Pre-heat oven to 180c (350 F) and butter a ~8 inch square / round baking dish. (I lined an 8 inch round cake tin which also worked perfectly.)
Add the strawberries to a bowl with around 2 tbs of the sugar and mash them with the back of a spoon or fork to release all of their delicious juices. Try to resist just eating this as it is...
Mix together the rest of the sugar, melted butter, milk and salt in a bowl. Sift in the flour and baking powder and whisk well until you have a smooth batter.
Pour the batter into the buttered dish / tin and spread evenly to the edges.
Spoon out the mashed strawberries and all of those juices onto the top of the batter - it might look like a lot of juice here but that's totally fine!
Place in the oven and bake for 25 minutes, until a toothpick inserted into the centre comes out clean. If it's not done at 25 minutes, just pop it back in for another 2 minutes and keep checking until it's done.
Remove and allow to cool on a cooling rack. Hold-off for a good 5-10 minutes minutes to avoid burning your mouth on the super-hot jammy bits. Serve warm with lactose-free yoghurt or low FODMAP ice cream... or whatever you fancy!
