How to Make Kefir Sheet Cake

Step-by-Step Instructions

  1. Set Up the Oven and Pan: Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch sheet pan and sprinkle it with flour, or use parchment paper to line the bottom for easier removal.
  2. Combine Dry Ingredients: In a medium mixing bowl, whisk together the flour, baking powder, and baking soda until they are evenly distributed.
  3. Cream Butter and Sugar Together: In a large bowl, beat the butter (or oil) and sugar until the mixture becomes fluffy and smooth. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract to blend.
  4. Mix in Kefir Gradually: Alternate adding the dry ingredients and kefir into the wet mixture, starting and ending with the dry ingredients. Mix only until everything is combined to avoid overmixing.
  5. Bake the Cake Until Done: Pour the batter evenly into the pan, smoothing out the top. Place it in the center of the oven and bake for 25 to 30 minutes, or until a toothpick inserted into the middle comes out clean or with a few moist crumbs.
  6. Cool and Finish: Allow the cake to cool in the pan for about 10 minutes before transferring it to a wire rack. Let it cool completely before adding any toppings or frosting.
