I have made banana "ice cream" aka blended frozen bananas for several times now but the last time I experimented with adding matcha powder and it was the best decision I've ever made. The result was just surprisingly amazing.
For one serving you need 2 large bananas, peeled, cut into chunks and then frozen in a freezer, 1-2 teaspoons matcha powder. Blend everything and optionally add some honey but not much because bananas are alrady rather sweet and creamy. Serve with berries or/with nuts.
Almost equally good with blueberries..
