These Greek yogurt chocolate protein muffins are soft, rich, and deeply chocolatey, with about 10 grams of protein per muffin. The Greek yogurt keeps them incredibly moist while naturally boosting the protein, and the cocoa powder with dark chocolate chips adds a rich chocolate flavor.
Preheat the oven to 350°F (180°C). Lightly grease a muffin tin or line it with paper liners. Set aside.
In a large mixing bowl, crack the 4 eggs and add the vanilla extract. Using a whisk or hand mixer, beat for 1–2 minutes until the mixture becomes light and slightly frothy.
Add the Greek yogurt and mix until smooth and well combined.
Stir in the protein powder, sweetener, coconut flour, cocoa powder, and baking powder. Mix until a thick, smooth batter forms and there are no visible dry spots.
Using a spatula, gently fold in the chocolate chips or chopped dark chocolate.
Divide the batter evenly between 12 muffin cups, filling each about ¾ full. If you like, sprinkle a few extra chocolate chips on top.
Bake for 20–25 minutes, until the tops are set and slightly firm to the touch.
Insert a toothpick into the center of a muffin. If it comes out clean or with a few crumbs, the muffins are ready.
Let the muffins cool in the tin for 5 minutes, then transfer them to a wire rack to cool completely before serving.
