My little man and I did some baking this weekend. I was actually a little taken back by his ambition to bake. He wanted cookies and he helped me every step of the way. He actually helped me a little too much…
First, we made cookie dough and baked the cookie part of these bars. Then, I let the pan sit there while it cooled completely and laid out some of the ingredients for frosting. I was letting butter get to room temperature and pulled out a bag of powder sugar. While everything was cooling (and warming up), I decided to go fold some laundry and take a shower. I came back into the kitchen about an hour later and noticed that butter and sugar were missing. Dun dun duuuun….
I looked around, I asked hubs, and nothing, it was just gone. Then, I looked over at the counter where the cookie bar base was cooling and noticed powder sugar around my mixer. I looked into the mixer and sure enough, butter was in the mixer, somewhat mixed with powder sugar and an empty sugar bag next to it. Oy!
Apparently, little man took it upon himself to make the frosting. Luckily, this moment was considered adorable because I had just enough powder sugar left in the bag to use for this recipe so the ingredients were not wasted. The only thing is, I had to beat the heck out of the butter because there is a reason why you should cream butter first and sift in powder sugar…lumps. But all was good because frosting was extra smooth and silky.

I could take a triple bar right now. I’ve been on go all day and those look like they would give me that added flavor boost. Great pictures and I love the combination of ingredients.

Would these be easily adapted to sandwich cookies?

Hi Leigh,
Do you mean whoopie pies? If so, they have a cake-like texture and these cookies are pretty similar to a typical chocolate chip cookie. You can make individual cookies by just rolling the dough into 1-inch balls and baking them for about 9-11 minutes. You can always put two of those cookies together like a sandwich (just make sure they are cooled first). I’m just not sure if you want the end result to be like a whoopie pie or not.

Hi! I just made these for a ladies bookclub luncheon dessert. They smelled wonderful baking and are just finishing cooling so I can frost them. I noticed you have 1 tsp of vanilla in frosting ingredients but in the instructions for making the frosting it doesn’t say when to add it! I added in with the maple syrup. I kind of wish I hadn’t as I taste the vanilla more than the maple but maybe not when eaten as a frosted bar! I’m sure they will be yummy but wanted to tell you about the missing step!

Hi Kym! Thank you so much for letting me know. I add vanilla at the same time as well but if you don’t feel like adding it, you can skip it all together. I hope everyone enjoyed the cookie bars and thank you for letting me know that I was missing the step 🙂
