1. Preheat the oven to 350 degrees F (175 degrees C). Drop butter into an 8 inch square and let melt in the preheating oven.
2. Remove the pan from the oven and tilt to coat the bottom evenly with butter. Sprinkle brown sugar and almond flour on top. Arrange plum slices over the mixture.
3. Beat softened butter and sugar together until light and creamy. Mix in egg and vanilla extract until fluffy.
4. Sift flour, baking powder, salt, and cinnamon together in a separate bowl. Add to the butter mixture alternately with the milk, folding just until dry spots disappear. Pour batter evenly over the plums; tap pan onto the counter to expel excess air bubbles.
