Add a layer of mixed berries. I used raspberries, blueberries, and strawberries.
Repeat with another set of layers. I add a ton more berries on the top layer. I wanted this cake to look rustic and homemade. See how it started to crack? It still tasted amazing and no one even noticed the crack. If they did, they were polite enough to not mention it. I very well may have cried if they did.
