These are soft and slightly chewy with a light peanut butter topping. My mom always made these when we were little.
The recipe is a favorite of mine with one exception. This recipe is only 2/3 of my recipe, which is the reason why everyone is having trouble filling a 13x9 inch pan. My recipe calls for 3/4 c. butter, 3/4 c. sugar, 3/4 c. brown sugar, 1 egg, 2/3 c. pb, 3/4 tsp baking soda, 1/2 tsp salt, 1 tsp vanilla, 1 1/2 c oats, 1 1/2 c flower and 1 1/2 c chocolate chips. The frosting is the same though. Also, my recipe only bakes for 12 minutes. Half the time. They are delicious this way. They aren't undercooked. They are chewy and perfect. My friend at work says she doesn't even like peanut butter, but loved these. - 28 Mar 2010 (Review from Allrecipes US | Canada)
A tasty treat. All turned out as expected, sweet and chewy/crunchy, except this really doesn't fill a 9 x 13" pan. A slightly smaller pan might be good, if you have some weird size (9x9 or 8x8 would be a bit too small), or else fill about 2/3 of 9x13, which bakes fine in 20 minutes. I used margarine because I was out of butter, but otherwise followed recipe exactly. The drizzle is tasty and not too sweet - do make it! - 29 Aug 2006 (Review from Allrecipes US | Canada)
I have made this so many times and it never lasts in my house for long. These are a favorite at my house. - 03 Oct 2007 (Review from Allrecipes US | Canada)
