Step 8-:. Add ½ of the flour mixture to the batter and mix till combined. Also, add the milk mixture to the batter and mix till combined. At last, add the remaining flour mixture and mix until it is smooth. Scrape down the edges of the bowl to confirm everything is being combined.

Step 9-: Divide the batter equally between the already prepared and ready cake pans. Bake for 22-24 minutes, or until a pick inserted within the middle comes out with many crumbs onto it.

Step 10-: Take out the cakes from the oven and let it cool down for 3-4 minutes, then remove from the pans to a cooling rack to finish cooling.
