If you love fruit‑filled cakes that are not too heavy, this sour cherry sponge cake is a perfect choice. The batter is based on whipped egg whites, which keeps the texture tall and soft, while the cherries add a pleasant tart flavor in every bite. You can use fresh or frozen sour cherries, so it works in any season and makes a great everyday dessert for the whole family.
How to prepare the sour cherries for baking
Preparing the sour cherries correctly helps you avoid a soggy cake and keeps the fruit evenly distributed in the batter. If you use fresh cherries, rinse them under cold water, remove the stems, then carefully pit them, making sure no pit fragments remain. Let the cherries drain in a sieve or pat them dry gently with paper towels to remove excess moisture. For frozen cherries, thaw them in a bowl, then drain the juices very well so they do not water down the batter. You can leave the cherries as they are or cut larger ones in half if you prefer smaller pieces. Once the cherries are ready, you will add a part of them directly into the batter and arrange the rest on top before baking, which gives a nice, rustic look to the cake.
Secrets for getting firm, airy egg whites
The texture of this sponge cake depends a lot on how well you whip the egg whites, so it is worth taking a little care with this step. Use a clean, dry bowl with no traces of grease, because fat can prevent the egg whites from whipping properly. Start mixing on medium speed until the whites become foamy, then gradually increase the speed until they turn into a thick, stable foam with stiff peaks that stand up straight. Adding the sugar slowly while whipping helps create a glossy, dense meringue that holds air better in the oven. Be careful not to over‑whip, as the mixture may become dry and grainy. When you fold the yolk mixture and flour into the whites, use gentle movements so you do not lose the air you worked to create.
Baking time and how to check if the cake is ready
Even though the indicated baking time is about 20–25 minutes at 350°F (175°C), every oven behaves a little differently, so it is helpful to know what to look for. During baking, the sponge will rise and turn a light golden color on top, and the cherries will release some of their juices. Try not to open the oven door during the first 15 minutes so the cake does not deflate. Toward the end of the baking time, gently press the center of the cake with a fingertip; it should spring back when it is ready. You can also insert a toothpick into the middle, avoiding the cherries; it should come out clean or with a few dry crumbs. If the toothpick is wet with batter, continue baking for a few more minutes, checking again as needed.
Storage tips and variations with other fruits
This sour cherry sponge cake keeps well at room temperature for a couple of days if you store it correctly. Place the cooled pieces in an airtight container or cover the pan with plastic wrap so the crumb does not dry out. If your kitchen is very warm, you can refrigerate the cake, then bring it back to room temperature before serving for the best texture. The recipe is also quite flexible when it comes to fruit. You can replace the sour cherries with sweet cherries, berries, apricots, or plums, as long as you adjust the sweetness to taste. Just make sure any fruit you use is well drained and not too juicy, so the batter stays light. This makes the recipe a great base for many seasonal cakes using the same simple method.

Frequently Asked Questions
Yes, you can use sweet cherries, but the overall flavor will be less tangy. To balance the sweetness, you may reduce the sugar slightly or add a bit of lemon zest to the batter so the cake still has a fresh, bright taste.
Yes, you can bake the batter in a round pan of similar volume, but the baking time may change slightly. Keep the same oven temperature and start checking for doneness a few minutes earlier, then adjust as needed until the top is springy and a toothpick comes out clean.
You can definitely add a teaspoon of vanilla extract or some grated lemon zest for extra flavor. These additions pair beautifully with cherries and give the cake a delicate aroma, without changing its texture or baking time.
