Protein Granola Recipe

This homemade protein granola recipe is crunchy, naturally sweetened with maple syrup, and packed with nuts, seeds, and protein powder.

Granola is one of those foods I’ve been making at home for years, and this might be the best recipe yet!! I’ve made so many different variations from tahini granola to buckwheat granola to a healthy granola recipe without sweeteners. It tastes like a Reese’s cup thanks to the vanilla and peanut butter combination!

Protein Granola Recipe

This protein granola recipe has a boost in protein and flavor from my favorite vanilla bean protein powder by Ancient Nutrition. It bakes right into the clusters and you can’t detect any texture difference, but the flavor is fantastic! Plus, the peanut butter and vanilla together give it a Reese’s flavor. AND lastly, it clumps up perfectly! It reminds me of the Cville Cluster granola we used to make at Great Harvest. I love it over Greek yogurt or cottage cheese, with a splash of milk, or straight out of the canister, cluster by cluster, as a snack!

How To Make Granola Crunchy and Clumpy

I did a little research on the food science of granola texture to make this granola both crunchy and clumpy. I learned that when oats, fat, and sugar heat together, the sugars caramelize and the starches set, which is what creates the crunch. The fat coats each oat and seed, acting as a conductor for even toasting, while the sweetener binds everything into clusters as it cools. The cooling period isn’t just about temperature — it’s when the sugars harden and lock the clusters together. If you stir it too early or break it up too soon, you lose the clusters you worked for. So don’t stir this one!

Does Granola Have Protein?

Traditional granola does have some protein — oats naturally contain about 5 grams per half cup, and nuts and seeds add more. But most classic granola recipes yield 5–8 grams of protein per serving depending on ingredients. This recipe bumps that number up to 10 grams of protein per 1/3-cup serving (along with roughly 280 calories, 17 grams of fat, and 25 grams of carbohydrates).

Why I Use Ancient Nutrition Protein Powder

I’ve tried a lot of protein powders, and Ancient Nutrition Vanilla Whey is my favorite. It has a vanilla bean flavor, which I prefer to a French vanilla.

As an RD, I also appreciate that Ancient Nutrition uses grass-fed milk and includes collagen. I went to a conference with Ancient Nutrition in 2025 and learned a lot about their product quality. The protein comes from grass-fed whey and organic regenerative A2/A2 milk protein — from cows raised without hormones or antibiotics. A2 milk protein comes from cows that produce only the A2 type of beta-casein, which tends to be easier to digest — worth noting if you’ve ever had a sensitive stomach with conventional whey. There’s also the bonus ingredient: eggshell membrane collagen, which supports healthy joints, improves skin appearance, and offers other benefits. It’s also gluten-free, and certified carbon neutral.

Plant-based powders can work in this recipe too, but they tend to produce a slightly denser texture. If that’s what you use, go for it — just know the clusters may be a little less crunchy.

How To Make High Protein Granola

The process is simple: mix your dry ingredients, stir in your wet ingredients, spread on a baking sheet, and bake. The key to clusters is pressing the mixture down firmly before it goes in the oven and not stirring it while it bakes. Let it set undisturbed, and you’ll get those satisfying clusters.

The whole process takes about 30 minutes from start to finish, plus cooling time. Let it cool completely at room temperature before breaking it apart and storing.

Ingredients

• 2 cups rolled oats (old-fashioned, not quick oats)
• 1 scoop (about ¼ cup) Ancient Nutrition Vanilla Whey Protein
• ½ cup pumpkin seeds (can sub sunflower seeds)
• ½ cup mixed nuts (almonds, cashews, or pecans — roughly chopped)
• 2 tablespoons chia seeds
• ½ teaspoon cinnamon
• ¼ teaspoon sea salt
• 1/3 cup maple syrup
• 3 tablespoons neutral oil or melted coconut oil
• 1 teaspoon vanilla extract
• 2 tablespoons peanut butter

Instructions

Step 1: Preheat and Prep

Preheat your oven to 325°F.

Step 2: Mix Dry Ingredients

In a large bowl, combine the rolled oats, protein powder, pumpkin seeds, chopped nuts, chia seeds, cinnamon, and salt. Stir until well combined.

Step 3: Mix Wet Ingredients

In a small bowl or measuring cup, whisk together the maple syrup, oil, vanilla extract, and nut butter. If your nut butter is stiff, warm it slightly so it blends smoothly into the maple syrup mixture.

Step 4: Combine and Toss

Pour the wet mixture over the dry ingredients and stir well until everything is thoroughly coated. Every oat and seed should look glossy.

Step 5: Spread and Press

Transfer the mixture to your baking sheet and spread into an even layer. Then press it down firmly with the back of a spatula or your hands. This step is the secret to getting clusters instead of loose crumbles. The more compact the mixture, the bigger the clusters.

Step 6: Bake

Bake for 22–25 minutes, until the edges are golden and the center looks set. Do not stir. Mine was very brown at 22 minutes, so watch your oven at the end.

Step 7: Cool at Room Temperature

Remove the pan from the oven and let it cool completely at room temperature — at least 30 minutes. This is where the magic happens. It will feel soft when it first comes out; it firms up into crunchy clusters as it cools.

Once fully cooled, break it into pieces and transfer to a jar or airtight container.

Step 8: Store and Enjoy

Store at room temperature in an airtight container for up to 2 weeks.

Serve over Greek yogurt, with milk, on smoothie bowls, or straight as a snack.

Tips & Notes

Don’t Overbake

Remove the granola when it looks just golden — it’ll crisp up more as it cools, so if you wait until it looks fully done in the oven, it may end up too dark.

Make It Your Own

Dried cranberries, coconut flakes, or dark chocolate chips can be stirred in after baking (not during — chocolate melts, fruit dries out further).
