I think you’d be hard-pressed to find a homemade recipe that will get you closer in taste to an OREO cookie than this one. Both the cookie wafer and the vanilla cream filling taste identical to what I recall an OREO tasting like. They smell just like OREOs too!
The cookie wafer dough is really easy but you do have to roll it out, freeze it, and cut the cookies out with a cookie-cutter. This takes some time and the dough sticks like crazy, so be sure to use a lot of flour.
The MSBH has a recipe for both vanilla cream filling and chocolate cream filling. I opted to just make the vanilla cream filling, although I plan to try the chocolate sometime in the future. The vanilla filling is made with a combination of butter, vegetable shortening, sugar and vanilla. It whips up very light and fluffy.
The filling is simply smeared onto the bottom of one cookie wafer.
And then you make the sandwiches with another wafer cookie. Pretty simple. The wafers are quite crisp and the filling is quite soft at this point, so biting into the cookie is a little messy.
I found that putting the assembled cookies in a container and then leaving a little crack open in the lid, and then placing the container in the refrigerator overnight allowed the filling to firm up a bit and the cookies to soften a bit. Then, when you take a bite the filling doesn’t smoosh out and the cookie doesn’t break into pieces. And it still tastes just like an OREO cookie!
