01 - Preheat the oven to 350°F. Grease and line two 8-inch round cake pans with parchment paper.
02 - Heat the milk until just simmering, then steep the chai tea bags in the milk for 10 minutes. Remove and discard the bags, squeezing out excess liquid. Allow the infused milk to cool.
03 - In a large bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, ginger, cardamom, cloves, and nutmeg until evenly mixed.
04 - In a separate bowl, beat granulated sugar, brown sugar, and vegetable oil until well combined. Add eggs one at a time, beating thoroughly after each addition, then stir in vanilla extract.
05 - Alternately add the dry ingredients and chai-infused milk to the wet mixture, starting and ending with the dry ingredients. Mix gently until just combined to avoid overmixing.
06 - Divide the batter evenly between the prepared pans. Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean.
07 - Let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
08 - Beat cream cheese and butter until smooth and creamy. Gradually add powdered sugar, vanilla extract, and salt, beating until light and fluffy.
09 - Place one cake layer on a serving plate. Spread half of the cream cheese frosting evenly over the top. Position the second layer on top and cover with the remaining frosting.
10 - Optionally, sprinkle cinnamon or chai-spiced tea leaves atop the frosted cake for decoration.
