The Comfort of Crumble, Powered by Protein

From College Classic to Post-Workout Treat

During my college years, high-protein apple crumble was the dessert I made on repeat. All I needed were a few apples, some oats, and brown sugar. Simple. Affordable. Comforting. But years later, as I got into strength training and started looking more closely at what I ate, I realized that my favorite comfort dish was lacking something important: protein.

So, I recreated it. This high-protein apple crumble keeps the heart of the original—warm cinnamon apples and a golden-baked topping—but sneaks in a protein punch that makes it perfect for breakfast or post-gym recovery. I used pea protein, but whey or casein both work well, depending on your dietary preferences.

Now, instead of just satisfying a sweet tooth, this crumble actually helps me hit my protein targets. It’s become one of those go-to recipes I never get bored of.

Great for Every Diet—And Every Craving

Whether you’re plant-based, gluten-free, or somewhere in between, this recipe has your back. It uses vegan butter and unsweetened applesauce to bring moisture and richness to the topping without any dairy or excess fat. The oats offer a hearty crunch, and the sugar-free brown sugar substitute keeps things sweet but low-glycemic.

The Power of Protein in Every Crumble

Why Protein in Dessert Works

Adding protein to your dessert might sound like a gym bro trend, but it’s actually a smart nutritional move. Protein keeps you fuller for longer and supports muscle repair. In a dish like this high-protein apple crumble, that means you can enjoy it as a snack or even a small meal.

Instead of traditional all-purpose flour, we’re using protein powder. It binds the ingredients together while adding flavor and nutrients. If you’re using an unflavored powder, just adjust the sweetener slightly for balance. I recommend pea protein for a vegan version, but whey concentrate gives it a softer texture.

You can see how I’ve used this trick in my other recipes too, like the Air Fryer Protein Zucchini Muffins or the rich Pumpkin Protein Cheesecake, which also turn dessert into something a little more balanced.

Crumble vs. Crisp—What’s the Difference?

If you’ve ever wondered what separates a crumble from a crisp, the answer is in the texture. Both start with baked fruit and a topping, but crisps typically include nuts or more butter for a crunchy finish. Crumbles, on the other hand, rely more on oats or flour for a soft and chewy top layer.

This high-protein apple crumble falls right in the middle—thanks to the oats, it’s hearty and satisfying, but the applesauce and vegan butter make the topping tender. Think of it as the perfect hybrid: a crisp that behaves like a crumble but with more benefits.
