Instructions

1. Preheat the oven to 375°F (190°C). Lightly grease a pan with butter. Mix the flour and baking powder together, then sift. Add the salt and mix well. Set aside.
2. Use an electronic hand mixer or stand mixer to beat the butter and sugar until well combined and pale yellow in color. Add the first egg and beat well after each egg addition until creamy. Scrape down the sides, then add the vanilla extract. Fold the flour into the mixture and mix well. Add the milk.
3. Divide the batter into two portions. Stir the cocoa powder into one portion and mix well. Transfer the plain batter into the greased baking pan and shake it lightly to distribute it evenly.
4. Pour the cocoa batter into the middle of the baking pan and lightly swirl it with a butter knife. I usually make an "S" shape with the knife a few times. Be careful not to overmix.
5. Bake until golden brown and cooked through, about 40 minutes. If the top browns too quickly before the cake is set, cover it with aluminum foil at the 20-minute mark to prevent it from becoming too brown and crusty.
6. Insert a cake tester into the center of the cake to check for doneness. If the middle is still wet, bake for a little longer. Remove the cake from the oven and let it cool on a wire rack for 5 minutes. Then, remove it from the pan, slice, and serve immediately.
