Pro Tips for Rhubarb and custard ice cream sandwiches
- Chill Everything First: Ensure your mixing bowl and ice cream maker are chilled beforehand. This helps the rhubarb and custard ice cream set up beautifully.
- Don’t Over-Churn: Keep an eye on the ice cream while churning; over-churning can lead to a grainy texture instead of the creamy goodness you want for your sandwiches.
- Perfect Cookie Size: Aim for uniform cookie sizes when dropping them onto the baking sheet. This ensures even baking and balanced rhubarb and custard ice cream sandwiches.
- Cooling Time Matters: Let the cookies cool completely before assembling. Warm cookies can melt the ice cream, making a delightful mess instead of a perfect treat.
- Store Properly: If freezing assembled sandwiches, wrap each in parchment paper before placing them in an airtight container to keep them fresh and prevent freezer burn.
How to Store and Freeze Rhubarb and custard ice cream sandwiches

Fridge: Keep your ice cream sandwiches in an airtight container for up to 5 days to maintain their freshness and flavor.
Freezer: For longer storage, wrap each sandwich individually in plastic wrap and place them in a freezer-safe bag. They’ll stay delicious for up to 2 months.
Thawing: When you’re ready to enjoy your Rhubarb and custard ice cream sandwiches, remove them from the freezer and let them sit at room temperature for about 10 minutes before serving.
Cookies: If you have leftover cookie dough, you can freeze it in a log shape. Wrap tightly in plastic wrap for up to 3 months; slice off pieces when you’re ready to bake!
Rhubarb and custard ice cream sandwiches Your Way
Feel free to unleash your creativity and make this treat truly yours with delightful twists!
- Vegan: Substitute heavy cream and milk with coconut cream and almond milk for a dairy-free delight. The rich coconut flavor pairs beautifully with rhubarb, offering a refreshing taste that everyone can enjoy.
- Sugar-Free: Use erythritol or a similar sugar substitute in both the ice cream base and cookies. This swap keeps the sweetness while being kinder to your waistline, without sacrificing that classic indulgent experience.
- Fruit Fusion: Blend in 1/2 cup of strawberries or raspberries into the ice cream base for an extra fruity layer. The tartness from these berries will create a vibrant contrast with the rhubarb, making each bite burst with flavor.
- Nutty Crunch: Add 1/2 cup of chopped nuts, like pecans or walnuts, into the cookie dough for added texture. The crunch complements the softness of the ice cream, elevating the overall experience to new heights!
- Spicy Kick: Incorporate 1/2 teaspoon of ground ginger or cinnamon into the cookie mixture for a warm spice twist. This aromatic addition adds depth and warmth, making each sandwich even more comforting.
- Chocolate Drizzle: Melt dark chocolate and drizzle it over the assembled sandwiches for a decadent finish. This luscious touch brings a rich contrast to the sweet and tangy flavors of rhubarb and custard.
- Savory Option: Mix in a pinch of sea salt into the ice cream base for an unexpected savory note that enhances all flavors. A touch of salt can make sweet treats pop in delightful ways!
Make Ahead Options
Preparing Rhubarb and custard ice cream sandwiches is a delightful way to simplify your dessert game while impressing family and friends. You can whip up the ice cream base up to 24 hours in advance by combining 2 cups of heavy cream, 1 cup of whole milk, 3/4 cup of sugar, 1 tablespoon of vanilla extract, and 1 cup of cooked rhubarb puree. Churn the mixture in your ice cream maker, transfer it to a container, and let it freeze for at least 2 hours. As for the cookies, you can prepare the dough a day ahead; simply cream together 1 cup of softened butter with both sugars, incorporate 2 large eggs, and mix in the dry ingredients before chilling the dough.

Rhubarb and custard ice cream sandwiches Recipe FAQs
What type of rhubarb should I use for the ice cream?
For the best flavor in your rhubarb and custard ice cream sandwiches, opt for fresh, bright red rhubarb stalks. They’re sweeter and more tender than green varieties. If fresh isn’t available, frozen rhubarb works too—just thaw and drain any excess moisture before pureeing.
How should I store leftover ice cream sandwiches?
If you have any leftovers (though they’ll be hard to resist!), wrap each sandwich tightly in plastic wrap or place them in an airtight container. They will keep well in the freezer for up to two weeks. Be sure to separate layers with parchment paper to prevent sticking!
Can I make these cookies gluten-free?
Absolutely! To make gluten-free rhubarb and custard ice cream sandwiches, substitute all-purpose flour with a 1: 1 gluten-free baking blend. This will replicate the texture nicely while accommodating dietary restrictions, ensuring everyone can enjoy this delightful treat!
How long does it take to prepare these ice cream sandwiches?
The total time for making these delicious treats is about 180 minutes, which includes 30 minutes of active prep time while the ice cream churns and the cookies bake. Plan ahead so you have ample time for freezing your ice cream—at least 2 hours after churning!
What if my cookies spread too much while baking?
If your cookies spread excessively during baking, it could be due to the butter being too soft or not enough flour being added. Make sure your butter is just softened, not melted, and measure your flour accurately using the spoon-and-level method. For a firmer cookie, chill the dough for about 30 minutes before baking.
How many servings does this recipe yield?
