Gather the ingredients for your strawberry spoon cake.
Grease your baking dish with butter and preheat the oven to 350°F.
Smash the strawberries with the back of a fork to release their juices. Add 1/3 cup brown sugar and stir until dissolved. Set aside.
In a separate bowl, whisk together the flour, melted butter, milk, salt, and the remaining brown sugar. Add the baking powder and mix until smooth.
Pour the batter into the prepared baking dish, then use a spatula to even out the surface.
Top the batter with the strawberry mixture and bake for 20 minutes.
Let cool for 5 minutes, then serve with a scoop of vanilla ice cream. Enjoy!
