Crumble Topping


I love working with oat fiber.  It brings to low-carb baked goods what flour used to bring, a flour-y taste and flour-y texture.  This tasty crisp made with apple was just DELICIOUS!  I had 4 Gala apples I had bought for my husband (that he wasn’t eating)  that were going to go bad and were really past the crisp, eating stage.  So this is how I used those up!  My typical apple filling:  4 peeled, sliced apples tossed with a few tablespoons of water, a sprinkle of xanthan gum tp thicken, 1/4 c. Splenda or erythritol, along with a pinch of cinnamon and nutmeg.  Pour into non-stick pan or baking dish and dot with 2T. butter.

I made the crumble topping below and sprinkled HALF the crumble mixture over the fruit.  I zipped the other half up in a baggie and freeze for another use. Will keep frozen for 1 month. This is not Induction friendly, so wait until you reach Phase 2 of Atkins to enjoy this.  To make this MUCH lower carb, you could instead use peeled, grated jicama, sliced zucchini or chayote squash for half, or even all the apples in this, but cooking time will increase if you do.

1½ c. CarbQuik baking mix (or other low-carb bake mix)

½ c. (45 g) oat fiber (DO NOT use high carb oat flour! Not the same thing!)

2 T. cold butter

pinch salt

1/4-1/2 c. water, added slowly

1-2 T. granular erythritol

OPTIONAL:  ½ tsp. cinnamon

DIRECTIONS:  Preheat oven to 350º.  Into a medium bowl, measure out bake mix, oat fiber and salt.  Stir.  Using a fork, cut in the cold butter until crumbly and well incorporated into dry ingredients.  Slowly add 1/4 c. water and work in with fork.  Add more water by tablespoons, stirring after each addition until mixture begins to hold together into pea-sized clumps. When all appears to be mixed well, spoon out half the mixture into a ziploc bag and freeze for future use.  Using fingers, crumble the remaining topping onto your fruit crisp filling mixture.  Bake at 350º for about 30 minutes or until apples are tender and topping is browned nicely.  Serve hot or cold.

NUTRITIONAL INFO FOR TOPPING ONLY: Recipe makes enough for TWO 9″ round pans of apple or berry crisp. I get 4 servings from a 9″ pan.  (8 total servings in both pans).

Total recipe contains:  374 calories, 47g fat, 75.7g carbs, 67.7g fiber, 8 NET CARBS, 24g protein

1 single serving of topping (1/4 of 1 pan) contains: 45.5 cal, 3.1 g fiber, 9.5 g carbs, 8.5 g fiber, 1 NET CARB, 3 g protein

FOR THE CURIOUS: 1 Serving with apple filling made as described above:  219 calories, 18g fat, 39.4 g  carbs,  20.3 g  fiber, 19.1 g NET CARBS, 6.4 g  protein.  Yes, it’s really high carb using real apples, so you might prefer to cut the majority of carbs out and use berries or apple substitutes like jicama, chayote squash or zucchini in your filling!  Just sayin’ that most of the carbs here are in the filling, not the crumble topping. 😉

  1. Thanks Peggy! I have read good things about the LifeSource (I think that’s the brand in the silver package sold on Netrition) so I went ahead and ordered some bags from them.

  2. Hi Peggy, just a quick question. Do you have a preferred brand of oat fiber that you use? I have been using the NuNaturals because it comes in a bulk size, but I’ve noticed that it is a bit more fibrous in texture than Honeyville’s.

    1. I’ve bought both Honeyville’s and the 1# bags carries (sorry I can’t remember the brand they carry but it comes in a silver mylar bag). They are both VERY fine powders and perform well in baked goods. I’ve never used the NuNaturals.
