Easy Sourdough Icebox Cake Recipe – No-Bake Summer Dessert

Beyond beating the heat, it’s also the perfect way to use up leftover starter instead of wasting it. In this article, we’ll walk you through every layer, every tip, and every substitution so your sourdough icebox cake recipe turns out perfectly every single time.

Ingredients & Substitutions

• Sourdough Graham Crackers– Store the dough in the fridge for up to 3 days before baking to long-ferment the crackers. Be sure to roll the graham crackers out very thinly before baking. Graham crackers that are too thick can make this dessert feel way too heavy.
• Homemade Whipped Cream– All you need is VERY cold heavy cream, powdered sugar, and vanilla extract to make the perfectly light and delicious whipped cream. 
• Cream Cheese – Use full-fat cream cheese, not the kind found in the tub. Be sure to allow the cream cheese to come to room temperature before whipping. 
• Berries – I love the combination of fresh strawberries, blueberries, and raspberries, especially if you make this dessert for the 4th of July, perfectly patriotic! But you can pick and choose your favorites. 
• Tip: Do not use frozen fruit, as it will release moisture while they thaw and make a mushy dessert. Thawed and dried frozen fruit won’t give the best texture either. Stick with fresh fruit when making this recipe. 
• Vanilla Extra – It adds flavor to the whipped cream. I recommend using pure vanilla extract for the best taste in this no-bake dessert.
• Powdered Sugar – Sweetens the whipped cream and helps it whip up smooth and stable.

How to Make Sourdough Icebox Cake Recipe

1. Prepare the Sourdough Graham Crackers recipe in advance to save yourself some time. I used sourdough starter discard, but you can also use an equal amount of active sourdough starter.

2. Using a hand mixer or stand mixer with a whisk attachment, whisk together the cold heavy cream, powdered sugar, and vanilla extract until stiff peaks form. Place in a separate bowl.

3. In the clean bowl with a hand mixer or stand mixer fitted with a paddle attachment, beat the softened cream cheese. Then fold in all but 1 cup of the homemade whipped cream with a rubber spatula and set this aside.

4. Spread a very thin layer of the whipped cream/cream cheese mixture on the bottom of a 9×9 pan. Arrange the sourdough graham crackers on top; break them if you need to to fit.

5. Top with ½ of the whipped cream/cream cheese mixture, ½ of the berries, and another layer of sourdough graham crackers. 

6. Repeat with another layer of the remaining whipped cream/cream cheese mixture, remaining berries, and a final layer of sourdough graham crackers.

7. Top with the reserved whipped cream, cover with aluminum foil and store in the fridge overnight. 

8. Before serving, garnish with more fresh berries, slice, and enjoy.

How to Serve Sourdough Icebox Cake Recipe

Once your sourdough icebox cake has spent enough time in the refrigerator, ideally sitting in the fridge overnight, it’s ready to serve straight from the dish. The layers of graham crackers will have fully softened into a cake-like texture, making every slice clean and creamy. Use a sharp knife to cut neat portions and a flat spatula to lift each slice beautifully onto individual plates.

For the best presentation, add a fresh layer of whipped cream and a few fresh strawberries right on the top of the cake just before serving. A light dusting of powdered sugar or a drizzle of chocolate adds an extra visual touch that makes this no-bake summer dessert truly showstopping. Serve immediately after garnishing so the real whipped cream stays perfectly fluffy and fresh.

This easy sourdough icebox cake recipe pairs wonderfully with a scoop of vanilla ice cream or a side of mixed berry compote for extra indulgence. Whether you’re serving it at a backyard gathering or a casual family dinner, this perfect summer dessert that always impresses. Its tangy depth from the sourdough base makes every bite refreshingly unique and utterly satisfying.

After serving, the cake can be stored safely in the refrigerator for up to fridge for up to 48 hours without losing its creamy texture or flavor. Simply cover it tightly with plastic wrap or press a layer of plastic wrap directly onto the surface of the cake to prevent it from absorbing any fridge odors. Stored properly, this sourdough icebox cake recipe stays fresh, firm, and absolutely delicious.

If you want to store it longer, transfer it to a freezer-safe container and freeze for up to two weeks without sacrificing quality.

When ready to enjoy, move it from the freezer to the fridge and let it thaw slowly overnight before serving.

Total Time 8 hours hrs 15 minutes mins

Ingredients

  

• 600 grams heavy cream cold 2 1/2 cups
• 50 grams powdered sugar 1/3 cup + 1 Tablespoon
• 6 grams vanilla extract 1 1/2 teaspoons
• 226 grams full-fat cream cheese softened 8 ounces
• 13-14 sourdough graham crackers 2.25 x 5 inches
• 380 grams fresh berries like chopped strawberries, blueberries and raspberries 2 cups

Instructions

 

• McKenna’s Notes: To rid of any confusion, this sourdough icebox cake consists of 3 layers of sourdough graham crackers, 2 layers of a whipped cream/cream cheese mixture, 2 layers of berries and 1 layer of whipped cream. I used about 4 ½ sourdough graham crackers (2.25 x 5 inch each) per layer. You may need to break them in order for them to fit properly.
• Prepare my Sourdough Graham Crackers recipe in advance.
• 13-14 sourdough graham crackers
• Using a hand mixer or stand mixer fitted with a whisk attachment, whisk together the cold heavy cream, powdered sugar and vanilla until stiff peaks form. Place this in a separate bowl.
• 600 grams heavy cream, cold,50 grams powdered sugar,6 grams vanilla extract
• In the clean bowl with a hand mixer or stand mixer fitted with a paddle attachment, beat the softened cream cheese. Fold in all but 1 cup of the homemade whipped cream with a rubber spatula until evenly combined. (The remaining 1 cup of whipped cream will be used as the “frosting” for this cake) Set aside.
• 226 grams full-fat cream cheese, softened
• Assemble the cake: Spread a very thin layer of the whipped cream/cream cheese mixture, a few tablespoons, on the bottom of an ungreased 9×9 pan. This helps the sourdough graham crackers from sticking to the bottom of the pan. Arrange the sourdough graham crackers on top; break them if you need to fit.
• Spread ½ of the whipped cream/cream cheese mixture on top of the graham crackers, then top with ½ of the berries. Follow with another layer of sourdough graham crackers.
• 380 grams fresh berries, like chopped strawberries, blueberries and raspberries
• Repeat this pattern again with the remaining whipped cream/cream cheese mixture, remaining berries and a final layer of sourdough graham crackers.
• For the final layer, spread the reserved cup of whipped cream over the sourdough graham crackers evenly with an offset spatula. Cover the sourdough icebox cake with aluminum foil or plastic wrap and store in the fridge overnight or up to 48 hours.
• When ready to serve, garnish with more fresh berries, slice cold and enjoy!
