Hi Gwynn,
I can’t wait to make these but I have a couple of questions first. Have you tried making these in a 9*13 pan? I would prefer to use that if possible. Second, the last step on applying the topping, I am assuming you melt the hot fudge topping and the remaining 2 tablespoons of peanut butter fore drizzling. I am going to be making these in a couple of weeks and I will let you know how they turned out.
Thank you so much!
Hi Randy, I have not tried to make this recipe in a 9 x 13 pan. You will get a much thinner brownie when you change to a larger size pan. If you are fine with that then I would also recommend reducing the baking time by at least 5 minutes. For this recipe I actually put the hot fudge topping and peanut butter in disposable pastry bags and drizzled them that way without having to melt them. You can also use a plastic ziplock bag and snip off a corner to easily drizzle. The other option would be, as you mention, to heat the fudge and peanut butter so they loosen up a bit and are easier to drizzle. Hope all of that helps! Looking forward to hearing how your brownies turn out. And thank you so much for stopping by Swirls Randy! Happy baking, Gwynn
