Strawberry Sweet Roll Mug Cake

all purpose flour (strong white flour in the UK) (, plus more for dusting your surface. I like to use unbleached flour )

baking powder

sugar (, lighter coloured varieties are best)

salt

enough water (, to bring the dough together into a non sticky dough. It will vary depending on your flour brand and humidity. I used 4 tablespoons)

medium fresh strawberries (, chopped into small pieces. (Frozen strawberries work too - not defrosted just chopped and rolled up in the dough while still frozen. The flavour will be better with fresh strawberries though). )

natural powdered sugar

few drops water, plant-based milk or lemon juice (, no more than a teaspoon)

a tiny dab of oil for greasing the mug (, I used coconut oil (OPTIONAL _ omit to make oil-free))
