Step by Step Process: 1. In a blender, combine the chilled brewed coffee, unsweetened almond milk, sugar, eggs, vanilla protein powder, cocoa powder, and cinnamon. 2. Blend on high speed until all the ingredients are well combined and the mixture becomes frothy. 3. Add a handful of ice cubes to the blender and blend again until the shake becomes thick and creamy. 4. Taste the shake and adjust the sweetness or coffee strength according to your preference. 5. Pour the Mexican Coffee Protein Shake into two glasses. 6. Serve immediately and enjoy! Note: If you prefer a colder shake, you can add more ice cubes or refrigerate the shake for a few minutes before serving.
