    The only problem with these is that if I bake them while my boyfriend is there, he will eat them all and not give me a chance to try them haha. These look sooo yummy!

    I just wanted to leave a little note letting you know that I made these last weekend and they were wonderful! I used a smaller baking dish so my bars turned out about 3 times as thick as the ones in your picture (also lead to a cook time of nearly 40 minutes.) SO SO YUMMY! Thank you.

    tried these today but it had a very bad aftertaste… unfortunate since they looked so good! Not sure if i did something wrong because I thought I followed the instructions perfectly… I used yellow sugar instead of brown. Could that have been it?

    I normally love your recipes – your green chile enchiladas are a family favorite, and your orange dream cupcakes are delicious! But I had problems with this recipe, even though I followed the instructions exactly. At 20 minutes of baking time, the inside of the pan was still soupy. I had to bake them another 15 minutes before the toothpick came out clean, and at that point they had browned so much that they weren’t as pretty as yours. They still taste good, but I was disappointed in the appearance since I made them for a bake sale. Normally my oven bakes okay, so I don’t know what the problem was. Just wanted to give others a heads up that they may need to plan for a little extra baking time!

      Oh no! Did you line your pan with foil? That seems to really help evenly cook them. Also make sure your oven is all the way heated before sticking them in. Merry Christmas!

    I just made these about an hour ago. I too had to leave them in the oven for an additional 10 minutes. Overall they were delicious!

    Hi! I made these…but, mine were THICK. I used a 9×13 baking pan. Yours look thin. Which is one of the reasons, I tried this recipe. But, maybe next time I’ll use a bigger dish…b/c I would like them thin like your picture!

      Also, my baking time ended up being about 15 minutes longer b/c they were so thick! I’ll try a larger pan next time and see! :)

    Can you freeze these like you would cookies? Would they still be the same after defrosting?

        I’m confused about the amount of butter to use. You listed it as 1 and 1/2 cups butter but you also said 12 TB which is only 3/4 cup butter. If you are suggesting 1 and 1/2 cups of butter, then you mean 24 TB. Please advise. Thanks!

          Now I’m confused about the butter. How much? 1.5 cups? 0.5? Something else? Also, about how many bars does this make? I need about 4 dozen so I want to know how much to increase the recipe. Thanks!

            It is 1.5 cubes of butter or 12 TB of butter! Sorry for the confusion! :) They are made in a 13×9 baking sheet, so it depends how big you cut them! I usually get about 20 from this sheet!

    Would these freeze well? I am looking for a cookie recipe for a cookie exchange for work but they need to be freezable as we are exchanging a lot and a few weeks before christmas.
