Ingredients You’ll Need
Before we dive into the baking process, let’s go over everything you’ll need to create this delicious cake. The beauty of this recipe is that it relies on simple, quality ingredients that work together to create something extraordinary.
- 2 cups all-purpose flour
- 1 cup granulated sugar
- 1/2 cup unsalted butter, softened
- 2 large eggs, room temperature
- 1 cup plain kefir
- 1 teaspoon vanilla extract
- 1/2 teaspoon baking soda
- 1 teaspoon baking powder
- 1/4 teaspoon salt
- Optional: 1 tablespoon lemon zest for brightness

Step-by-Step Instructions For Kefir sheet cake
Now that we’ve gathered all our ingredients, it’s time to bring this cake to life. I’ll walk you through each step to ensure your kefir sheet cake turns out perfectly every time.
Preparation
Let’s start by getting everything ready to make the baking process smooth and enjoyable.
- Preheat your oven to 350°F (175°C) and position a rack in the center.
- Grease and flour a 9×13 inch baking pan, or line with parchment paper for easy removal.
- Measure all ingredients and allow refrigerated items like eggs, butter, and kefir to come to room temperature.
- In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
Baking Method
Now comes the fun part! Let’s transform these simple ingredients into an amazing cake.
- Start by creaming butter and sugar in a large bowl using an electric mixer until light and fluffy, about 3 minutes.
- Add eggs one at a time, beating well after each addition until fully incorporated.
- Mix in vanilla extract and lemon zest (if using) until combined.
- Gradually add the flour mixture to the butter mixture in three parts, alternating with the kefir (begin and end with flour).
- Pour the batter into your prepared pan, spreading evenly to the corners.
How to Know When It’s Done
The key to perfecting this kefir sheet cake is knowing exactly when it’s ready. Look for these important signs:
The color should be a golden brown around the edges rather than pale. The texture should spring back when lightly touched in the center but not be overly firm. A toothpick inserted into the center should come out clean or with a few moist crumbs.
Finishing Touches
To complete your cake and take it from good to absolutely amazing:
- Remove from oven and place on a cooling rack for 15 minutes before removing from the pan.
- Allow to cool completely before adding your favorite frosting or glaze.
- Consider a light dusting of powdered sugar or a simple cream cheese frosting for an extra touch of decadence.
Tips for Perfect Results
Want to ensure your kefir sheet cake turns out perfectly every time? These professional tips will help you avoid common mistakes:
- Room temperature ingredients are crucial – cold eggs or kefir can cause the batter to curdle and affect the final texture.
- Don’t overmix the batter after adding the flour – this develops gluten and can make your cake tough rather than tender.
- Make sure to measure flour correctly by spooning it into measuring cups and leveling off, rather than scooping directly from the bag.
Variations to Try
Once you’ve mastered the basic recipe, why not experiment with these delicious variations?
- Citrus version: Add orange zest and a simple orange glaze for a bright, refreshing flavor profile
- Berry delight: Fold 1 cup of fresh berries into the batter for bursts of fruit in every bite
