Instructions of kefir sheet cake
Preheat the Oven
- Preheat your oven to 350°F (180°C). 🔥
- Grease a 9×13-inch baking pan and line it with parchment paper. This makes removing the cake hassle-free and prevents sticking.
“Pro Tip: If you don’t have parchment paper, dust the greased pan lightly with flour for an easy-release alternative.”
Mix the Dry Ingredients
- In a medium bowl, whisk together:
- 2 cups all-purpose flour
- 1 1/2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 3/4 cup natural sweetener (erythritol or monk fruit).
- Ensure everything is evenly mixed to prevent lumps in the batter.
Combine Wet Ingredients
- In a large mixing bowl, whisk 2 large eggs until frothy.
- Add the following to the eggs and mix thoroughly:
- 1 cup plain kefir
- 1/2 cup vegetable oil (or melted coconut oil for a richer taste)
- 1 teaspoon vanilla extract.
- Stir until the wet mixture is smooth and uniform.
Combine Wet and Dry Mixtures
- Gradually fold the dry mixture into the wet mixture in three parts.
- Use a spatula or whisk and mix gently until just combined. Overmixing can make the cake dense instead of fluffy.
“If the batter feels too thick, add 1–2 tablespoons of kefir to adjust the consistency.”
Bake the Cake
- Pour the batter evenly into the prepared pan and smooth the top with a spatula.
- Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.
- Let the cake cool completely in the pan before applying the glaze or slicing.
“Pro Tip: Rotate the pan halfway through the baking time to ensure even cooking.”
Prepare the Glaze (Optional)
- In a small bowl, whisk the following until smooth:
- 1 cup powdered erythritol or monk fruit sweetener
- 2 tablespoons kefir
- 1/2 teaspoon vanilla extract.
- Once the cake has cooled, drizzle the glaze on top for a polished finish.
“For a decorative touch, sprinkle the glazed cake with chopped nuts, shredded coconut, or fresh berries before serving!”
Common Problems and Solutions of kefir sheet cake
Why is My Cake Dense?
A dense cake can result from overmixing the batter, which activates too much gluten. To prevent this, mix the ingredients gently and stop as soon as everything is combined. Using room-temperature ingredients can also help ensure a smoother batter.
How Do I Avoid Overbaking?
Overbaking leads to a dry cake. Check for doneness 5 minutes before the suggested baking time ends. Insert a toothpick into the center; if it comes out clean or with a few moist crumbs, the cake is ready. Remember, sugar-free cakes can dry out faster, so keep an eye on it.
Can I Replace Kefir?
Yes, kefir can be substituted with buttermilk, plain yogurt, or a mix of milk and lemon juice. However, kefir adds a unique tangy flavor and moisture that makes this cake special, so use it whenever possible.
“Pro Tip: Always use fresh baking powder and baking soda to ensure your cake rises properly and stays fluffy!”
