Keto Texas Sheet Cake

When Swerve sent me a few box cakes to try, I figured it would be a decent product, as you all know I’m an avid baker and I use powdered erythritol as a sugar substitute to keep it low carb.

The first time I used a Swerve Box Cake, I actually used two boxes to make a double layer cake for a birthday. I made used both a chocolate cake and a vanilla cake to make a double layer cake with this sugar free chocolate frosting for a birthday and people loved it.

I’ve exchanged the chocolate cake recipe from scratch for a new and improved one. Let me know if you want the old recipe.Re: Xantan Gum: It’s not necessary. It does help to keep cake from being to crumbly, so I add a touch to my keto baked goods. You do not have to use it.
