Essential Ingredients for Kefir Sheet Cake

Making the best kefir sheet cake begins with the right ingredients. Each ingredient is critical to producing the right texture and taste.

Key Ingredients

• Kefir: Adds tanginess, moisture, and a probiotic boost. Use plain, unsweetened kefir for balanced sweetness.
• All-Purpose Flour: Provides structure while keeping the cake tender. Sifted flour prevents lumps.
• Leavening Agents: Baking soda reacts with kefir’s acidity for fluffiness while baking powder guarantees an even rise.
• Sweeteners: Granulated sugar balances tanginess and brown sugar offers a caramel-like richness.
• Fat: Butter or oil adds moisture and richness. Butter gives a creamy taste, while oil guarantees extra softness.
• Eggs: Bind ingredients together and add structure. Use room-temperature eggs for a smoother batter.
• Flavor Enhancers: Vanilla extract, citrus zest, or spices like cinnamon can enrich the cake’s flavor.

Optional Add-ins

• Chocolate chips, chopped nuts, or fresh fruits for variety.
• A cream cheese or chocolate glaze for a polished finish.
