You’ll love this homemade Oreo Ice Cream Cake. This allergen-friendly version is made with crunchy gluten- and dairy-free sandwich cookies, creamy dairy-free vanilla and chocolate ice creams, a rich homemade chocolate ganache, and fluffy coconut whipped topping.
A friend recently reminded me how much she loves Dairy Queen ice cream cakes, and it took me right back. When I was a teen, those cakes were everything — especially for summer birthdays. But after going gluten- and dairy-free, I assumed those nostalgic treats were off the table.
Turns out they don’t have to be. This homemade, allergen-friendly Oreo ice cream cake gives you that same layered, creamy, crunchy experience without gluten or dairy. It’s rich, indulgent, and surprisingly simple to make at home.
If you have food allergies or dietary restrictions, this cake is a dream: dairy-free, gluten-free, and full of texture and flavor. The combination of smooth ice cream layers, a dark chocolate ganache, and cookie crumb crunch makes it a crowd-pleaser.
Ice Cream Cake Ingredients
- Dairy-free vanilla ice cream — choose a creamy coconut or oat-based pint that holds up well when slightly softened.
- Dairy-free chocolate ice cream — pick a rich chocolate or dark-chocolate non-dairy option for the second layer.
- Canned coconut milk (13.5 oz) — full-fat canned coconut milk helps make a smooth ganache.
- Dairy-free dark chocolate chips (about 10 oz) — use allergy-friendly chocolate chips made without dairy.
- Gluten- and dairy-free sandwich cookies — crush about 10 cookies for the middle layer and reserve 6 for the top; save extra crumbs for garnish.
- Coconut whipped topping (Coco Whip) — thawed and chilled so it spreads easily.
- Light corn syrup (optional) — a tablespoon can help make a glossy ganache if desired.
Helpful Cake-Making Tools
- 10-inch springform pan or 10-inch round cake pan — makes removing the cake easier and helps keep the shape neat.
- Angled icing spatula — useful for spreading and smoothing each ice cream layer and the coconut whip.
- Plastic wrap or press-and-seal — lining the pan with plastic makes it simple to release the cake after freezing.
- Ice cream scoop — for placing and portioning softened ice cream into the pan.
How to make an Oreo ice cream cake from scratch

Recipe Notes and Tips
- Using a 10-inch springform pan creates a nicely round cake; a 10-inch cake pan works too.
- An angled icing spatula makes spreading cold layers much easier and gives a cleaner finish.
- Covering the pan sides with plastic wrap or press-and-seal will help you release the cake cleanly.
- Let dairy-free ice cream soften longer than traditional dairy ice cream — non-dairy pints often need extra time to become spreadable.
- The homemade ganache also works well as a sauce for other desserts, like brownies or ice cream sundaes.
- This cake can be prepared one to two days in advance for stress-free serving.

Oreo Ice Cream Cake
Ingredients
- 2 pints dairy-free vanilla ice cream
- 2 pints dairy-free chocolate ice cream
- 13.5 ounce can canned coconut milk (full fat)
- 10 oz bag dairy-free dark chocolate chips
- 1 box gluten- and dairy-free sandwich cookies — crush 10 for the middle layer and 6 for the top; extra for garnish
- 1 container coconut whipped topping (Coco Whip), thawed and chilled
- 1 tablespoon light corn syrup (optional, for ganache)
Instructions
- Place the bottom-layer ice cream (vanilla) on the counter to soften slightly so it’s spreadable.
- Heat the canned coconut milk in a medium saucepan over medium heat. Remove from the heat just before it reaches a boil.
- Meanwhile, place the dairy-free chocolate chips in a medium bowl. Add the corn syrup if using.
- Pour the hot coconut milk over the chocolate chips. Let sit 3–4 minutes, then stir until smooth. Set the ganache aside to cool slightly.
- Line the sides of a springform pan with plastic wrap. Use an ice cream scoop to place both pints of softened vanilla ice cream into the bottom of the pan. Smooth with an angled spatula.
- Pour ½ to ¾ cup of ganache over the vanilla layer and sprinkle the crushed cookie crumbs evenly on top.
- Cover the pan with plastic wrap and freeze for 20–30 minutes to set the layer.
- Allow the chocolate ice cream to soften while the first layers chill.
- Remove the pan from the freezer and spread the softened chocolate ice cream over the cookie crumb layer. Cover and refreeze for a couple of hours until firm.
- Before final assembly, stir the container of coconut whipped topping. Remove the cake from the pan and plastic wrap, then place it on a cake plate or leave it on the springform board. Use an angled spatula to “ice” the top and sides with a thin layer of Coco Whip.
- Return the cake to the freezer at least 30 minutes, then add a second, thicker layer of Coco Whip. Freeze again until firm.
- Just before serving, reheat the ganache slightly if needed so it spreads smoothly. Pour and spread an even coat over the top of the cake, letting some drip over the edges for a decorative effect.
- Crush 2–3 sandwich cookies in a bag and sprinkle the crumbs over the ganache. The cake is ready to serve. Store any leftovers covered in the freezer.
