Making Keto Cinnamon Protein Muffins is straightforward and enjoyable. Follow these steps to create your delicious breakfast treat:

1. Preheat Oven: Start by preheating your oven to 350°F (175°C). Line a muffin tin with paper liners or grease it lightly.
2. Mix Dry Ingredients: In a large mixing bowl, whisk together the almond flour, protein powder, baking powder, cinnamon, and salt until well combined.
3. Combine Wet Ingredients: In another bowl, beat the eggs. Then, add the almond milk, melted coconut oil, and vanilla extract. Mix until smooth.
4. Combine Mixtures: Pour the wet ingredients into the dry ingredients, and stir until just combined. Avoid overmixing—this will keep the muffins light and fluffy.
5. Sweeten the Batter: Fold the erythritol or your choice of sweetener into the batter, ensuring it is evenly distributed.
6. Fill Muffin Tin: Spoon the batter into the prepared muffin tin, filling each cup about two-thirds full.
7. Bake: Place the muffin tin in the preheated oven and bake for 20 minutes or until a toothpick inserted in the center comes out clean.
