Blueberry Pancake Cupcakes with Maple Syrup Buttercream

I found this recipe via pinterest. It sounded heavenly, and it definitely delivered!
I changed some ingredients around based on what I had / trying to be healthier and cheaper.
This made 32 cupcakes. I also had to adjust the cooking time, but that could be my finicky oven.

ingredients
for the cupcakes
2 sticks butter, softened
1.5C sugar
3 eggs, room temperature
2 egg whites, room temperature
3 1/3C all-purpose flour
1 tsp baking soda
1/2 tsp baking powder
1 tsp salt
1 tsp cinnamon
1/2 tsp nutmeg
1C plain greek yogurt
1/3C skim milk
1 tbsp vanilla
1.5C frozen blueberries (they hold up better in batter)

for buttercream
1 stick butter, softened
1 8oz package of cream cheese, softened
1/3C maple syrup (less if you're not using the pure, real thing...otherwise it will be REALLY sweet)
5.5C powdered sugar

for decoration
3 fresh blueberries per cupcake
cinnamon sugar

directions

1. Preheat the oven to 360 degrees.
2. Line pans with cupcake liners (or spray the pans if you don't want to use liners).
3. In large bowl (I used my KitchenAid) beat butter and sugar until fluffy.
4. On low speed, add eggs and egg whites one at a time until well combined.
5. Combine dry ingredients in a separate bowl.
6. Add dry ingredients to the butter mixture in thirds, alternating with the wet (greek yogurt, vanilla, coconut water) until fully combined.
7. Fold in frozen blueberries.
8. Fill cupcake liners 3/4 full.
9. Bake for ~28 minutes, or until a toothpick comes out clean. (The recipe recommended 18 minutes but mine were still batter at that point)
10. In large bowl (I used my KitchenAid), beat butter and cream cheese until fluffy.
11. Add maple syrup and powdered sugar little by little (unless you want a powdered sugar cloud then add it all at once!).
12. If the frosting is too thick, add a little bit of milk until the texture is more to your liking.
13. Pipe buttercream onto  cooled cupcakes.
14. Sprinkle cinnamon sugar on top of buttercream.
15. Top wtih 3 blueberries.
16. Enjoy!
