Start by breaking the dark chocolate into small pieces and placing them in a microwave-safe dish. Heat in the microwave for about 30 seconds on high power. Stir the chocolate after this initial heating until it is smooth and completely melted.

In a high-speed blender, combine the ripe bananas, frozen strawberries, and the melted dark chocolate. Pour in the almond milk, adjusting the amount based on your desired thickness, and toss in a handful of ice.

Secure the blender lid tightly and blend the mixture on high speed for about 30 to 60 seconds until it reaches a smooth, thick consistency.

Once blended, taste your smoothie. If desired, add more melted chocolate or another banana, and blend for a few more seconds.

Pour the smoothie into chilled glasses. Garnish with fresh fruit or a sprig of mint and serve immediately.
