Combine coconut flour and protein powder in a bowl. Whisk in eggs. Add milk, 1/4 cup at a time, mixing thoroughly, until batter is not too thick or too runny. Sprinkle batter with coconut flakes and chocolate chips; mix well.
Grease a skillet with olive oil spray and place over medium-high heat. Fry banana slices until golden brown, about 3 minutes. Flip banana slices, add a drop of honey onto each one, and cook until caramelized, about 3 minutes. Transfer banana slices to a plate, keeping 3 in the skillet.
Drop a large spoonful of batter over the banana slices in the same skillet. Cook until bubbles form and the edges are dry, 3 to 4 minutes. Flip and cook until browned on the other side, 2 to 3 minutes. Repeat with remaining banana slices and batter.
