Preheat oven to 350°F. Add the cupcake liners to a muffin pan.
Mix the spices together to make the chai spice and set it aside.
In a medium bowl, measure the cake flour, baking powder, baking soda, salt, and Chai spice, then set them aside.
In a measuring cup, pour the buttermilk and add the two bags of chai spice tea bags. Let it sit for 20-30 minutes. Remove the tea bags and squeeze out the excess buttermilk.
In a large bowl, beat butter, oil, and sugar with an electric mixer until light and fluffy.
Add eggs, one at a time, and mix well.
Add flour alternately with buttermilk, beating well after each addition.
Continue beating one minute. Use a cookie scoop to pour into the cupcake liners.
Bake 10-15 minutes or until a toothpick inserted in the center comes out clean.
Cool in the muffin pan, then move them to a cooling rack for 10 minutes.
