Start by thawing your frozen berries. You can do this by leaving them out at room temperature for about 30 minutes or quickly warming them in the microwave for a few seconds. Make sure to reserve the liquid that forms as they thaw.
In a mixing bowl, combine the thawed berries along with their liquid, heaping tablespoon of cocoa powder, ground flax seed, nut butter, and extra-virgin olive oil. Use a fork or whisk to blend everything until smooth.
Slice the ripe banana into thin pieces. Fold the banana slices into the chocolate mixture, ensuring they are well dispersed throughout.
In a separate bowl, spoon out the Greek yogurt. Gently swirl in the chocolate mixture, creating a marbled effect.
Transfer the chocolate yogurt mixture into your serving bowl. Sprinkle the diced or chopped nuts over the top for added crunch and texture.
