Let me tell you this is one of the best plum cakes ever. It has almonds, honey and that awesome balance between sweet and sour from the fresh plums.
Preheat oven to 350ºF / 180ºC.
Line or butter an 8-inch round with removable bottom or square cake pan lined with parchment paper.
Melt butter in a large bowl.
Add sugar and honey. Mix well with a hand beater.
Add egg, extracts, salt and baking powder. Mix well until creamy.
Add flours in 2 or 3 parts, mixing well, but not too much.
Pour into the prepared pan and arrange plum pieces on top.
Bake for about 30-40 minutes, until a tester comes almost dry (this is a very moist cake so it will not be completely dry).
Let cool completely on wire rack.
Sprinkle powdered sugar on top (not too much) and serve.
