Preheat oven to 400°F.
Whisk together DONA masala chai, milk, eggs, sugar, and salt in a bowl. Pour into a sheet pan, then add bread and soak, until bread has absorbed liquid, about 10 minutes.
Heat 1 ½ tablespoon butter in a 12-inch nonstick skillet over medium-high heat.
Transfer bread slices to skillet and cook, turning once, until slightly puffed and golden brown. Place on a large baking sheet. Repeat this process until each of the bread slices has been seared, adding 1 ½ tablespoon butter between batches.
Finish in the oven. Toast should be golden and firm to the touch, about 8 minutes. Serve with fresh figs and maple syrup.
