How to Make Gluten Free Chocolate Cake

To Make the Keto Cake

Preheat oven to 350°F.

Add the almond flour, oat fiber, cocoa powder, baking powder and salt to a mixing bowl.

Whisk until well combined.

In a separate bowl, add in the egg whites and beat using a hand mixer to stiff peaks, then set aside.

In another bowl, add in the egg yolks, butter, monk fruit/allulose, sour cream, heavy cream, coffee mixture and vanilla.  Mix until well combined.

Fold in the egg whites and mix until they are combined.  Then mix in the dry ingredients and mix just until combined, without over-mixing.

Pour the batter evenly into two 9” nonstick cake pans that are lined with parchment paper rounds and sprayed with nonstick spray.  Be sure to also spray the sides of the pan.

Bake for 25-30 minutes or until a toothpick, when inserted, comes out clean. Allow to cool completely before frosting.

To Make the Sugar-Free Ganache Frosting

While the cakes are baking, add the chocolate chips to a mixing bowl.

Heat up the heavy cream, just until tiny bubbles start to form around the edges of the pot.  Pour the hot heavy cream over the chocolate chips and allow to sit for 5 minutes.

Whisk the chocolate/heavy cream mixture until you get a thick rick ganache.  Allow to cool at room temperature for about 20 minutes.

Using a hand mixer, mix in the mascarpone cheese and monk fruit/allulose until combined. Allow to sit at room temperature while the cakes cool.

Once the cakes have cooled completely, add the first cake upside down (flat side up) onto a cake stand or plate. 

A little tip for keeping the cake stand clean: take 1/2 parchment sheet and cut it into 4 strips, then place them halfway under each side of the cake. Take 1/3 of the frosting and spread it over the top using an offset spatula.

Take the second cake and add it over the top flat sound down this time.

Take another 1/3 of the frosting and spread it over the top.  Finally, take the remaining frosting and frost the sides of the cake and serve. I made some chocolate shavings using a Lily’s chocolate bar and a peeler to decorate the top.

Can I Freeze Almond Flour Chocolate Cake?

If you’re wanting to make this Keto cake in advance, you can always make it and freeze it until you need it.

To do so, set the entire assembled cake uncovered on a sheet pan and place it on an even surface in the freezer. Allow it to freeze like that for about 2 hours, then just remove it from the freezer and wrap tightly in a couple of layers of plastic wrap followed by a final layer of foil.

To freeze leftover slices of chocolate cake, you will follow these exact steps except the slices will only need to freeze for about an hour before wrapping.

Be sure to remove the plastic wrap prior to thawing the cake in the fridge.

Can I Eat Cake on Keto?

Almond flour chocolate cake is not only low carb it’s also healthy! Almond flour has many vitamins and minerals, especially vitamin E and magnesium.

That’s not to say you can’t have too much of a good thing. As with any sweet treat, even sugar free ones, you should eat them in moderation.

Tips for Making the Perfect Keto Chocolate Cake

• Allow it to Completely Cool: When you see just how scrumptious the cake smells while it’s baking, you may be in a rush to get it frosted. But chocolate cake layers made with almond is delicate and will need to be cool completely before you try and transfer them to a cake plate for frosting to ensure they do not crumble.

• How to Store Chocolate Cake: You’ll want to keep this low carb chocolate cake with chocolate frosting in the fridge to ensure it stays fresh. Store it in a cake keeper or other air tight container for up to a week.

• Best Sweetener for Sugar Free Ganache: Everyone has their favorite sugar substitute. And depending on the recipe, some may work better than others. For this recipe, you really want a good quality sweetener that doesn’t have a strange aftertaste. I have found that this Wholesome Yum’s Besti Monk Fruit/Allulose is a superb blend that makes fantastic tasting cakes and frostings without the cooling effect some other sugar substitutes have.

• Best Flour for Gluten Free Chocolate Cake: For this recipe, I also used Wholesome Yum’s Besti Super Fine Almond Flour and really love it!. It’s got such a nice mild flavor and perfect texture. Use code: KCC10 to save 10%.
