I'm making a cookie monster cake for my brother. He's a diabetic. What is the best thing to use instead of sugar for both the cake and the buttercream icing?

Sadly, there is no such thing as a diabetic friendly cake or frosting. You can use Splenda for baking, but it still has a nasty after taste. The problem is that our bodies convert carbohydrates into sugar, so most diabetics have to watch not only their sugar intake, but carb intake as well. I don't know of any sugar substitute for icing, since icing is essentially sugar. You could try a low carb cake that uses almond or coconut flour to help cut down on the carb count. Maybe someone on here has a tried and true low carb recipe? Otherwise, depending on what he can have don't be discouraged if he can only have a sliver. Good luck!

I don't have a low carb cake....but I do use this icing from time to time.

1 small box sugar free instant pudding, any flavor ( if using chocolate, sift 2 tablespoons of cocoa powder into the pudding mix)

1/2 cup skim milk

8 ounces cream cheese, room temperature

8 ounces sugar free Cool Whip

1 teaspoon vanilla

Combine cream cheese and pudding mix in mixer bowl and beat until smooth.

Mix in milk and vanilla until smooth.

Fold in Cool Whip.

Frost cake, store in the refrigerator.
