Prep Work
Before we dive into mixing our ingredients, preparing our tools and environment is crucial for a flawless Kefir Sheet Cake experience. Proper prep ensures even baking and that our cake comes out perfectly moist and tender.
Preparing the Baking Pan
To prevent sticking and guarantee easy removal of our kefir sheet cake:
- Grease the 9×13-inch sheet pan thoroughly with unsalted butter or non-stick spray.
- Line the bottom with parchment paper, leaving a slight overhang for easy lifting.
- Lightly flour the parchment paper after greasing to improve the release.
- Alternatively, use a silicone baking mat if available for a reusable, no-stick surface.
This preparation ensures a clean release without compromising the cake’s texture or shape.
Preheating the Oven
For consistent results:
| Step | Temperature | Time | Notes |
|---|---|---|---|
| Preheat oven | 350°F (175°C) | 15 minutes | Allow full preheating before baking |
| Position rack | Middle | N/A | Promotes even heat circulation |
- Set your oven to 350°F (175°C) and let it fully preheat for at least 15 minutes.
- Place the oven rack in the center to allow even baking and prevent over-browning on the bottom or edges.
Preheating the oven properly is a key step we never skip, as it helps the kefir sheet cake rise evenly and bake uniformly.
Instructions
Follow these step-by-step instructions to create our moist and flavorful Kefir Sheet Cake. By carefully combining the ingredients and baking with precision, we ensure the perfect tender crumb that this cake is known for.
Making the Kefir Cake Batter
- Combine Dry Ingredients: In a large mixing bowl, sift together 2 ½ cups of all-purpose flour, 1 ½ teaspoons baking powder, 1 teaspoon baking soda, and ½ teaspoon salt. Sifting aerates the flour, helping create a light and fluffy texture.
- Mix Wet Ingredients: In a separate bowl, whisk 2 cups of plain kefir, 1 ¾ cups granulated sugar, ½ cup melted unsalted butter, 3 large eggs, and 2 teaspoons vanilla extract until the mixture is smooth and homogeneous.
- Incorporate Wet and Dry Mixtures: Gradually add the wet ingredients into the dry. Using a rubber spatula, fold gently but thoroughly. Avoid overmixing to keep the cake tender.
- Optional Add-ins: At this stage, gently fold in any optional ingredients like ½ cup chopped nuts or fresh berries, adding texture and flavor without weighing the batter down.
Baking the Cake
- Prepare the Pan: Ensure your 9×13-inch sheet pan is greased and lined with parchment paper, dusted lightly with flour to help with easy release after baking.
- Preheat Oven: Set the oven to 350°F (175°C) and allow it to preheat for at least 15 minutes. Place the oven rack in the center for even heat distribution.
- Pour Batter: Pour the batter evenly into the prepared pan, smoothing the top gently with the spatula to avoid air bubbles.
- Bake: Place the pan in the oven and bake for 35 to 40 minutes. Maintain consistent oven temperature throughout for even baking.
Checking for Doneness
To ensure our Kefir Sheet Cake comes out perfectly moist and tender, use the following methods:
| Method | Description |
|---|---|
| Toothpick Test | Insert a toothpick in the center. It should emerge with a few moist crumbs but no raw batter. |
| Touch Test | Gently press the surface; it should spring back mildly without leaving an indentation. |
| Visual Cues | The edges will pull slightly away from the pan, and the top will have a light golden color. |
If the cake isn’t fully baked, return it to the oven and check every 3-4 minutes to avoid overbaking.
By carefully following these precise steps, we guarantee a luscious, probiotic-rich Kefir Sheet Cake that delights both the palate and the eyes.
Frosting or Glaze (Optional)
Adding a frosting or glaze to our Kefir Sheet Cake is an excellent way to enhance its flavor and presentation. Whether you prefer a rich cream cheese frosting or a simple citrus glaze, these finishing touches elevate the cake’s moist crumb and tangy notes.
Ingredients for Frosting or Glaze
Below are the two popular options for finishing our Kefir Sheet Cake:
| Type | Ingredients |
|---|---|
| Cream Cheese Frosting | 8 oz cream cheese (softened), 1/2 cup unsalted butter (softened), 3 cups powdered sugar, 1 tsp vanilla extract |
| Lemon Glaze | 1 cup powdered sugar, 2 tbsp freshly squeezed lemon juice, 1 tsp lemon zest (optional), 1-2 tbsp water or milk |
Preparing the Frosting or Glaze
Cream Cheese Frosting:
- In a large bowl, beat the softened cream cheese and butter together until smooth and creamy using an electric mixer.
- Gradually add the powdered sugar while mixing on low speed to avoid a sugar cloud.
- Stir in the vanilla extract for a subtle vanilla undertone.
- Continue mixing on medium speed until the frosting is light and fluffy, about 2-3 minutes.
Lemon Glaze:
- In a small bowl, whisk together the powdered sugar and freshly squeezed lemon juice until smooth.
- Add lemon zest for extra brightness if desired.
- Adjust consistency with water or milk—add slowly a teaspoon at a time—until the glaze is pourable but not too thin.
Applying the Frosting or Glaze
- For Cream Cheese Frosting:
Allow the Kefir Sheet Cake to cool completely on a wire rack. Using an offset spatula or butter knife, spread the frosting evenly over the top. Smooth the surface or create peaks for texture. Chill the frosted cake for 30 minutes to set before slicing.
- For Lemon Glaze:
Once the cake has cooled to room temperature, drizzle the glaze generously over the cake using a spoon or a small whisk. Let it drip down the sides naturally. Allow the glaze to set for 15-20 minutes before serving.
Adding either of these optional coatings enhances the cake’s moist texture and adds an enticing flavor contrast that complements the tangy kefir base beautifully.
