Take all of your dry ingredients and sift them together well.
In a small cup, combine the cream, water, yogurt, vanilla, cooled melted butter and beaten egg.
Make a well in the dry ingredients and pour the liquid ingredients into the well.
Mix until almost combined, then add in the blueberries, stir until the dry ingredients are just mixed in. My advice for the sprinkles is to add them in with each pancake, so the colors don't run all over the place.
To cook them, spread them out on the oiled griddle with the back of your spoon; the batter is thick and you will need to manually make them into circles rather then just letting a runny batter do its normal thing.
Flip the pancakes when you see a few bubbles on the top but more importantly, when you see that the edges are well cooked. This is a thick batter so the bubbles are not the most important sign of "flip times".
