Anyone ever make a Flatbread on a pan from Jamie Oliver?

So Jamie Oliver has a quick and easy flatbread recipe I can’t seem to get right. It’s… 1/4 cup bread flour 1/4 cup warm water 1 tablespoon yogurt 1 teaspoon baking powder. Whisk until it’s a thick batter/almost a dough. Put it on a heated, oiled non stick pan. Spread it around. Flip. Seems easy but I keep getting a doughy mess at first on the pan that I can use a spatula to press into a thick crispy pancake thing that is edible but has no shape. Anyone have a better way to do this concept? I would like to quickly make a flatbread so I can quickly make a toasty/bootleg panini. Thanks. submitted by /u/Itchy-Picture-4282
