Notes

Slice the butter thin and spread it all over as much as possible. The cake will bake better if the butter melts all over.
The amount of blueberries depends on how many you would like. We love them, so we add the full six cups. But four is plenty, as well.
You can store any leftovers in an airtight container or cover with some plastic wrap and keep refrigerated.
You can add a scoop of ice cream right on top for some extra sweetness.
Every once in a while, the cake mix doesn't want to bake, so you need to make sure you slice the butter thin and get it all over the cake.
