Hello! I was wondering what is making my cupcakes flat looking. Could it be too much liquid? The recipe is one I use for cakes so I thought it would transfer to cupcakes. If anyone has any suggestions let me know!

Recipe:
1 ¾ c. ap flour
2 c. sugar
¾ c. cocoa powder
2 tsp. baking soda
1 tsp. baking powder
1 tsp kosher
1 c. buttermilk
½ c. oil
2 eggs
1 tsp. vanilla 
1 c. hot water
1 tsp espresso powder
