For 12 servings
Preheat your oven to 425°F (220°C). Line a 12-cup standard muffin tin with paper liners or grease thoroughly with non-stick spray.
In a large bowl, whisk together the all-purpose flour, protein powder, granulated sugar, baking powder, baking soda, salt, and poppy seeds until well combined.
In a separate medium bowl, whisk together the Greek yogurt, vegetable oil, egg, milk, lemon zest, fresh lemon juice, and vanilla extract until smooth.
Pour the wet ingredients into the dry ingredients. Stir gently with a spatula until just combined. Be careful not to overmix; a few lumps are perfectly fine.
Divide the batter evenly among the 12 prepared muffin cups, filling each about two-thirds full.
Bake for 5 minutes at 425°F (220°C), then, without opening the oven door, reduce the oven temperature to 375°F (190°C) and continue baking for another 12-15 minutes, or until a wooden skewer inserted into the center of a muffin comes out clean.
Remove the muffin tin from the oven and let the muffins cool in the tin for 5 minutes before transferring them to a wire rack to cool completely.
Serve warm or at room temperature. Enjoy your bright and protein-packed muffins!
What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1Do not overmix the batter! Overmixing develops gluten, leading to tough, chewy muffins instead of light and fluffy ones. Mix until just combined.
- 2Using room temperature wet ingredients (yogurt, egg, milk) helps them emulsify better and creates a smoother, more uniform batter.
- 3The initial high heat helps the muffins rise quickly, creating those desirable domed tops. Don't skip this step!
- 4Store cooled muffins in an airtight container at room temperature for up to 3 days, or freeze for up to 3 months. Thaw at room temperature or warm gently in the microwave.

Frequently asked questions
Yes, you can use your preferred protein powder (whey, casein, plant-based). Keep in mind that different protein powders can absorb liquid differently, so you might need to slightly adjust the amount of milk to achieve the right batter consistency.
