Line an edged baking sheet with foil. Lay your bacon strips on the sheet, then place in the oven. Heat the over to 375 and cook for about 15 minutes. When done, transfer to paper towel-lined plate to drain excess grease.
Heat 2-3 inches of oil in a deep fryer or skillet to 350 degrees.
In a bowl, mix together flour, Doritos, baking powder, and salt. Mix thoroughly so that the baking powder is evenly distributed. Slowly add in 1 cup of beer. Stir until your batter is smooth.
Cut the bacon strips in half, or smaller bites if you’d like, then coat each piece in the batter. Carefully drop it in the hot oil. Cook for about 2-4 minutes, turning over halfway through. Place cooked pieces onto a cooling rack or another paper towel-lined plate.
