Combine flour, sugar, salt, and baking powder into a bowl and mix well.

In a separate bowl, mix the egg, milk, vanilla, and melted butter together. Be careful not to use hot, melted butter, as that may end up cooking your eggs!

Pour the wet ingredient mixture into the dry ingredients and stir till mostly incorporated. The batter should be thick and a little lumpy, but without any visible streaks of flour. If it is too thick to work with, add a little milk. Set the batter aside for 5-10 minutes.

Heat a heavy-bottomed, non-stick pan over a low-medium heat and coat it with oil. Use a 1/4 cup measure to scoop and drop the batter into the pan with jam after that cover the jam with some pancake mix so that when flipped it when burnt.

Cook until the first side is golden brown, or until the top surface forms bubbles. Flip and repeat on the other side. Adjust heat accordingly. Serve while still hot with some butter on top and condensed milk/chocolate syrup/maple syrup.
