In a deep frying pan, add 2 to 2 1/2-inches of oil and heat to 350 to 375 degrees F or until a drop of batter immediately rises to the surface.
While oil is heating, sift together in bowl the flour, baking powder, and salt. Beat eggs in a separate bowl and add to dry ingredients. Add milk and vanilla to batter and mix until all ingredients are incorporated and it has a pancake batter-like consistency. Add additional milk a little at a time if needed. Let batter rest for 10 minutes to let the baking powder to become active and bubble.
Next, cut bananas into 1-inch size pieces on an angle and toss in a bowl with lemon juice. Using two forks, coat banana pieces with the batter and drop one at a time into the hot oil. Let cook until both sides are golden brown, about 3 to 4 minutes for each side. Turn bananas with forks as they brown. Remove and drain on paper towels, then place in oven on a lined baking pan to keep warm. Repeat steps if doing a larger batch. Pour syrup over bananas and serve as a dessert or side dish.
