Ingredients You’ll Need

Simple ingredients. Cozy flavors. No drama.

Dry Ingredients

• 1½ cups oat flour – Blend oats if needed. DIY counts.
• 1 scoop vanilla protein powder – Whey works best for texture.
• 1½ tsp cinnamon – The star of the show.
• ½ tsp baking powder
• ½ tsp baking soda
• ¼ tsp salt – Always.

Wet Ingredients

• 2 eggs – Room temp if you remember.
• ⅓ cup honey or maple syrup – Sweet but not overpowering.
• ⅓ cup Greek yogurt – Keeps muffins soft and moist.
• ¼ cup milk (any kind) – Dairy or plant-based both work.
• 1 tsp vanilla extract

Add-Ins

• 1 cup finely chopped apple – Peel if you want. I won’t judge.
• Optional: chopped walnuts or pecans for crunch.

Key tip: Finely chopped apples = better texture. Big chunks get weird.

Step-by-Step Instructions

1. Preheat your oven to 350°F (175°C).
   Line a muffin tin or lightly grease it. Future-you will appreciate this.
2. Mix the dry ingredients.
   In a bowl, whisk oat flour, protein powder, cinnamon, baking powder, baking soda, and salt.
3. Mix the wet ingredients.
   In another bowl, whisk eggs, honey or maple syrup, Greek yogurt, milk, and vanilla until smooth.
4. Combine wet and dry.
   Pour wet ingredients into dry and stir gently. Don’t overmix. Muffins hate that.
5. Fold in apples (and nuts, if using).
   Distribute evenly so every muffin gets apple goodness.
6. Fill the muffin cups.
   About ¾ full. Don’t get greedy—they need room to rise.
7. Bake for 18–22 minutes.
   A toothpick should come out mostly clean. Moist crumbs are fine.
8. Cool before eating.
   Yes, even though they smell amazing. Let them set.

Common Mistakes to Avoid

Because muffin heartbreak is unnecessary.

• Using too much protein powder.
  One scoop is enough. More = dry muffins.
• Overmixing the batter.
  Stir just until combined. Lumps are okay.
• Skipping the yogurt.
  This is what keeps them soft. Don’t sabotage yourself.
• Cutting apples too big.
  Large chunks release too much moisture and mess with texture.
• Overbaking.
  Dry protein muffins are a crime. Pull them early if unsure.

Alternatives & Substitutions

Because your pantry has opinions.

• Gluten-free option:
  Oat flour already works—just make sure oats are certified GF.
• Egg-free version:
  Use 2 flax eggs. Texture will be slightly denser but still good.
• Lower sugar:
  Reduce sweetener to ¼ cup and rely on apples for sweetness.
• Extra protein:
  Add 1–2 tbsp cottage cheese or increase yogurt slightly.
• Spice upgrade:
  Add a pinch of nutmeg or cloves for extra cozy energy.

IMO, walnuts + apple + cinnamon is an elite combo.

FAQ (Because You’re Definitely Thinking These)

Do these muffins taste “protein-y”?
Nope. Cinnamon and apple cover everything beautifully.

Can I eat these for breakfast?
Absolutely. Pair with fruit or coffee and you’re set.

Why are my muffins dense?
Likely overmixing or too much protein powder. Easy fix next time.

How should I store them?
Airtight container in the fridge for up to 5 days. Freeze for longer storage.

Can I use applesauce instead of fresh apples?
You can, but texture changes. Fresh apples give better structure.

Are these kid-friendly?
Yes. Especially if you add a few chocolate chips.

Can I double the recipe?
Yes. Just bake in batches and don’t overcrowd the oven.

Final Thoughts

These Apple Cinnamon Protein Muffins are the kind of baked good that quietly becomes part of your routine. They’re soft, cozy, filling, and perfect for busy mornings or snack emergencies.

Make a batch. Let your kitchen smell amazing. Eat one warm. Eat another later straight from the fridge. That’s balance.

Now go bake something that feels like a hug—but with protein.
