Step 1.  Preheat oven to 375 degrees F and grease a round 9-inch cake pan.

Step 2.  For the shortcake, mix together Carbquik, water, cream, melted butter, and 6 tablespoons sweetener in a large bowl.  The batter will be very thick.

Step 3.  Add batter to pan and smooth the batter down equally with your hands.  Sprinkle 1 tablespoon of sweetener on top.

Step 4.  Bake for 20-25 minutes until browned on top and a toothpick in the middle comes out clean.

Step 5.  For the berry topping, add 1/3 cup blueberries, vanilla syrup, 1 tablespoon sweetener, and water to a blender and blend for 1 minute.  Mix liquid with the rest of the berries and set aside until needed.

Step 6.  For the whipped cream, mix together cream and powdered sweetener in a large mixing bowl.  Whip with an electric mixer until stiff peaks form.  

Step 7.  Once shortcake is done baking, allow to cool in the pan for 15 minutes before serving.  Serve each slice topped with berries and whipped cream.
