wow I just made these today, and they are definitely one of the best brownies I have ever had! Good thing the family is away on vacation so I can have these to myself! I


Dylan, your comment made my day, I am so happy that you took the time to tell me about the brownies, and I am happy that you got to enjoy them all to yourself :)



I just made these. The recipe says to use an 8 inch pan. Is this a mistake? Is it supposed to be a 13x9 inch pan? I used a 9 inch pan and it was barely big enough. Tastes delicious but seems like the pan is way too small.


Yes, sorry, a 9x13 pan is used.



Made these today and they’re great! Super fun and my fiancé loves them. Just wondering though, how is it that they can be stored at room temp? I’m new to baking anything that has a whipped topping. I’d love to keep it room temp but that seems odd to me. How is it that it doesn’t spoil?


Happy that you liked it, thanks for the feedback!
