The Best Low Fat High Protein Apple Crumble Recipe

Hi all, I was searching for a quick and easy apple crumble recipe and couldn’t find an appealing vegan option. So, I’ve researched for you and come up with a great vegan protein apple crumble recipe that’s perfect for the school holidays or even those busy weeknights when you’re in for a single serving (or 4) of apple crumble!

What is Apple Crumble?

Apple crumble is a popular dessert that consists of baked spiced apples topped with a layer of crumbly, buttery, and often oat-based topping. It’s a comforting and delicious dessert that combines the sweetness and tartness of cooked apples with a crunchy, flavorful topping.

The Fascinating History of Apple Crumble

Apple crumble is a traditional British dessert, and it’s basically just like apple pie—except it doesn’t have any pastry. Instead, you mix up some flour and butter until it forms tiny crumbles, then sprinkle those on top of stewed apples.

That’s right: it’s an alternative to the pastry-based apple pie that was so popular before the war. The difference between the two? Well, one has pastry and one doesn’t!

After World War II ended, people were having trouble getting flour and butter from rationing—so they started making their own desserts instead of relying on store-bought items. And that’s how this delicious dish came about!

Ingredients and Substitutions

Apple: it’s not an apple crumble if there’s no apple. Use whatever apple you would like, but traditionally people tend to use more sour apples. However I just had red delicious apples on hand, so I used that.

Oats: Gluten-free if necessary. This is to add some texture, fibre and nutrients to the dessert (even though I eat it for breakfast).

Vegan Vanilla Protein Powder: I use this one, but if you have a pumpkin or apple pie-flavoured vegan protein powder, feel free to use that! The protein powder should be sweetened though (mine’s sweetened with stevia), it’s the main source of sweetness in the topping.

Apple pie spice: including ground cinnamon, ginger, cardamom and nutmeg. These spices make a huge difference!

Lemon juice – for a slight tang to pair with the protein apple crumble
