    I take coffee crumb cake to the next level,  add fresh blueberries and make it into a loaf.  One of my favorite things in the world is a crumb topping!  I could literally pick it off and just eat that, honestly!  

    I've been baking things with crumb topping for years, but since Keto, I've had to get creative in what I use in place of flour and brown sugar.

    Enter Brown Swerve!  If you've never tried it, it's fantastic! It looks, tastes and bakes exactly like brown sugar and is just perfect in this topping!

    The texture of this blueberry loaf is absolutely perfect, thanks to the Oat Fiber that I use.  It adds a very cake-like texture without adding carbs, just plenty of fiber! But, please be aware, brands do matter with Oat Fiber.  

    Blueberry Crumb Loaf on cutting board

    I use Lifesource Oat Fiber, which I purchase on Amazon, it's incredibly mild in flavor and ground to a very fine powder.  There are other brands of oat fiber out there that have a stronger flavor, so if you don't buy Lifesource, be sure to read the customer reviews first!

    What's in Keto Blueberry Loaf

    • Super fine almond flour
    • Oat Fiber
    • Swerve Confectioners 
    • Brown Swerve
    • Blueberries
    • Eggs
    • Sour cream
    • Heavy cream
    • Grass-fed butter
    • Baking powder
    • Vanilla extract
    • Lemon
    • Walnuts
    • Ground cinnamon
    • Ground nutmeg
    • Salt

    *Exact measurements are listed in the recipe card below.

    How to Make Low Carb Blueberry Crumb Loaf

    Preheat oven to 325F.

    Blueberry Crumb Loaf - Keto, Low Carb & Gluten Free

    Add all the ingredients for the crumb topping to a bowl, except the butter and mix together.

    Pour in the melted butter and mix until combined, then set aside.

    Add the flour, baking powder, oat fiber and salt to a bowl and whisk together, then set aside.

    Then add all the remaining ingredients, except the blueberries, to a large mixing bowl and mix using a hand mixer for about 30 seconds.

    Add in the dry ingredients and continue mixing.

    Blueberry Crumb Loaf - Keto, Low Carb & Gluten Free

    Fold in the blueberries gently, then pour into a 9" x 5" nonstick loaf pan that's been sprayed with nonstick spray (I used coconut oil spray).  

    If your pan isn't nonstick, I would line it with parchment paper.  Smooth the top using your spatula and top with the reserved crumb topping.

    Bake for 45-50 minutes or until a toothpick, when inserted, comes out clean.

    Can I Freeze Blueberry Crumb Cake?

    You sure can! In fact, if you're in a baking mood and would like to make a couple of these Keto coffee cakes, you can freeze them and have a grab and go snack anytime you'd like.

    To properly freeze it and for optimal freshness, allow the crumb cake to completely cool. Slice into the portion sizes you'd like and double wrap it in plastic wrap for up to a couple of months. Alternately, you can freeze the unsliced loaf the same way, if you choose.

    What are the Carbs in Blueberries?

    There are 17 net carbs in one cup of blueberries, but this blueberry crumb cake recipe only uses ⅔ cup which is split amongst 12 servings. That's under 1.5 carbs per serving!

    Is Oat Fiber Keto?  Is Oat Fiber the Same as Oat Flour?

    Oat Fiber is a key ingredient in this recipe, because it gives a more traditional texture. The Oat Fiber that I use is made by Lifesource Foods and I highly recommend it. They grind it to a very fine powder and has a very mild flavor.

    Oat Fiber is not the same as Oat Flour, which is made from grinding oats.  Oat Fiber is made from grinding the outer husks of oats and is pure insoluble fiber. Insoluble fiber doesn't dissolve in water and isn't broken down in the digestive tract, so it has zero net carbs.

    • 3 eggs
    • ½ cup sour cream
    • ¼ cup heavy cream
    • ½ cup  swerve confectioners
    • 2 teaspoons baking powder
    • 1 ½ teaspoons vanilla extract
    • zest of 1 lemon
    • Pinch of salt

    For the Crumb Topping

    • ⅔ cup  super fine almond flour
    • 3 tablespoons walnuts, chopped
    • 3 tablespoons grass fed butter, melted
    • ¼ teaspoon ground cinnamon
    • ¼ cup Brown Swerve
    • ⅛ teaspoon ground nutmeg

    INSTRUCTIONS

    • Preheat oven to 325F.
    • Add all the ingredients for the crumb topping to a bowl, except the butter and mix together.  Pour in the melted butter and mix until combined, then set aside.
    • Add the flour, baking powder, oat fiber and salt to a bowl and whisk together, then set aside.

    RECIPE NOTES

    The Oat Fiber is important in this recipe, as it gives a great bread-like texture. I use Lifesource Foods Oat Fiber 500, because it’s ground to a fine powder and has a very mild flavor.
    Oat Fiber is not the same as Oat Flour, which is made from grinding oats.  Oat Fiber is made from grinding the outer husks of oats and is pure insoluble fiber. Insoluble fiber does not dissolve in water and is not broken down in the digestive tract, so it’s Low Carb and Keto friendly.

      Hi,
      I was just wondering how to adjust baking time/temperature if I were to do this in a 8x8 or 9x9, as I do not have a loaf pan!

      Thanks!

      Is this really 6 net carbs per serving? The loaf is 12 servings so that would be a very small amount for the amount of carbs. Am I reading that right?

      Hi this is a very good recipe
      i used 2T psyllium husk and 4T coconut flour as I had no oat fiber.
      used pecan meal and golden swerve.
      covered my frozen blueberries with coconut flour before adding them.
      would make it again

      This cake is so good! I didn't have heavy cream so just used additional sour cream, along with powdered monk fruit instead of Swerve Confectioners for the sweetener . And I used hazelnuts in the crumb topping because I have an allergy to walnuts. So yummy.

      I appreciate the time you have spent developing recipes that many probably don't have time to do so that lots of us can enjoy healthier options!

        I've honestly never tried that before, so I can't say how it might turn out. Psyllium Husk powder and a little coconut flour might be a better substitute, but Oat Fiber still really works best.

          Hi Kayla,
          There really isn't anything that will work as well, but you can maybe try a combination of psyllium husk powder and coconut flour. You might need to add a little more liquid as well.

        Hi Ana,
        I'm glad to hear you're a believer as well and that you like the site 🙂 I can't say how psyllium husk powder would work to be honest, because I haven't tried it. I would try to use the oat fiber if possible, it's really what gives this loaf such great texture.

      This looks really yummy, but I live in Australia and I haven’t been able to find Swerve Brown Sugar. Is there a way around this!

      I love today’s verse too. Last week an uncle of mine who lives in Virginia was buried. My comfort is in knowing he is now with our Saviour in heaven and I will see him when I get there.

        Hi Marji,
        I'm so sorry to hear about your uncle! But as you said, you can rest knowing he is with our Lord and in a much better place than we are. You will get to spend eternity with him and our Lord, what a comfort indeed! On the brown swerve, I'm not sure if granular would work instead, because I've never tried it. If there is another brown sugar substitute that is available to you there, that should work. Like brown sugar, it gives it a molasses sort of flavor and texture that's different from regular erythritol. I'm not sure what else you could try honestly, possibly a tiny bit (1/2 teaspoon maybe) of blackstrap molasses and a few drops of maple extract?

        Hi Marji, you can get Sukrin Gold in Australia which is a brown sugar substitute.
