Combine the greek yogurt and eggs in a medium sized bowl. Whisk to combine.
In a separate bowl, mix together the flour and baking soda.
Pour the yogurt mixture over the dry ingredients and stir to combine. Add in the milk and mashed banana and mix well.
Heat a large skillet on the stove to medium heat, or turn an electric griddle to 350 degrees. Melt a little butter in the skillet or on the griddle and scoop batter on top into desired sizes. (I use a heaping 1/4 cup scoop and spread them out a little.)
Once tops start to bubble, flip and cook until both sides are cooked through. Serve with maple syrup, jam, almond butter, or fresh fruit.
