Ingredients
For the Cake Batter:

- 1¼ cups (250g) granulated sugar
- 2 cups (480ml) kefir or buttermilk
- 1 large egg
- 3 tablespoons unsweetened Dutch-process cocoa powder
- 1 teaspoon baking soda

For the Chocolate Glaze:
- 1 cup (175g) dark or semi-sweet chocolate chips
- ⅓ cup (80ml) heavy cream
- 3 tablespoons unsweetened shredded coconut (for sprinkling)
Instructions
Prepare the Baking Sheet:
- Grease a 9×13-inch (23×33 cm) baking sheet with a tablespoon of oil.
- Dust it lightly with breadcrumbs or flour to prevent sticking.
Preheat the Oven:
- Set the oven to 340°F (170°C) and allow it to preheat.
Mix the Batter:
- In a large mixing bowl, combine 2 cups of kefir and ½ cup of sunflower oil.
- Add 1 large egg, 1¼ cups of granulated sugar, and 3 tablespoons of unsweetened cocoa powder.
- In a separate bowl, whisk together 2 cups of all-purpose flour and 1 teaspoon of baking soda.
- Gradually add the dry ingredients to the wet mixture, stirring continuously until a smooth, semi-liquid batter forms.

Bake the Cake:
- Pour the batter onto the prepared baking sheet, spreading it evenly with a spatula.

- Place the baking sheet in the preheated oven and bake for approximately 20 minutes.

- To check for doneness, insert a wooden skewer into the center of the cake; if it comes out clean, the cake is ready. If not, bake for an additional 3-5 minutes and test again.
Cool the Cake:
- Once baked, remove the cake from the oven and allow it to cool completely in the pan.
Prepare the Chocolate Glaze:
- Set up a double boiler by placing a smaller pot over a larger one with simmering water.
- In the smaller pot, melt 1 cup of chocolate chips, stirring occasionally.
- Once melted, add ⅓ cup of heavy cream and stir until the mixture is smooth and glossy.
Glaze the Cake:
- Pour the chocolate glaze over the cooled cake, spreading it evenly to cover the entire surface.
Add the Finishing Touch:
- Allow the glaze to set for a few minutes, then sprinkle 3 tablespoons of shredded coconut evenly over the top.

Serve:
