Preheat the oven to 340°F (170°C).
Fill a kettle with water and bring it to a boil. In a bowl, combine the honey and hot water, stir, and add 2 tea bags. Let them steep until the tea releases its color, then set aside.
In a large bowl, whisk together the eggs, brown sugar, and white sugar. Add the oil and stir until combined.
Add the cinnamon, cocoa powder, flour, baking soda, and the honey-tea mixture. Whisk thoroughly until the batter is smooth.
Pour the batter into a greased 24 cm (9.5-inch) baking pan and bake for about 40 minutes, or until a toothpick comes out with moist crumbs.
Remove from the oven and let it cool. Dust with powdered sugar and enjoy!
