I've been making these dessert snacks for years. The last 2 times I've baked them, the sugar has come out gritty and the butter seems all absorbed. Very dry. My recipe calls for brown sugar, butter, and (added pecans after the boiling).
After boiling on the stove for 2 minutes this is poured onto graham crackers in a greased pan. Then it's baked at 350 degrees for 10 min. When I take them out it seems all moisture has been sucked out and everything falls apart and sugar is gritty.
I'm using a Convection oven, but I have done all of this the same way for almost 40 years and don't know what's going on.
