How to Make Keto Blackberry Coffee Cake
To Make the Gluten Free Cake
In a separate bowl, mix together the eggs, sour cream, heavy cream, Swerve and vanilla.
Add in the dry ingredients and mix just until combined.
Dollop the blackberry jam over the top of the batter, then swirl it into the batter using a knife. Set aside while you make the sugar free crumble topping.
To Make the Gluten Free Crumb Topping
Pour the melted butter over the top and mix until well combined.
Sprinkle the crumb topping over the batter.
Gently press the crumbs into the batter slightly. This will help the topping stick to the coffee cake and not fall off when you cut into it.
Bake for 45-50 minutes or a toothpick, when inserted, comes out clean and the crumb topping is golden. Mine took exactly 50 minutes.
Store leftovers in an airtight container in the fridge for 5-7 days.

Tips For Making the Best Keto Coffee Cake
This Blackberry Coffee Cake is so easy to make and taste just like traditional coffee cake. Here are a few tried and true tips to ensure your coffee cake turns out perfect every time:
How to Get Perfect Coffee Cake Texture
By using a mix of both almond flour and oat fiber you'll get that authentic coffee cake texture that you’re looking for. Super fine almond flour works best in most any low carb or gluten-free desserts as a substitute for traditional flour and when mix with a little oat fiber, you just can't beat it.
What's the Best Sweetener for Keto Coffee Cake?
Swerve Confectioners is used in this recipe. It dissolves well in the batter and it taste a lot like regular sugar without having a funny aftertaste like a lot of artificial sweeteners. You can also use Allulose, Powdered, if that's what you have on hand.
What Makes the Best Gluten Free Crumb Topping?
The best brown sugar substitute I've found is Swerve Brown. It tastes and bakes just like brown sugar and makes the BEST sugar free crumb topping!
If you're eating this coffee cake like a dessert, you can add homemade whipped cream and a few fresh blackberries right on top for a little added decadence.
What is Oat Fiber? Is Oat Fiber Keto?
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.
