Ingredients You’ll Need

This recipe makes 12 muffins.

Dry Ingredients

Ingredient	Quantity
All-purpose flour	1½ cups (180 g)
Vanilla protein powder	½ cup (about 50 g)
Baking powder	1½ tsp
Baking soda	½ tsp
Ground cinnamon	1½ tsp
Salt	¼ tsp

Wet Ingredients

Ingredient	Quantity
Large eggs	2
Plain Greek yogurt	¾ cup (170 g)
Milk	½ cup (120 ml)
Unsweetened applesauce	½ cup (120 g)

Apples

• Apples: 1½ cups (about 180 g) peeled and diced apples, or approximately 2 medium apples.
• Best varieties: Honeycrisp, Gala, Fuji, or Granny Smith all work well.
• How to prepare: Peel the apples, remove the cores and seeds, then cut them into small pieces.

How to Make High Protein Apple Cinnamon Muffins

1. Prepare the Oven and Muffin Pan

Preheat your oven to 375°F (190°C) so it reaches the right temperature before the muffins go in.

Line a 12-cup muffin pan with paper liners, or lightly grease each cup with cooking spray or a little oil.

Having the pan ready before mixing the batter helps you get the muffins into the oven quickly once the baking powder and baking soda are activated.

2. Combine the Dry Ingredients

Add 1½ cups all-purpose flour, ½ cup protein powder, 1½ teaspoons baking powder, ½ teaspoon baking soda, 1½ teaspoons cinnamon, and ¼ teaspoon salt to a large mixing bowl.

Whisk everything together until the protein powder and spices are evenly distributed throughout the flour.

This step helps prevent pockets of baking powder, salt, or protein powder from ending up in individual muffins.

3. Mix the Wet Ingredients

In a separate bowl, whisk together 2 eggs, ¾ cup Greek yogurt, ½ cup milk, ½ cup applesauce, ¼ cup maple syrup or honey, and 1 teaspoon vanilla extract.

Mix until the ingredients are smooth and well combined.

A few small streaks of yogurt are fine, so there is no need to keep mixing once everything is evenly incorporated.

4. Make the Muffin Batter

Pour the wet mixture into the bowl with the dry ingredients.

Stir gently with a spatula or wooden spoon until the flour is almost completely incorporated.

Be careful not to overmix, as too much stirring can make the muffins dense instead of light and tender.

Add 1½ cups of finely diced apples and gently fold them into the batter.

Stop mixing as soon as the apples are evenly spread throughout the batter and no large pockets of dry flour remain.

The finished batter should be thick and scoopable rather than runny.

5. Fill and Bake

Divide the batter evenly between the 12 prepared muffin cups, filling each one about three-quarters full.

For evenly sized muffins, use a cookie scoop or measuring cup to portion the batter.

Place the pan in the preheated oven and bake for approximately 18–22 minutes.

The muffins are ready when the tops are lightly golden and a toothpick inserted into the center comes out clean or with a few moist crumbs.

Avoid overbaking, since protein-rich muffins can become dry if left in the oven too long.

Let the muffins cool in the pan for about 5 minutes, then transfer them to a wire rack to finish cooling.

They can be enjoyed warm, but allowing them to cool slightly gives the crumb time to set and makes them easier to handle.

Tips for Making the Best Protein Apple Cinnamon Muffins

• Avoid overmixing: Stir the batter just until the ingredients are combined to keep the muffins light and tender.
• Measure protein powder accurately: Too much protein powder can make the muffins dry and dense.
• Use Greek yogurt: It adds moisture and extra protein while helping create a soft crumb.
• Dice apples evenly: Cut the apples into small, similar-sized pieces so they distribute evenly and bake at the same rate.
• Don’t overbake: Remove the muffins when a toothpick comes out clean or with a few moist crumbs to prevent dryness.
• Let them cool: Allow the muffins to cool before storing so excess moisture doesn’t build up in the container.

Best Apples for Apple Cinnamon Muffins

The best apples for these muffins are firm enough to hold their shape while becoming tender in the oven.

• Honeycrisp is an excellent choice if you like a sweet, juicy apple with a little crunch.
• Gala apples have a mild sweetness that blends easily with the cinnamon without overpowering the other flavors.
• Granny Smith apples add a bright, tart flavor that creates a nice contrast with the sweet muffin batter.
• Fuji apples are naturally sweet and juicy, making them a good option when you want a sweeter muffin without adding much extra sugar.
• Pink Lady apples offer a balanced sweet-tart flavor and stay pleasantly firm when baked.

Sweet apples such as Gala and Fuji will give the muffins a softer, sweeter apple flavor.

Tart apples such as Granny Smith create more contrast, making the cinnamon and sweetness of the muffin stand out.

You can also combine a sweet apple with a tart variety for a more balanced flavor.

How to Increase the Protein in These Muffins

Greek yogurt is one of the easiest ways to add protein while keeping these muffins moist and tender.

For an even higher protein content, choose a protein powder that provides plenty of protein without adding excessive calories.

You can also replace one or both whole eggs with additional egg whites, which increases the protein while keeping the batter relatively light.

It may be tempting to simply add more protein powder, but too much can absorb excess moisture and leave the muffins dry, dense, or slightly chewy.

For the best texture, increase protein gradually and balance any extra protein powder with enough moisture from ingredients such as Greek yogurt, milk, or applesauce.

Variations and Substitutions

Make Them With Oat Flour

You can replace the all-purpose flour with 1½ cups (about 150 g) oat flour for a slightly heartier muffin with a gentle oat flavor.

Oat flour absorbs moisture differently from regular flour, so the muffins may be a little softer and more tender.

For the best texture, avoid overmixing the batter and let the baked muffins cool before serving.

Make Them Without Protein Powder

If you don’t want to use protein powder, simply leave it out and replace it with ½ cup (about 60 g) additional flour.

The muffins will still be moist and flavorful, but they will have less protein than the original recipe.

Because protein powder can affect the texture, the muffins may also be slightly less dense and more cake-like without it.

Add Nuts

Chopped walnuts or pecans make a delicious addition to the apple and cinnamon combination.

Stir about ½ cup (60 g) of chopped nuts into the batter along with the diced apples.

For extra flavor and crunch, you can lightly toast the nuts before adding them.

Add Raisins

Raisins add little bursts of sweetness and a chewy texture that work especially well with apples and cinnamon.

Fold ½ cup (75 g) of raisins into the batter along with the apples.

If your apples are already very sweet, you can reduce the maple syrup or honey slightly to keep the muffins balanced.

Make Them Dairy-Free

To make the muffins dairy-free, replace the Greek yogurt with an equal amount of plain dairy-free yogurt.

Use your favorite unsweetened plant-based milk, such as almond, soy, or oat milk, in place of regular milk.

Check that your protein powder is also dairy-free if you need the entire recipe to avoid dairy.

Make Them Gluten-Free

Replace the all-purpose flour with 1½ cups of a gluten-free 1:1 baking flour blend.

Choose a blend designed to replace regular flour cup-for-cup, preferably one that already contains xanthan gum.

Check the labels on your protein powder and other ingredients as well if you need the muffins to be completely gluten-free.

How to Store Protein Apple Cinnamon Muffins

Store the cooled muffins in an airtight container to help keep them soft and prevent them from drying out.

At room temperature, they can be kept for up to 2 days in a cool, dry place away from direct sunlight.

For longer storage, place the muffins in an airtight container and refrigerate them for up to 5 days.

Refrigeration can make muffins slightly firmer, so warm one in the microwave for a few seconds before serving if you prefer a softer texture.

Let the muffins cool completely before closing the container, as trapped heat can create condensation and make the tops damp.

For the best results, place a sheet of paper towel underneath the muffins and another on top to absorb excess moisture.

Avoid storing the muffins uncovered, as exposure to air will cause them to lose moisture and become stale more quickly.

Can You Freeze Apple Cinnamon Muffins?

Yes, these apple cinnamon muffins freeze well, making them a convenient option for breakfast or meal prep.

Allow the muffins to cool completely before freezing to prevent ice crystals and excess moisture from forming.

Wrap each muffin individually in plastic wrap or foil, then place the wrapped muffins in a freezer-safe bag or airtight container.

Freezing them individually makes it easy to take out only the number you need without thawing the whole batch.

For the best taste and texture, use the frozen muffins within 2–3 months.

To thaw, leave a muffin at room temperature for about 1–2 hours, or place it in the refrigerator overnight.

For a quicker option, microwave a frozen muffin for 20–30 seconds, then check the center and heat it for a few more seconds if needed.

You can also warm thawed muffins in a 300°F (150°C) oven for about 5–10 minutes to restore their soft texture and fresh-baked warmth.

How to Serve High Protein Apple Cinnamon Muffins

• Serve with Greek yogurt: Add a spoonful of Greek yogurt for extra creaminess and protein.
• Pair with eggs: Enjoy a muffin with scrambled or boiled eggs for a more filling, high-protein breakfast.
• Enjoy with coffee or tea: The warm apple and cinnamon flavors pair beautifully with your favorite hot drink.
• Add nut butter: Spread almond, peanut, or cashew butter on a muffin for extra protein, healthy fats, and richness.
