The Best Healthy Apple Crumble Pie With Oat Crust

Not gonna lie, this healthy version of a classic apple pie is pretty much the same as my mini pies from a few years ago, but it looks like their parent. Making this flourless healthy apple crumble pie with its amazing oatmeal crust and sugar-free apple filling from scratch might look like a huge undertaking, but it’s actually super easy. And the result is – the best autumn treat, but good for you!

I used no flour, but oats to prepare the crust and the streusel on top and apples, cinnamon and coconut oil for the filling of the pie. So, if you’re counting, we’re talking a gluten-free, flourless and refined-sugar free baking recipe with apples and it tastes amazing. It’s great for holidays, special occasions or whenever you’re in the mood for a fall dessert or even breakfast. It’s basically apple pie that you’ll want to eat every day (well if you choose the right apples – more on that later)!

Healthy Homemade Apple Crumble Pie

So this healthy apple crumble pie is generally flourless and vegan (use maple syrup, not honey!) as it’s made with oats and there are no eggs or butter or dairy or meat in this recipe. Shocking I know! Apple pie without meat? Are you kidding me? It will taste like nothing.

And you can use gluten-free oats to make it gluten-free, if you need to be eating this way.

Now, I topped mine with ice cream, because I was going through a phase when ice cream became one of my biggest cravings. Even though I hadn’t broken up with anyone and wasn’t starring in a romantic “comedy” from the 90’s, 2000’s or 2010’s. I even tried “healthy” ice cream and it wasn’t bad, but it’s just not the same.

Pick The Right Apples!

Okay, a bit of a warning: taste your apples before you make this. I made this healthy pie recently after I went apple picking with my sister and her family. All I can say: FREE APPLES. Who knew, they grow on trees! Surprise!!! I think we saved like 10 bucks from picking this many apples.

It was a super fun day, we also bounded with some sheep, we almost climbed trees and some of us stepped into sheep shit and things got messy. Help, it’s in my hair…

Even my little nephew got very excited because, free apples. He kept eating them and repeating “Apple. Pieeee.” He’s two and very cute.

Well, as cute as he might be, he didn’t get to eat the apple pie I made with those apples, because I don’t share food and his cuteness means nothing to me. I’m kidding, sometimes I’d share a little bit of my food with a dog or a cat. When I don’t like it a lot, of course. I’m not stupid.

The truth is those apples were sour.

When those apples met the lemons and limes on the kitchen counter, they just pointed and laughed for hours. As in, hydrochloric acid, which has a pH of 3 of is nothing to those apples…Such a loser, that HCl.

Still, the good eater that I am, I ate that pie with quite a lot of ice cream. Those were some fun sour mornings, I’m telling you. Baking a sour apple pie can make you quite an outsider and lonely. Nobody wants to touch that thing and listen to your constant complaints of how sour it is. Therefore, choose wisely.

And if you’re picking your own apples thinking you’re saving money and can maybe sell those apples or use them in like, I don’t know – an apple pie with oatmeal crust, because healthy – think again. Sometimes you’ll have to pay with your taste buds and lots of saliva to neutralize that acidic pH.

Okay, but if you make this healthy apple crumble pie with normal, sweet delicious apples that don’t taste like the world is about to end, you’ll be very happy. And you’ll have a healthy apple pie for dessert. Apple. Pieeee.

Update November 2020: I made this delicious pie again recently after I saw some of your feedback on Pinterest that reminded me of the recipe and made me believe in humanity again (I’ve now gotten a year older and way more dramatic if you can’t tell). So when I made the recipe again with my nephew, I decided it would be a good idea to make some step-by-step pictures, so this is what you’ll see below. I hope you enjoy the pie if you make it…I really loved it, but this time I actually spent 50 cents on apples. They were bittersweet. Sweet from the apples, bitter from having to pay for them.

Update 2025: 50 cents for apples????? hahahahaha. Also, this time I chose sweet apples, but the night before I made the recipe again, I had cut some onions on the cutting board that I used to chop apples. So I got an onion-infused apple pie. Still ate it. Apples – Good. Oat Crumble Crust – GOOOOD. Onion smell – GOOD. I feel like Joey from Friends, but younger and female. I also added ground the oats with some nuts to make the crust – I find it even more delicious! Just add 1:2 nuts to oats (pecans and walnuts are great) and use half the amount of coconut oil.

How To Make Healthy Apple Pie With Oat Crust

Preheat your oven! Then start making a crumbly crust in your food processor using ground oats, melted coconut oil and some water. You can also add in some nuts, but if you’re allergic to nuts or want to share this with a young child – leave out the nuts and use oats only.

Spread about 2/3 of this “dough” in a spring form using your hands. Keep the rest of the dough for the crumbly topping.

Peel and chop the apples, then saute them in a pan with some coconut oil and cinnamon. Make sure to taste the apples before adding on top of the crust.

Spread the apples over the oatmeal crust and top with the rest of the dough, making crumbles with your hands. Optionally, you can add walnuts or pecans here.

Bake at 180C/350F for about 30 minutes, but make sure to be checking after 20 minutes, because ovens are different! (this is very important when using honey for the crust)

Let the pie cool off to not burn your tongue, top with your favorite toppings and enjoy!
