Since May is Celiac Disease Awareness month, I decided to make an awesome dessert featuring two of my favorite gluten free products. That dessert? These amazing gluten free oatmeal sandwich cookies! While my husband doesn’t have Celiac Disease and is only gluten intolerant, I know many of you do and I want you to know that I am so happy to be here sharing recipes and helping you along in your journey.
I was going to call these oatmeal cream pies but I decided on Oatmeal Sandwich Cookies because they’re really not a true copycat of the store-bought variety you are used to. The oatmeal cookie is adapted from my Oatmeal Raisinete Cookies and they’re a sturdier, thicker cookie than you would have in an oatmeal cream pie.
The two Bob’s Red Mill products I used in these oatmeal sandwich cookies today are their Gluten Free 1:1 Baking Flour and their Gluten Free Old Fashioned Oats. Both of these have been featured before, I almost always use the 1:1 blend in my cookies and most recently, I used it to make my Gluten Free Lemon Squares. Their old fashioned oats are the main ingredient in my oatmeal smoothies and overnight oats.
If you’re new to eating gluten free, be sure to check out my favorite gluten free pantry staples. I give an in-depth look at the products I use in my kitchen and which ones I prefer for baking. There are many Bob’s Red Mill products featured there because I truly love their gluten free products.
But lets get down to these cookies. They’re amazing! The cookies themselves have such great flavor, they even get two thumbs up from my chocolate peanut butter loving husband. Usually, if it doesn’t have chocolate or peanut butter, they’re not a winner in his eyes. He made an exception for these because they’re just that good!
The frosting really makes them too. I just used my regular vanilla buttercream frosting that I used in my gingerbread sandwich cookies. It’s nice and sweet and pairs so nicely with the cinnamon in the cookies. Plus, it’s such an easy frosting recipe, one that you’ll want to use as your usual vanilla buttercream.
You guys are going to love these cookies! Enjoy!
