Combine flour, cake mix, baking powder, sugar and salt in a bowl and mix. Add milk, egg and vanilla extract and stir until smooth.
Preheat a skillet on medium heat. Fold desired amount of sprinkles into batter. Pour batter in 1/4 cup measurements onto skillet and let cook until bubbles form on top, about 2-3 minutes. Flip and cook for 1 minute more. Serve with vanilla glaze.
Glaze : Mix milk, extract and powdered sugar until glaze forms. You may need to add a little more sugar or water/milk to reach desired consistency. Mix into glaze and drizzle on pancakes.
