Place a ripe banana (they are sweeter), two eggs, cinnamon, baking powder, and vanilla into a large mixing bowl. Use an electric mixer to fully blend these ingredients. NOTE: The mixture will be thinner than if you were using a commercially prepared pancake mix with flour in it.

Spray an electric griddle (or large skillet) with non-stick baking spray (or lightly brush with oil). Heat the griddle on a medium-high heat. Once griddle is hot, carefully pour or ladle out batter into 5 pancakes (about 4" each in diameter). 

As soon as all pancakes are on grill, place blueberries onto pancakes. Once bubbles have formed on pancake surface, and they are nice and brown underneath, carefully turn the pancakes to the other side using a spatula. NOTE: Be very careful when turning. The batter is thin, and since they are studded with the weight of the blueberries, you don't want to tear the pancakes! Continue to cook the pancakes until the other side is golden brown as well, and the center of the pancake is firm.

Once done cooking, transfer pancakes to a plate. Garnish with additional banana slices and blueberries. Additional garnishes can include powdered sugar, whipped cream, regular or sugar-free pancake syrup, etc. (these calories are not included in calorie count!). Enjoy!
