How to use glucose in cake recipe?

Hello! I'm trying to modify a moist chocolate cake recipe because it's not quite moist enough for me. Someone suggested brushing the cake with simple syrup (sugar dissoloved in hot water) but it made the cake a lot sweeter than what I was hoping for. (I'm trying to duplicate a recipe of my favorite moist chocolate cake sold at a nearby bakery.) I'm wondering if glucose would do the trick.





Here's the recipe:


2.5 cups all-purpose flour, 2 tsp baking powder, 1.5 tsp baking soda, 3/4 tsp salt


1 2/3 cups cold water, 1 cup unsweetened cocoa powder, 1 tsp vanilla extract, 1 cup butter, 2.5 cups granulated sugar, 4 whole eggs

I heard that if you add sour cream it will make cakes more moist.





Applesauce is another ingredient used to make it moist.





I found one site says to add a box of Jello (not sugar free) or 2 to the cake recipe.
