This isn’t your average cake! This Sourdough Angel Food Cake features a vibrant raspberry-lemon swirl and a delicate, fluffy texture.
Made with sourdough discard and topped with fresh strawberries and homemade whipped cream, it’s the ultimate farmhouse dessert for spring.
Why Sourdough Discard in Angel Food Cake?
You might be wondering what a sourdough starter is doing in a delicate cake like this! Well, it’s a bit of a farmhouse secret. The natural tang from the discard perfectly balances the sweet, sugary meringue, so the cake isn’t cloying. It also gives the crumb just a bit more “sturdiness” than a store-bought mix. This is important because when we start layering in those heavy strawberries and fresh whipped cream, we need a cake that can hold its own without falling apart!
The Secret to that Raspberry Lemon Swirl
The heart of this cake is that bright, glossy raspberry reduction. By simmering the berries with a bit of cornstarch and lemon, we’re cooking out the extra moisture that would normally weigh down a light batter.
You have to be patient here… Make sure your raspberry mixture is completely cooled before you drizzle it into the pan. If it’s even a little bit warm, it will deflate those beautiful egg whites you worked so hard to whip up, and we want this cake to be as light as a cloud.
Mastering the Meringue: My Top Tips for a High Rise
If you’re new to angel food cake, don’t let the egg whites intimidate you! To get that massive, airy rise, make sure your egg whites are at room temperature before you start whisking. Cold whites won’t hold the air nearly as well.
Just remember the “Golden Rule” of angel food cake: Cool it upside down! As a baker who has seen a few cakes fall in my time… I promise this step is vital. Cooling it upside down stretches the delicate structure while it sets, preventing the cake from collapsing under its own weight as it cools.
A spring pantry staple
FAQ: Your Questions Answered
Can I use frozen raspberries? Absolutely! Just keep an eye on them while they simmer. Frozen berries can release a bit more juice, so you might need an extra minute or two on the stove to make sure the mixture gets thick and glossy.
Do I really need a special Angel Food Cake pan? Ideally, yes. You want a tube pan that is ungreased so the batter can literally “climb” the walls of the pan as it bakes. If it has the little “feet” on top for cooling upside down, even better!
What if I don’t have a sourdough starter? This recipe is really built around the texture and acidity of that sourdough discard… It’s what gives it character. If you don’t have a starter yet, you can find my guide on how to start starter here, but for this specific cake, you’ll definitely want that discard!
How should I store this? Because we’re using fresh, real whipped cream and juicy strawberries, this cake is best enjoyed right away. If you do have a few slices left over, tuck them into the fridge. They’ll stay delicious for about 2 days!

Sourdough Angel Food Cake with Raspberry Lemon Swirl
Equipment
- 10-inch Angel Food Tube Pan (ungreased)
- Stand mixer or hand mixer
- Large rubber spatula (for gentle folding)
Ingredients
For the Raspberry Lemon Swirl
- 1 1/2 cups fresh or frozen raspberries
- 2 tbsp butter
- 1 1/4 tsp lemon juice
- 1 tsp cornstarch
For the Sourdough Cake Batter
- 1 cup egg whites approx. 7–8 large eggs, room temperature
- 1 tsp cream of tartar
- 3/4 cup granulated sugar divided
- 1/2 cup sourdough discard
- 1 tsp vanilla extract
- 1 1/2 tsp lemon zest optional
- 1 cup cake flour sifted
- 1/4 tsp salt
For the Topping & Filling
- 2 cups heavy whipping cream
- 1/4 cup granulated sugar
- 1.5 lbs fresh strawberries sliced
Instructions
- Prepare the Swirl: In a small saucepan over low heat, combine raspberries, butter, lemon juice, and cornstarch. Simmer for 5–8 minutes, mashing the berries as they soften, until the mixture is thick and glossy. Strain through a sieve to remove seeds if desired. Cool completely before using.
- Prep the Oven: Preheat your oven to 350°F (175°C). Ensure your tube pan is bone-dry and completely ungreased.
- Whip the Meringue: In a clean bowl, beat egg whites until foamy. Add cream of tartar. Slowly stream in 1/2 cup of the sugar while beating on medium-high until stiff, glossy peaks form.
- Incorporate Aromatics: Gently fold the sourdough discard, vanilla, and lemon zest into the egg white mixture. Work slowly to keep the air in the whites.
- Fold in Dry Ingredients: Sift the cake flour, salt, and the remaining 1/4 cup of sugar together. Fold this into the egg mixture in three separate additions. Stop as soon as no flour streaks remain.
- The Swirl: Spoon half the batter into the tube pan. Drizzle 2–3 tablespoons of the cooled raspberry mixture over the batter and swirl gently with a butter knife. Add the remaining batter, top with the rest of the raspberry mixture, and swirl one more time.
- Bake: Bake for 35–40 minutes or until the top springs back when lightly touched.
- The Cool Down: Immediately invert the pan (place it upside down on its “feet” or over a glass bottle) and let it cool completely for at least 2 hours.
- Assemble: Once cool, run a knife around the edges to remove from the pan. Slice the cake in half horizontally. Whip the heavy cream with 1/4 cup sugar until stiff. Layer the middle with whipped cream and half the strawberries. Top with the second cake half, more whipped cream, and the remaining berries.
