How to Make the Best Gluten-Free Coffee Cake
There are a few steps to making this wonderful Low Carb coffee cake, but it’s most definitely worth the effort! Let’s start by preheating your oven to 325F.
Add the almond flour, oat fiber, baking powder and salt to a bowl and whisk them to combine.
In a separate bowl, mix together the eggs, sour cream, heavy cream, swerve and vanilla using a hand mixer. Then, add in the dry ingredients and mix just until combined. You don’t want to over-mix the batter.
Take the reserved 1/3 cup of the batter and mix in the cinnamon and 2 teaspoons of Swerve confectioners.
Take the sweet cinnamon mixture and dollop evenly all over the top of the cake. This next step is easy and actually makes it look really pretty!
Using a butter knife, holding it upright, swirl the cinnamon mixture into the cake batter.
How to Make the Crumble Topping
There is something about this topping that is so wonderful! The texture is just spot on, very much like a classic crumble topping, but without all the carbs and sugar! So let’s take the almond flour, walnuts, cinnamon, nutmeg and Swerve and add it into a mixing bowl, then mix it together.
Then pour the melted butter over the top and mix until well combined and it comes together. Crumble the topping over the top of the cake, making sure to evenly distribute it.
Then 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 40-45 minutes or a toothpick, when inserted, comes out clean and the crumb topping is golden. Let it cool down a bit before cutting into it. It doesn’t have to completely cool, but letting it to cool a little, allows the topping to firm up a bit.
Mine took exactly 45 minutes. Store leftovers in the fridge for several days or freeze.
Tips for Making the Best Keto Coffee Cake
HOW TO MAKE THE BEST KETO COFFEE CAKE
Texture is key in making a Low Carb cake recipe. Too many come out dry or with a “diet food texture.” But not your recipes! You are about to know the secret.
Using a mix of both Almond Flour and Oat Fiber will give you that authentic coffee cake texture that you’re looking for. Super fine almond flour works best in any kind of Low Carb or Gluten-Free desserts that don’t use all purpose flour in.
If you don’t have a super fine almond flour, you can certainly use what you have, just be sure to whisk the dry ingredients to break up any lumps.
WHAT IS OAT FIBER? IS OAT FIBER KETO FRIENDLY?
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.
The Oat Fiber is really important in this recipe! I use it in so many Keto dessert recipes, because of the amazing texture it gives whatever I am baking! It is hands down, the best ingredient I’ve baked with.
I use Lifesource Foods Oat Fiber 500, because they grind it to a very fine powder and has a mild flavor. The bag lasts a while, because you don’t need to use very much in your recipes.
WHAT Other Low Carb DESSERTS CAN YOU MAKE WITH OAT FIBER?
Here are just some of the many desserts that you can make using oat fiber:
WHAT SWEETENER IS BEST FOR KETO BAKING?
Swerve Confectioners has the best balance for Low Carb dessert recipes. Brown Swerve is great to use in recipes that would normally use brown sugar. Brown Swerve tastes, smells and feels just like brown sugar! Swerve, really did a great job with their sweeteners!
If you can’t get Swerve confectioners or Brown Swerve where you are, you can certainly substitute with another brand that you do have access to. If you can’t get confectioners, no worries, you can grind the granular to a fine powder using a coffee grinder and voila, there you have it! It really is the best sweetener to use in sugar free cake recipes.
