–15 minutes until it’s soft enough to spread evenly but not melted. This helps create smooth layers without mess.

Can I use a different size pan?
You can use a 9-inch pan, but the bars will be thinner. Adjust baking time slightly if needed.
How long do frozen cookie sundae bars last?
They’ll keep in the freezer for up to 2 weeks tightly wrapped or stored in an airtight container.
Can I make this dairy-free or gluten-free?
Yes—just swap in your favorite dairy-free ice cream and gluten-free cookie dough.
Can I add extra toppings inside the bars?
Definitely! Swirl in fudge, peanut butter, or crushed cookies between the layers before freezing.
Do I have to top with syrup?
Not at all, but it makes them feel more like a sundae. You can also add whipped cream, sprinkles, or crushed candy bars.
Picture this: it’s one of those last golden evenings of the season—patio lights are twinkling, laughter fills the air, and you’re passing around these chilled, dreamy Frozen Cookie Sundae Bars where gooey cookie meets s’mores ice cream. Perfect way to end the summer.
Buttery, sweet sugar cookie cups filled with vanilla buttercream and rainbow sprinkles!
