If you’ve gone berry picking, this cake is a great use of the proceeds! It's a simple one to throw together and the results are so satisfying, it may become your go-to summer sweet recipe. We love the combination of red currants and blueberries (about half and half), but any mix of berries works well. The fruit piled high on top of the cake is just stunning. We like to make this dessert for friends on a Saturday night and serve the rest with coffee (if there’s any left!) on Sunday morning.
