There is something magical about a cake that carries both strawberries and vanilla in every soft bite. My Strawberry Vanilla Marble Sheet Cake always brings a little sunshine into my kitchen, even on the busiest days.

Hi, I’m INAYA, 38, from the beautiful island of Crete in Greece. Cooking has been part of my life since I was a child, learning from my grandmother how to make traditional Greek dishes full of love and flavor. I believe food brings people together, especially women who want to share warmth and happiness through cooking. I like to keep things simple but tasty, mixing classic recipes with a little creativity. Sometimes my kitchen gets messy, but that’s where the fun is! Whether you’re new to cooking or have some experience, I’m here to help you enjoy making delicious meals that feel like home. Cooking is about more than just food it’s about sharing stories and making memories.

When I bake this Strawberry Vanilla Marble Sheet Cake, I always remember the first time I swirled two batters together. I felt like I was painting in the kitchen. The pink strawberry mixture folding into the creamy vanilla batter creates the most beautiful marble effect. This Strawberry Vanilla Marble Sheet Cake looks elegant, but it feels cozy and comforting. I make this Strawberry Vanilla Marble Sheet Cake for birthdays, for Sunday coffee, and sometimes just because I find fresh strawberries at the market and cannot resist them.

Every time I slice into this Strawberry Vanilla Marble Sheet Cake, I see those soft pink swirls and feel proud. It tastes fresh, light, buttery, and gently sweet. It reminds me of spring mornings in Crete when strawberries fill the air with their perfume.

Why I Love Making This Recipe

I love this Strawberry Vanilla Marble Sheet Cake because it feels simple but special. I do not need layers or complicated decorating. I spread the batter into one large pan, swirl it with a knife, and let the oven do its magic.

This cake feeds many people. When my friends come over, I cut generous squares and serve them with coffee. The strawberry flavor feels bright and fruity, while the vanilla brings warmth and softness. The two flavors dance together beautifully.

I also love how forgiving this cake is. Even if my swirls are not perfect, the cake still looks artistic. Each slice becomes unique. No two pieces look the same, and I adore that.

Most of all, I love how this Strawberry Vanilla Marble Sheet Cake brings women together around my table. We talk, we laugh, we share stories. A simple cake becomes the center of connection.

Ingredients & Little Kitchen Secrets

Here is everything I use to make my Strawberry Vanilla Marble Sheet Cake.

For the Cake Batter:

3 cups all-purpose flour
1 tablespoon baking powder
½ teaspoon salt
1 cup unsalted butter, softened
2 cups granulated sugar
4 large eggs, room temperature
1 tablespoon pure vanilla extract
1 cup whole milk, room temperature
1 cup fresh strawberries, finely chopped
2 tablespoons strawberry jam
2 tablespoons all-purpose flour (for strawberries)

For the Light Strawberry Glaze (Optional but Lovely):

1 cup powdered sugar
2 tablespoons strawberry puree
1–2 teaspoons milk

My Little Secrets:

I always toss the chopped strawberries with 2 tablespoons of flour before adding them to the batter. This step keeps them from sinking to the bottom.

I use room temperature butter, eggs, and milk. When ingredients feel warm, they mix better and create a soft, even texture.

I never overmix the batter. I mix just until combined. Overmixing makes the cake dense, and I want it soft and fluffy.

How I Make It, Step by Step

I preheat my oven to 180°C (350°F). I grease and line a 9×13-inch sheet pan with parchment paper.
I whisk together the flour, baking powder, and salt in a bowl. I set it aside.
In a large bowl, I beat the softened butter and sugar together until light and fluffy. I beat for about 3–4 minutes. I watch the color turn pale and creamy.
I add the eggs one at a time, mixing well after each addition.
I stir in the vanilla extract.
I add the dry ingredients in three parts, alternating with the milk. I start and end with the flour mixture. I mix gently until just combined.
I divide the batter evenly into two bowls.
In one bowl, I fold in the chopped strawberries and strawberry jam. I stir gently to keep the batter light.
I spoon alternating dollops of vanilla batter and strawberry batter into the prepared pan.
I take a knife and gently swirl the batters together. I create soft figure-eight motions. I do not over-swirl because I want clear marble patterns.
I bake the cake for 35–40 minutes. I check with a toothpick. When it comes out clean, I remove the cake from the oven.
I let the cake cool completely in the pan.
If I make the glaze, I whisk powdered sugar with strawberry puree and a little milk until smooth. I drizzle it lightly over the cooled cake.

The smell in my kitchen at this moment feels heavenly. Sweet vanilla and warm strawberries fill the air.

How I Serve It at Home

I cut the Strawberry Vanilla Marble Sheet Cake into generous squares. Sometimes I dust it lightly with powdered sugar instead of glaze.

When I serve it for afternoon coffee, I place fresh sliced strawberries on the side. If I want to make it extra special, I add a small scoop of vanilla ice cream.

For children, I sometimes add colorful sprinkles on top of the glaze. Their eyes light up every time.

When I host gatherings, I place the whole sheet cake in the center of the table and let everyone serve themselves. I love watching people choose their slice based on the swirl pattern they like most.

Storage, Reheating & Make-Ahead Tips

I store this Strawberry Vanilla Marble Sheet Cake in an airtight container at room temperature for up to 2 days. If the weather feels warm, I refrigerate it and bring it to room temperature before serving.

I can freeze the cake without glaze. I wrap individual slices tightly in plastic wrap and store them in a freezer bag. They stay fresh for up to 2 months.

To reheat, I warm a slice in the microwave for 10–15 seconds. The strawberries become soft again, and the cake tastes freshly baked.

If I want to prepare ahead, I bake the cake one day before serving. The flavor becomes even better the next day.

100-Word Short Version

This Strawberry Vanilla Marble Sheet Cake combines soft vanilla cake with sweet strawberry swirls in one easy sheet pan dessert. I mix a fluffy vanilla batter, divide it, and blend fresh strawberries into half. I swirl the two batters together to create a beautiful marble effect. After baking until golden and tender, I drizzle a light strawberry glaze on top. The cake tastes buttery, fruity, and perfectly balanced. It works beautifully for birthdays, gatherings, or simple afternoon coffee. Each slice looks unique and feels special, yet the recipe stays simple and beginner-friendly.
