Chocolate frozen dessert with almonds

Four ingredients, simple, creamy and delicious.

3 frozen bananas (about 2 1/2 cups)
2T cocoa (I use a Dutch-processed, fairly traded brand)

1/4 cup soft dates, pitted and finely chopped.
1t sliced almonds, crushed

Optional: 1t powdered maca

Puree the bananas, cocoa and dates until smooth, spoon out, and garnish with almonds.
