Flourless Clementine Almond Cake Recipe
Adapted from a recipe by Nigella Lawson

Ingredients
4 clementines (about 13 oz)
6 large eggs
1/2 cup erythritol + 1/2 cup granulated Splenda (OR) 1 cup granulated white sugar
2 1/4 cups of ground almond meal (or 9oz of almonds finely ground)
2 teaspoons pure almond extract
1/2 teaspoon kosher salt
1 heaping teaspoon baking powder

Directions
Place the clementines in a pot and cover with water. Bring to a boil and let simmer 1 1/2 hours, until very tender. Remove from water, then chop and remove seeds. Add the remaining boiled clementine (everything but the pits) to a food processor or blender and puree until smooth.

Preheat oven to 350 degrees. Butter and line a springform baking pan (this is a sticky cake; you NEED a springform pan).

In a mixer with a whisk attachment, beat the eggs for 5 minutes until very light and frothy. Add the sweetener or sugar, ground almonds, almond extract, salt, and baking powder and beat again for 5 more minutes until very light. Pour into the prepared baking pan and bake 50 minutes to 1 hour or until set. Let cool in the pan, then unmold and serve.
Low Carb Note: Using the mix of sweeteners that I used, the cake works out to about 9g of net carbs per serving, which is fantastic. (The cake has 10 servings.)
