Combine 2 cups gluten free flour blend (or AP flour if not gluten free), 2 Tbsp. sugar, 4 tsp. baking powder, and a pinch of salt in a large mixing bowl. Stir to combine.
Combine 2 eggs, 1 ½ cups milk, and ¼ cup olive oil in a small mixing bowl. Whisk to completely combine.
Slowly add the wet ingredients to the dry ingredients, stirring to combine. Continue until all the wet ingredients are added to the dry ones. Stir just until combined, careful not to over-mix. Batter will be lumpy.
Heat a pan to medium-low/medium. Melt some butter in the pan. Add ¼ cup or so of the batter to the pan. The batter will spread a little as it hits the pan.
Cut 2 bananas into thin slices.
Place some of the banana slices onto the uncooked side of the pancake. Sprinkle a dusting of cinnamon on top of the bananas.
Cook the pancake for 2-3 minutes or until it starts to bubble. Flip the pancake and cook for another 2 minutes or so on the other side. The pancakes should be golden brown.
Repeat with the remaining pancake batter. *Make sure to watch the temperature of the stove top so that the pan does not get too hot. Simply reduce heat if the pancakes begin to burn.*
Top the pancakes with butter, maple syrup, additional banana slices, and other fruit if desired.
