Oatmeal Whoopie Pies with Brown Butter-Maple Frosting

Fall brings out the baker in me.  Or it is just a good excuse to be baking.

In all honestly I love to bake.  It relaxes me.  Getting my hands in the dough, stirring up a batter and making something sweet to share with people close to me is so rewarding.  

I had the idea for this recipe when Mr. Mother Thyme was enjoying a warm bowl of oatmeal with maple and brown sugar.  That is when the light bulb went off that combining all these flavors in a fabulous little cookie would be a sweet treat.    

I incorporate pure maple syrup in the cookies and then sandwich them not only with brown butter but with more maple syrup to create this incredible brown butter-maple frosting.  All I can say is wow!  If just a brown butter frosting wasn’t going to be good enough, right?   I thank the constant wheels that are turning in my head for coming up with this combination.  

You will need to restrain yourself from eating just the frosting, unless of course you don’t want to add it to the cookies.

Mr. Mother Thyme is always disappointed when I make these to give away.  I guess it’s just another excuse to make more!
