Passover Chocolate Truffle Cake

Passover chocolate truffle cake

Passover is less than three weeks away (yikes) so you’re probably planning your holiday meals.

This recipe isn’t what I’d call easy, but it’s really yummy and it’s gluten free. You can kid yourself that it’s good for you because it’s made with sweet potatoes – which you can’t really taste, but which help make it lighter than most flourless chocolate cakes.

You can gussy it up more than I did in this photo by garnishing with berries and/or whipped topping.

Ingredients:

16 oz. semisweet chocolate, divided
1½ cups baked mashed sweet potatoes at room temperature (or use canned sweet potatoes)
1/3 cup plus ¼ cup sugar
1 Tbs. vanilla sugar or 1 tsp. vanilla extract
4 oz. very soft unsalted butter or margarine
6 large eggs, separated
¼ tsp. salt

Directions:

Preheat oven to 350 degrees.

Line a 9-inch spring form pan with parchment paper.

Melt 10 oz. of the chocolate in the top of a double boiler and let cool.

Using a wire whisk, blend together the mashed sweet potatoes with 1/3 cup of sugar, the vanilla sugar or vanilla and the softened butter until well blended.

Stir in the egg hyolks and then the melted chocolate, mixing to blend.

In a clean, dry bowl, whip the egg whites with an electric mixer, starting on low speed. When the egg whites are foamy, add the salt and whip on high speed, slowly dusting in the remaining ¼ cup sugar. Beat until stiff, glossy peaks form.

Fold 1/3 of the egg whites into the sweet potato mixture and work in to lighten the batter. Then gently fold in the remaining 2/3 of the egg whites, blending well but taking care not to deflate the mixture.

Spoon into the prepared pan and bake for about 40 minutes. The cake will rise somewhat, look dry, and have a slight crack on top. The middle should be soft but firm.

Cool in the pan for about 20 minutes, then remove the sides from the pan and cool on a wire rack. Chill for at least an hour.

Make the ganache glaze: Chop the remaining 6 oz. of chocolate. Bring ¼ cup of water to a gentle boil and add the chocolate all at once. Remove from heat and stir briskly with a wire whisk until all the chocolate melts and is a thick sauce-like consistency. Refrigerate for an hour.

Invert the cake onto a platter so the flat bottom faces up. Pour the glaze over the cake, using a spatula to even it out and spread along the sides.

Serves 8 to 10
