Introduction

If you love fresh strawberries, soft sponge cake, and easy homemade desserts, this Strawberry Sponge Cake on a Baking Tray is a recipe you will want to make again and again. This simple German-style strawberry cake combines a light, fluffy sponge with sweet, juicy strawberries for a dessert that looks beautiful and tastes wonderful.

The best part is that this recipe uses a cup-measuring method, so you do not need a kitchen scale. With a few everyday ingredients, you can prepare the batter quickly and bake a delicious cake that is perfect for family gatherings, afternoon coffee, birthdays, or weekend treats.

Although the preparation takes only about five minutes, the cake still needs time in the oven to bake properly. The result is a tender, golden sponge topped with the fresh flavor of strawberries.

Ingredients

For the sponge cake:

3 large eggs
1 cup granulated sugar
1 cup all-purpose flour
1 teaspoon baking powder
1 teaspoon vanilla extract
1/4 cup milk
1/4 cup vegetable oil or melted butter
A pinch of salt

For the strawberry topping:

2 cups fresh strawberries, washed and sliced
2 tablespoons sugar, optional
1 teaspoon lemon juice, optional

For decoration (optional):

Powdered sugar for dusting
Whipped cream for serving
Fresh strawberry slices for garnish

Cup measurement: Use a standard 240 ml measuring cup. The recipe is designed for a medium-sized baking tray, approximately 30 × 40 cm, although a slightly smaller tray will produce a thicker cake.

Instructions

Step 1: Prepare the baking tray

Preheat your oven to 180°C (350°F). Line a baking tray with parchment paper or lightly grease it with butter or oil.

Wash the strawberries, remove their green tops, and slice them into thin pieces. If your strawberries are particularly tart, gently toss them with the optional sugar and lemon juice. Set them aside while preparing the batter.

Step 2: Beat the eggs and sugar

Crack the eggs into a large mixing bowl. Add the granulated sugar and whisk for approximately 3–5 minutes, until the mixture becomes pale, fluffy, and slightly thick.

This step is important because incorporating air into the eggs helps give the sponge cake its light texture.

Step 3: Add the wet ingredients

Add the vanilla extract, milk, and vegetable oil or melted butter. Mix gently until everything is combined.

If using melted butter, allow it to cool slightly before adding it to the eggs.

Step 4: Incorporate the dry ingredients

In a separate bowl, combine the flour, baking powder, and salt.

Sift the dry ingredients into the egg mixture. Fold gently with a spatula or whisk just until no dry flour remains. Avoid overmixing, as this can make the sponge dense instead of fluffy.

Step 5: Pour the batter into the tray

Spread the batter evenly over the prepared baking tray. Arrange the sliced strawberries across the top, leaving a little space between the pieces.

If the strawberries are very juicy, pat them dry with a paper towel before adding them to the batter. This helps prevent excess moisture from affecting the cake’s texture.

Step 6: Bake the cake

Place the tray in the preheated oven and bake for approximately 20–30 minutes, depending on the thickness of the batter and your oven.

The cake is ready when it is lightly golden and a toothpick inserted into the center comes out clean or with a few dry crumbs.

Avoid opening the oven door too early, as a sudden temperature change can cause the sponge to sink.

Step 7: Cool and decorate

Remove the cake from the oven and let it cool in the tray for about 10–15 minutes.

Once cooled, dust the top with powdered sugar or serve each piece with a spoonful of whipped cream. You can also add a few fresh strawberry slices for an attractive finish.

Cut into squares and serve.

Cooking Method

This recipe uses the traditional oven-baking method, which allows the sponge to rise evenly while developing a delicate golden crust.

The eggs and sugar are beaten together to incorporate air, while the baking powder provides additional lift. The flour gives the cake structure, and the milk and oil help keep the crumb tender and moist.

The strawberries soften slightly during baking, releasing their fruity aroma and creating a delicious contrast with the sweet sponge.

For the best results, mix the batter gently and distribute the strawberries evenly across the tray.

The History of Strawberry Sponge Cake

Strawberry cake is inspired by a long tradition of combining seasonal fruit with simple cakes and pastries. In Europe, sponge cakes became popular because their light texture made them an excellent base for cream, fresh fruit, and preserves.

In Germany, fruit cakes known as Obstkuchen are especially popular during spring and summer. They are commonly served with coffee during afternoon gatherings and family celebrations.

Strawberries are among the most beloved fruits used in these desserts because of their bright color, natural sweetness, and refreshing flavor.

A tray-baked strawberry sponge is a practical variation of these traditional cakes. Instead of assembling multiple layers, the batter is baked in one tray, making the dessert easy to portion and share.

Formation and Texture of the Cake

The secret to a successful strawberry sponge cake lies in how the batter is prepared.

The eggs: Beating the eggs with sugar creates a light mixture that helps the cake rise.

The flour: Flour provides the structure that holds the sponge together.

The baking powder: This helps the batter expand during baking, producing a soft and airy crumb.

The milk and oil: These ingredients contribute moisture and tenderness.

The strawberries: Fresh strawberries add natural fruitiness and a pleasant contrast to the soft cake.

As the cake bakes, the batter sets around the fruit, creating a tender sponge with little pockets of strawberry flavor. Once cooled, the cake should be soft enough to cut easily while remaining sturdy enough to serve in neat squares.

Helpful Tips for the Perfect Strawberry Cake

Use room-temperature eggs. They generally whip more easily and combine well with the other ingredients.
Choose ripe strawberries. Sweet, fragrant berries give the cake its best flavor.
Do not overmix. Fold the flour into the batter gently to preserve its airy texture.
Avoid excessive fruit juice. Very wet strawberries can make parts of the cake soggy.
Check the cake early. Baking times vary depending on your tray and oven.
Let the cake cool. Cutting it while it is extremely hot can cause the soft sponge to crumble.
Keep it fresh. Because the cake contains fresh fruit, store leftovers in an airtight container in the refrigerator and enjoy them within about 2–3 days.

Delicious Variations

Strawberry and Cream Sponge Cake

Once the cake has cooled completely, spread a layer of lightly sweetened whipped cream over the top. Arrange fresh strawberries on the cream just before serving.

Strawberry and Lemon Cake

Add the finely grated zest of one lemon to the batter. The citrus aroma complements the sweetness of the strawberries beautifully.

Strawberry and Vanilla Cake

Increase the vanilla extract slightly or add a little vanilla sugar for a classic bakery-style flavor.

Strawberry Chocolate Cake

Sprinkle a small handful of chocolate chips over the batter before baking. Chocolate and strawberries create a rich and delicious combination.

Mixed Berry Tray Cake

Replace some of the strawberries with raspberries or blueberries. Use fresh, relatively dry fruit to help maintain the cake’s soft texture.

Serving Suggestions

This strawberry sponge cake is delicious served slightly warm or completely cooled.

For an everyday treat, serve it with coffee, tea, or a glass of milk. For a special dessert, add whipped cream, vanilla ice cream, or a spoonful of thick yogurt.

You can also cut the cake into small squares and arrange them on a serving platter for parties, picnics, potlucks, or family celebrations.

For a beautiful presentation, dust the cake with powdered sugar shortly before serving and add a few fresh strawberries on top.
