METHOD

preparation
Grease and line two 22 cm (9-inch) cake pans with parchment paper. You can also use one pan and bake the layers in two batches. I don’t recommend baking a single thicker sponge, as it tends to crumble. Place the oven rack in the middle position and preheat the oven to 180°C (350°F).

cake
In a bowl, whisk together the flour and baking powder. In a separate large bowl, beat the eggs, sugar, brown sugar, and vanilla sugar until light and fluffy, about 5 minutes. Add the oil and mix until well combined, about 1–2 minutes. Alternately add the flour mixture and kefir while mixing gently. Do not overmix—this step should take no longer than 1 minute. Finally, using a spatula, gently fold in the walnuts, grated carrots, and spices with light, circular motions.
-
bake the cake
Divide the batter evenly between the prepared cake pans and place them in the preheated oven on the middle rack. Bake for 30–35 minutes at 180°C (350°F). Once baked, transfer the cakes onto a wire rack, placing them upside down so the top faces down. Let them cool completely to room temperature.
-
cream cheese filling
Prepare the frosting. Beat the softened butter and vanilla sugar until light and fluffy, about 3–4 minutes. Add half of the powdered sugar and beat for another 2 minutes. Then add the remaining powdered sugar and the cream cheese. Mix briefly until you get a smooth, creamy frosting. Place it in the refrigerator for 20–30 minutes to firm up slightly.
-
decorate
Generously spread the cream over the carrot sponge to create a layer about 3 cm (1.2 inches) thick. Place the second cake layer on top, then frost the entire cake with the remaining cream and decorate as desired. Finish by coating the sides of the cake with chopped walnuts.
-
serve
Chill the cake in the refrigerator for 1 hour, then slice and serve. Store any leftovers in the refrigerator for up to 3 days.
