Instructions
Prepare the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and chai spices (cinnamon, cardamom, ginger, nutmeg, cloves, and allspice).
Set aside.
Cream the Wet Ingredients
In a large mixing bowl, beat the softened butter and brown sugar with an electric mixer until light and fluffy (about 3 minutes).
Add eggs one at a time, beating well after each addition.
Mix in the vanilla extract.
Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet mixture in three parts, alternating with the milk: Start and finish with the dry ingredients to avoid overmixing. If using optional add-ins, gently fold them in at this stage.
Bake
Preheat the oven to 350°F (175°C).
Grease and flour a 9-inch round or square cake pan (or line with parchment paper).
Pour the batter into the prepared pan and spread evenly.
Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
Let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
