Step-by-Step Instructions
- Preheat the oven.
175°C / 350°F. Line a muffin tin or use silicone cups. - Mix dry ingredients.
In a bowl, combine oats/protein flour, protein powder, baking powder, baking soda, and salt. - Mix wet ingredients.
In another bowl, whisk eggs, Greek yogurt, lemon juice, lemon zest, sweetener, and vanilla. - Combine wet + dry.
Gently fold together. Don’t overmix—fluffy muffins > dense bricks. - Add extras.
Fold in poppy seeds or chocolate chips if desired. - Spoon into muffin tin.
Fill about ¾ full for nice rise. - Bake.
18–22 minutes, until a toothpick comes out mostly clean. - Cool & enjoy.
Let them cool slightly before eating. Optional: drizzle with sugar-free lemon glaze.
Common Mistakes to Avoid
- Skipping the lemon zest.
The zest = magic. Don’t cheat yourself. - Overmixing the batter.
Muffins become dense and sad. Fold gently. - Using thin yogurt.
Thick yogurt = tender texture. Thin yogurt = dry muffins. - Underbaking or overbaking.
Check with a toothpick. Slightly golden tops = perfection.
Alternatives & Substitutions
- Gluten-free: Use certified gluten-free oats or oat flour.
- Dairy-free: Plant-based yogurt + vegan protein powder.
- Lower carb: Almond flour + sugar-free sweetener.
- Extra protein: Add an egg white or two.
- Flavor twists: Add blueberries, raspberries, or orange zest instead of lemon.
IMO, poppy seeds are the classic vibe—you just can’t skip them.
