Q: Can I use in between layers of cake?

I would think so as long as the cake is cooled. Thanks for stopping by

Q: Does it has gelatin ?

This is the list of ingredients that is located on the bottom of the item page: Ingredients : SUGAR, MODIFIED CORNSTARCH, CONTAINS LESS THAN 2% OF SODIUM PHOSPHATE, TETRASODIUM PYROPHOSPHATE, SALT, MONO- AND DIGLYCERIDES, ARTIFICIAL COLOR, NATURAL AND ARTIFICIAL FLAVOR, YELLOW 5, YELLOW 6. So, no it does not say gelatin as an ingredient

Q: how many carbs are in a serving?

According to the package label, there are 4 servings per box, 25 calories and 5 grams of carbs per serving. If you are following a Low Carb diet like I have been for over 3 years, I mix the sugar-free Jell-O pudding mix with 2 cups HEAVY WHIPPING CREAM - whisk by hand for between 2-3 minutes, then store in a covered container in the refrigerator. I serve it as a daily dessert with a mix of fresh strawberries, blackberries and raspberries (all VERY low carb fruits). I usually end up getting 6 servings out of one box Jell-O/one container HEAVY whipping cream. Consistency of the mixed pudding is fairly dense, like cheesecake. I have also found that consistency varies depending on the brand of heavy whipping cream used. I prefer using SUNNY SELECT brand whipping cream - I get the stiffest consistency using Sunny Select. Some of the other heavy whipping cream brands result in a more pudding-like consistency. Tastes the same, but I prefer the more cheesecake consistency.
