Low Sugar Apple Crumble

Fall is my absolute favorite season and apple crumble is something on my “must make” every year. Honestly, what warms the soul more than a warm bowl of apple crisp and the smell of baking apples and cinnamon? I truly think nothing.

This is actually my mother’s recipe and is near and dear to my heart. She would often make apple crumble when apples in the crisper drawer were on their last leg. What a great way to use up that extra fruit!

Is Apple Crumble Healthy?

Of course! As many of you know, I take an “all foods fit” approach. I think any food can fit in a kidney friendly diet.

This low sugar apple crumble can absolutely fit in any healthy diet. I love fruit desserts. It is such a yummy way to add some natural sweetness – plus some extra fiber, vitamins and minerals!

This crumble also only has 9g of added sugar.

Low Sugar Apple Crumble Ingredients


Of course, low sugar apple crisp needs apples! I love to use a mix of apples for baked apple desserts. I usually add a few tart granny smiths for some crunch. And, some sweeter apples like fuji or gala.

You could easily swap apples for other fruits in this recipe. Try:

  • Peaches
  • Blueberries
  • Pears
  • Plums
  • Nectarines
  • Pineapple


Oats are key to any crumble! They give the dessert a little body and chewy texture. Any kind of oatmeal works here.

Brown Sugar

Yep! This recipe calls for some actual (real!) brown sugar. In my cooking, I generally prefer to use a little bit of the real stuff when it comes to sweetener. But, you could swap the brown sugar for Splenda if you prefer.


Old school, all purpose flour is what I usually use. You could use whole wheat for a little extra fiber.


Warm baking spices, like cinnamon, are necessary for any apple dessert in my opinion! Adding cinnamon and other spices helps add extra flavor and keep the sugar down.

Add a pinch of nutmeg or allspice too if you are feeling fancy!


Just a pinch! Don’t worry, the total sodium comes out to only 17mg per serving.


We need a little fat to help the crumble get crispy and golden brown. I always go with unsalted butter to help keep the sodium down.

Can I Add Ice Cream?

Of course! Of course, adding ice cream does add sugar, potassium and phosphorus as well. Make sure to take those into consideration! Whipped cream is a great way to add a little creaminess with less sugar.

Happy Eating!

  1. I’m gonna try making this recipe this weekend but without cinnamon. I thought cinnamon was a high oxalate spice? Do you have a list of spices & the oxalate content?
    Thank you!

      Hi Linda! I hope you love the recipe. It is truly one of my favorites.
      The amount of oxalate you get from any spice in realistic amounts you would use in a recipe is minimal. If you were consuming tablespoons of cinnamon at once, it might add up. But, using a teaspoon here and there for an entire recipe, it doesn’t really matter. I do include oxalate amounts for all of my recipes in the nutrition facts info!

  2. Great ‘Crumble’, and everyone I shared it with agreed (thanks to your mom)!
    2 questions- Do you have a list of breads to bake (for stage 2/3 CKD)?
    Question 2- do you have, or know of, a large list of phosphorus in a variety of foods that includes the amount we humans actually absorb?
    Many thanks – Julie

      Thank you Julie! I don’t have a list of breads that are okay for CKD – in general I advise finding a bread that has at least 3 g of fiber per slice and that doesn’t have phosphate additives. This article addresses the difference between phosphorus absorption between different kinds of foods!

        1. Melanie Betz MS, RD, CSR, CSG

          Hello! Mushrooms are not very high in phosphorus to begin with. And, the percentage would be very low (around 30% or so) since they are a plant food!
