To the dry ingredients, add 2 eggs, 1/2 cup milk, 1/4 cup vegetable oil, 2 tsp vanilla and mix well, scraping down the sides of the bowl. Add the 1/2 cup cacao tea (being careful not to splash!) Combine with a mixer or a whisk. Once combined, use an ice cream scooper to scoop batter into each liner cup (fill each cup only 3/4 full).
