To Make the Pancakes:
Preheat a griddle pan or large frying pan over medium low heat.
In a medium bowl, whisk together the flour, sugar, salt, baking powder, and baking soda.
In a separate medium bowl, whisk together the yogurt, milk, egg, oil, and vanilla until well combined.
Add the wet ingredients to the dry ingredients and mix until just combined. Do not over mix. Let the batter sit for 10 minutes.
Divide the batter into two bowls, and gently mix half the sprinkles into the first bowl.
Lightly and carefully grease your pan.
Spoon the batter into four places on the griddle pan. Cook for 2 - 3 minutes, until golden brown. Flip and cook for 1 - 2 minutes on the other side. Remove pancakes to a wire rack.
Stir the rest of the sprinkles into the remaining batter, and repeat cooking process.
To Make the Sauce:
In a small bowl, stir together the yogurt, vanilla, honey, and milk. Add more milk until desired consistency is reached.
Serve pancakes topped with yogurt sauce and extra sprinkles.
