Place 2 pounds 8oz brownie mix, 4oz cake flour, 0.17oz or 1tsp baking powder, 12oz whole eggs, 7.7oz vegetable oil, 4oz water in the bowl of a stand mixer fitted with the paddle attachment. Mix for 2 min on low speed, scraping down the bowl halfway through mixing time
Spray donut baking pan with non-stick spray. Deposit 1.5 oz into each cavity. Bake at 350F roughly 13 minutes until batter springs back lightly when touched. Let cool for 5 min, then turn out and let cool completely.
Once donuts have cooled, warm donut icing and dip tops into icing, sprinkle with bacon bits and let set up.
