Preheat oven to 350℉, and set a rack to the middle of the oven. Butter an 8 X 8 square, baking pan.
In a large mixing bowl, combine the Keto Chow, almond flour, coconut flour, ginger, baking powder, cinnamon, and salt and set aside.
In a separate bowl, whisk the eggs, then whisk in the melted butter, erythritol, allulose, yacón syrup, almond milk, and vanilla extract.
Pour the wet ingredients into the dry ingredients and mix until fully combined.
Spread batter in the prepared cake pan and bake for 35-40 minutes until the cake is brown, set around the edges, and the center springs back when gently touched.
While the cake is baking, make the Chantilly cream by combining the heavy cream, powdered erythritol, and vanilla extract in a chilled mixing bowl. Beat with an electric mixer until the cream holds soft peaks. Refrigerate until ready to use.
Cool the cake and remove it from the pan. Dust it with a sprinkling of powdered sugar. For an old-fashioned decorative touch, you can cover the cake with a doily and sift the powdered erythritol over it. Carefully lift the doily and the powdered erythritol will create a lacy pattern.
Serve the cake at room temperature or slightly warm with a healthy dollop of the Chantilly cream.
Notes
*The yacón syrup adds a molasses-like flavor to the cake but can be omitted.
