Here is an easy apple crisp – gluten-free and vegan – that you toss into the slow cooker. It’s made with healthy oats and warming spices like cinnamon and ginger. While it cooks you can relax and enjoy the wonderful aroma of apples and spices filling your home. A few hours later, voila! A tasty dessert that is healthier than most versions too. There is less sugar and no butter (a little plant-based spread is used). This is a great homemade dessert for fall or any time of the year.
You can enjoy this slow cooker apple crisp warm right after it is cooked (let it cool a little) or later. But I do like to heat it up to serve later. You can microwave it for 20 – 30 seconds or heat it for a few minutes in the oven or on the stove (add a little water so it doesn’t burn).
It is great topped with a vegan frozen dessert/ice cream substitute too! I tried it with a vanilla oat milk chip frozen dessert.
Apples – I have used Granny Smith, Gala, and Honeycrisp apples in this recipe with great success. Pink Lady and Jonathans are also among the recommended varieties for baking.
Almond flour – I have updated this recipe to be gluten-free and switched the flour from white whole wheat to almond so more people can enjoy it.
Oats – Be sure to use gluten-free oats if you follow a gluten-free diet. Oats themselves are gluten-free but are often contaminated with wheat in processing if they are not a certified gluten-free brand. This recipe calls for quick oats, which are in smaller pieces than rolled oats.
Lemon juice – I suggest fresh lemon juice. You could also add in a little lemon zest for more flavor.
Cinnamon – I used regular cinnamon with the apples, then Ceylon cinnamon in the topping for fun. This has a lighter, fresher taste and I’m having fun experimenting with it. Regular cinnamon (cassia) has more heat.
Nutrition in Apples
A whole medium apple has 4.4 gm. of total fiber and 195 mg. of potassium with 95 calories (source: USDA Food Data Central). The soluble fiber in apples, like that in oatmeal and beans, can help lower blood cholesterol. Apples also have a high level of antioxidant activity from the phytochemicals they contain, such as quercetin and catechin.
This article about apple phytochemicals and their health benefits by Boyer and Liu (2004) discusses associations between eating apples and lower rates of cardiovascular disease, and potentially cancer.
How to Make Apple Crisp – Gluten-free and Vegan
The first step is to peel and chop the apples. As the peeler on my apple corer/slicer/peeler is sub-optimal, I decided to just do it the old-fashioned way. I peeled the apples with a vegetable peeler, quartered them, took out the core, and then sliced them crosswise. The time it takes to prepare this recipe will mainly depend on how long this step takes you.
Next, place the apples into the slow cooker. Add the maple syrup, almond flour, water, lemon juice, cinnamon, ginger, and salt. Mix these together.
Turn the slow cooker on high. Then, combine the topping ingredients into a crumbly mixture. I cut through it with a knife so the plant-based spread was in little pieces:
Sprinkle this mixture on top of the apples, cover it with the lid, and relax.
Let it cook for 2 – 3 hours or until the apples are soft enough to your liking. Slow cookers vary too. This one doesn’t have a tight seal. If I had used my other one, it probably would have been done a little sooner.
Can You Bake This Apple Crisp in the Oven?
Yes. Spray an 8″ x 8″ square casserole dish with nonstick spray, and cook at 350 degrees for 40 minutes. Cover with foil until the last 10 minutes of bakingto the topping doesn’t burn.
Can You Make This Apple Crisp Recipe in an Instant Pot?
Yes, you can use an Instant Pot instead of a slow cooker if you want. First, spray the Instant Pot liner with non-stick spray. Then, add the apples and other apple filling ingredients, but increase the water to 1/4 cup and stir. Then sprinkle the topping ingredients on top and don’t stir those in.
Cook on high pressure for 2 minutes. Carefully release the pressure after the 2 minutes are up and open the lid. This was tested in a 6-quart Instant Pot Duo. It took about 7 minutes for it to get up to pressure.
What Else Can You Add to Apple Crisp?
- Fresh or frozen blueberries, blackberries, or raspberries
- Fresh or dried cranberries
- Sliced almonds
- Chopped pecans or walnuts
- A chopped, peeled pear
Place this apple crisp in a covered container in the refrigerator for up to 3 days, or in the freezer for up to 3 months.

What a lovely and healthy idea!! Your recipe came at the perfect time!
So comforting and delicious.
Absolutely loved these, such a decadent but simple dessert.
I love that this recipe is friendly for several different dietary needs. Perfect for my work potlucks.
Do you have a recipe for the ice cream you topped this with?
No, I bought this at Aldi.
This recipe has all my votes. It is so easy to make and tastes wonderful.
I find slow cooker puddings fascinating and yet I’ve still not tried one, does the crumble topping go soggy or crisp in a slow cooker if you have the lid on? I love all these flavours and am super keen to try myself.
I think it depends on how long it cooks. Also, I find the topping to be crispier when made with almond flour than wheat flour.
I’m a big fan of using my slow cooker, but I’ve never tried this. It looks amazing and so easy to leave it to cook.
I’m always up for a healthier take on puddings and desserts. But what I really want to know is what’s the difference between a crisp and a crumble?
Hi Choclette, I do think of crisps as being baked in the oven to be, well, crispy! So maybe this is technically a crumble.
