N.i.P.s...anyone can answer

Ok so nips are these little snacks you make using about a gram, you take 4 saltine crackers some Nutella spread or Peanut butter. Spread each cracker witth a glob of nutella, put .5 on two of the crackers and take the remaining crackers and put em on top like a sandwhich. Make sure no bud is poking out and make sure it is smothered in the Nutella. Then you put em in the oven for about 325 degrees F for 25 mins. Thats pretty much the recipe and thats for one gram.

Question: Im probably scarfin down 2 grams of this shit and my girlfriend is doing it for her first time so she is only going to do 1 gram. Ive done it b4 and know how to make them, its just that im wondering if i have to turn the heat up or do i keep them in longer since i am using 3 grams now instead of the original recipe that recalls for one gram????/??????

See the thing is, im going to make about 6 little sandwhiches(2 for my girl and 4 for me)...i was just thinking because you know when you add more than one item in the microwave you have to turn up the heat or keep it in longer so they can cook evenly, but i dont know if this concept is the same for the oven...Do you guys get me?
