Apple Cinnamon Protein Muffins

When fall rolls around, we often think of apples, as it’s their peak season and nothing tastes better than a fresh, sweet apple. Well, maybe in second place are these apple cinnamon muffins with added protein.

Made with only the best ingredients, these protein muffins bring you the fall-type flavors of apple, oats and cinnamon in perfect-sized snacks that you can enjoy at breakfast, at snack time, before or after a workout. We’re talking 140 calories per muffin with balanced macros — 18 grams of carbs, 4 grams of fat and 11 grams of protein.

Whey protein and Greek yogurt lend protein to the recipe, rolled oats and apple provide fiber, and those oats and Paleo flour serve as complex carbohydrates to provide steady energy.

Let’s learn to make up a batch in under 10 minutes prep time.

Ingredients for apple protein muffins

• Old-fashioned rolled oats: They provide complex carbohydrates, fiber (including beta-glucan), B vitamins and minerals such as magnesium and manganese. Oats add hearty texture, structure and a slightly nutty flavor while helping absorb moisture.

• Greek yogurt: It provides protein, calcium, phosphorus and vitamin B12 to support muscle and bone health. Greek yogurt adds moisture, richness and a slight tang while helping create soft, tender muffins.

• Ancient Nutrition’s Whey Protein Vanilla: It provides all nine essential amino acids, including leucine, to support muscle growth, maintenance and recovery. It also boosts the muffins' protein content while adding vanilla flavor and contributing to their structure.

• Apples: They provides fiber, including pectin, natural carbohydrates and antioxidant polyphenols that contribute to digestive health and overall nutrition. Apples add natural sweetness, moisture and fruity flavor, along with a soft texture.

• Paleo flour: Depending on the blend, Paleo flour can provide fiber, healthy fats, protein and minerals such as magnesium and manganese. It provides structure and helps hold the muffins together while creating a tender crumb.

• Eggs: They provide complete protein, choline, vitamin B12 and selenium. Eggs help bind the ingredients together, provide structure and help the muffins rise and maintain their shape.

• Butter: It provides dietary fat and small amounts of fat-soluble vitamins, particularly vitamin A. Butter adds richness, moisture and flavor while helping create a soft, tender texture.

• Cinnamon: It contains polyphenols and antioxidants. Cinnamon adds warm, naturally sweet flavor that complements the apples and enhances the muffins without requiring additional sugar.

How to make apple cinnamon protein muffins

These apple cinnamon protein muffins are surprisingly easy to make and come together in just a few simple steps. Featuring old-fashioned oats, Greek yogurt, Ancient Nutrition’s Vanilla Whey Protein, fresh apples and cinnamon, they're a delicious option for breakfast, an afternoon snack or a post-workout treat.

Start by preheating your oven to 350°F. Prepare a 12-cup muffin pan by lightly greasing each cup with coconut oil or avocado oil, or use paper muffin liners for easier cleanup. A silicone muffin pan also works well.

In a large mixing bowl, combine the wet ingredients. First, beat the egg, then add Greek yogurt, vanilla extract, maple syrup and melted butter. Stir until the mixture is smooth and well blended.

Next, add in the old-fashioned rolled oats, Paleo flour, whey protein, cinnamon, baking powder, baking soda and salt. Gently mix until the dry and wet ingredients are just combined, being careful not to overmix, which can make the muffins dense.

Fold in the diced apples, distributing them evenly throughout the batter so every muffin gets plenty of sweet apple flavor.

Divide the batter evenly among the 12 prepared muffin cups. Place the pan in the oven and bake for approximately 20 minutes, or until the tops are lightly golden and a toothpick inserted into the center comes out clean or with a few moist crumbs.

Remove the muffins from the oven and let them cool in the pan for about five minutes. Then transfer them to a wire rack to cool completely. Enjoy one warm for a comforting apple cinnamon treat, or save a batch for convenient breakfasts and snacks throughout the week.

Keep the muffins in the refrigerator for up to five days, or in the freezer for up to three months. Because these muffins contain Greek yogurt and fresh apples, refrigerating them is the safer option that keeping them out.

Frequently asked questions

What’s the best type of apple to use in these protein muffins?

Honeycrisp, Fuji and Granny Smith apples are excellent choices for apple cinnamon protein muffins because they hold their shape during baking and provide great flavor. Honeycrisp apples offer a crisp texture and balanced sweetness, Fuji apples are naturally sweet and juicy, and Granny Smith apples add a tart flavor that complements the cinnamon. Honeycrisp is often the top pick because it combines sweetness, texture and flavor.

Can I make apple cinnamon protein muffins gluten-free?

Yes, use certified gluten-free rolled oats and a gluten-free Paleo flour blend to make these muffins gluten-free.

Can I substitute another protein powder for whey protein?

Yes, you can use vanilla bone broth protein or a plant-based protein powder, although you may need to adjust the liquid ingredients because different protein powders absorb moisture differently.

Can I freeze apple cinnamon protein muffins?

Yes, let the muffins cool completely, then store them in an airtight freezer-safe container for up to three months and thaw before enjoying.
