These brownies are so good!! I like the crunch of the crust and the fact that they are not overly sweet. Of course DH wanted them sweeter/more chocolatey; so next time I may mix in some chocolate chips to the middle layer. Made for 123 Hits.

Well, where do I start... I chose this recipe because I had unsweetened chocolate squares in the pantry and jumped at the chance to use them. All other ingredients are pantry items. I was attempting to make it lactose-free so substituted vegan margarine for the unsalted butter and soy for the milk. I reduced the added salt where necessary. I realized though that even plain chocolate has "milk solids" added so if anyone has suggestions for finding pareve chocolate, I'm all ears.
The only thing I found frustrating was the 9x9 pan. I don't think that is very standard. I have 8x8 and 9x13 but felt those would both throw it off too much. Ended up doing 2 bread pans instead. They were 8.5 x 4.5 so only 4.5 inches lost. End result was thicker than necessary so I think 9x13 will work fine. Recipe yeild was 18 which seemed like alot but I cut 10 per pan and they were still large enough. Bonus that I will freeze one pan since we really don't need that many of these at once!
I did not add any extra sugar in spite of using unsweetened chocolate and it was sweet enough... especially with being frosted. Mixed feelings on the crust. It was like having one of those crunchy granola bars underneath. For home I think I would prefer it without but it did make it less messy to eat so could be a bonus for serving to a crowd.
5 stars for the frosting... I think it will be my chocolate frosting recipe from now on. Your recipe doesn't specify it so I'll mention for those unfamiliar with powdered sugar-- sifting is imperative!!

These are very tasty brownies. I never have had any with an oatmeal crust. My DH really enjoyed them. He said you can't go wrong with adding oatmeal to baked goods. My oldest son wasn't crazy about the oatmeal, though - go figure! LOL I didn't have unsalted butter so I used salted and they turned out better. One thing, though, is I just barely had enough chocolate frosting to cover. I would double the ingredients for the frosting next time. Thanks so much!
