Place the non-fat Greek yogurt into a medium mixing bowl.

Add the chocolate protein powder and unsweetened cocoa powder to the yogurt.

Vigorously whisk or fold the powder into the yogurt until a smooth, uniform consistency is achieved without dry clumps.

Transfer the chocolate protein base into a serving bowl.

Garnish the surface with crushed graham crackers, mini marshmallows, and chocolate chips.

Optional: Use a culinary torch to lightly toast the marshmallows for 5-10 seconds before serving.
