What is Kefir, and Why Use it in Baking?

What is Kefir?

Kefir is a fermented dairy product made by introducing kefir grains—tiny clusters of bacteria and yeast—into milk. The result is a tangy, creamy drink rich in probiotics, which are beneficial microorganisms that support gut health. While it shares similarities with yogurt, kefir has a thinner consistency and a more robust microbial profile, making it a nutritional powerhouse.

How Kefir Improves Cake Texture

When used in baking, kefir transforms ordinary recipes into extraordinary creations. Its natural acidity reacts with baking soda or baking powder, creating air bubbles that help the batter rise, resulting in a light and fluffy cake. Additionally, the moisture from kefir ensures your cake stays tender and doesn’t dry out, even after a day or two. The slight tangy flavor adds a sophisticated depth, balancing the sweetness of the cake beautifully.

Common Substitutes for Kefir

If you don’t have kefir on hand, there are a few alternatives that can deliver similar results:

• Buttermilk: Equally tangy and acidic, buttermilk works almost identically in baking.
• Plain Yogurt: Dilute slightly with milk or water to achieve a similar consistency to kefir.
• Non-Dairy Kefir: Made from almond, soy, or coconut milk, it’s a great option for those avoiding dairy.

Common Mistakes to Avoid When Baking with Kefir

While baking with kefir is straightforward, a few common missteps can affect the final result. Avoid these pitfalls to ensure your kefir sheet cake turns out perfectly every time.

Overmixing the Batter

• One of the most frequent mistakes is overmixing the batter. Stirring too much can activate the gluten in the flour, leading to a dense and tough cake instead of a light and fluffy texture.
• Tip: Mix the ingredients until just combined. It’s okay if there are a few small lumps in the batter—they will bake out.

Incorrect Oven Temperature

• Baking at the wrong temperature can lead to uneven baking, a burnt exterior, or an undercooked center.
• Tip: Always preheat your oven to 350°F (175°C) and use an oven thermometer to ensure accurate temperature readings. Avoid opening the oven door too often, as this can cause temperature fluctuations.

Using the Wrong Type of Kefir

• Not all kefir is suitable for baking. Flavored or sweetened kefir can alter the taste and consistency of the batter, while low-fat versions may not provide enough richness.
• Tip: Stick to plain, unsweetened kefir for the best results. If you’re using non-dairy kefir, ensure it has a similar consistency to the dairy version.

Skipping Ingredient Preparation

• Adding cold ingredients like eggs or butter directly from the fridge can cause the batter to curdle and affect the cake’s texture.
• Tip: Bring all ingredients to room temperature before mixing. This helps the batter come together smoothly and ensures even baking.

Neglecting Proper Measurement

• Inaccurate measurements, especially for dry ingredients like flour and sugar, can lead to a cake that’s too dry, too sweet, or fails to rise properly.
• Tip: Use measuring cups or a kitchen scale for precise measurements, and always level off dry ingredients with a knife.

Equipment

• 9×13 inch baking sheet

Ingredients

  

Essential Ingredients

• 2 cups 480 ml kefir
• 2 ½ cups 315 g all-purpose flour
• 1 ½ cups 300 g granulated sugar
• 2 large eggs
• ½ cup 120 ml unsalted butter, melted or vegetable oil
• 2 teaspoons vanilla extract
• 2 teaspoons baking powder
• ½ teaspoon baking soda
• ½ teaspoon salt

Optional Additions

• 1 cup 150 g fresh or dried fruits
• ½ cup 60 g chopped nuts
• 1 teaspoon ground cinnamon

Instructions

 

Step 1

• Begin by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking sheet or line it with parchment paper for easy removal.

Step 2

• In a medium-sized bowl, sift together 2 ½ cups of all-purpose flour, 2 teaspoons of baking powder, ½ teaspoon of baking soda, and ½ teaspoon of salt. Set the dry ingredients aside.

Step 3

• In a large mixing bowl, whisk together 2 cups of kefir, 1 ½ cups of granulated sugar, 2 large eggs, ½ cup of melted unsalted butter (or oil), and 2 teaspoons of vanilla extract. Make sure the mixture is smooth and well combined. If adding any spices (like cinnamon) or zest, fold them in at this stage.

Step 4

• Gradually add the sifted dry ingredients into the wet ingredients, mixing gently. Stir until the batter is just combined, being careful not to overmix. Overmixing can lead to a dense cake, so mix until the flour is incorporated, and there are no large pockets of flour remaining.

Step 5 (optional)

• If you're adding fruits or nuts, fold them into the batter now, ensuring even distribution. Lightly flour fresh fruit to prevent them from sinking to the bottom of the cake during baking.

Step 6

• Pour the batter into the prepared 9×13-inch baking pan. Use a spatula to spread the batter evenly and smooth the top. Tap the pan lightly on the counter to remove any air bubbles.

Step 7

• Place the pan in the preheated oven and bake for 25-30 minutes. Start checking at 25 minutes by inserting a toothpick into the center of the cake. If it comes out clean or with a few crumbs, the cake is done. If the toothpick comes out with wet batter, continue baking for a few more minutes.

Step 8

• Remove the cake from the oven and allow it to cool in the pan for 10-15 minutes. Once it’s slightly cooled, carefully transfer the cake to a wire rack to cool completely. This helps the cake retain its moisture and prevents it from becoming soggy.

Step 9

• Once the cake is completely cool, cut it into squares or rectangles. You can serve it plain, dust it with powdered sugar, or top it with a glaze, whipped cream, or your favorite frosting.
