what kind of frosting works best

Readers like you enjoy the rich buttercream taste and minimal ingredients of our vanilla buttercream frosting.

For the best success we suggest mixing this frosting and allowing it to thicken in the refrigerator for 20 minutes. Then transfer it to a piping bag. For this recipe you want the frosting to be thick so it maintains the round piping form.

This frosting can be prepped days ahead of time and refrigerated. To use after it's been refrigerated, allow the frosting to set at room temperature for 20 minutes, then whip with a handheld mixer until light and fluffy.

If the frosting becomes "soft" in the piping bag, place the bag and tip in the refrigerator for 10 minutes to thicken and then resume decorating.

Lastly if you're a total chocolate lover, frost the brownie cookies with our Chocolate Buttercream frosting recipe for an extra chocolate boost.

are Oreo cookies gluten and dairy free

There are several cookies and cream style cookies available on the grocery store shelves. For this recipe you only need 6 cookies to create the yummy oreo taste. We've included links to 3 of the most popular brands among our readers.

First, Oreo released a gluten and dairy free cookie in 2021. It's been difficult to nail down their allergen statement;, however, there has been concern from readers that there is possible cross-contamination in the manufacturing process. These cookies do contain soy.

Next, the Kinnikinnick KinniToos are manufactured in a dedicated gluten and dairy free facility. And they are available to purchase here. Tap here to view their manufacturing processes.

And another oreo cookie brand readers enjoy is Glutino Chocolate and Vanilla Cream Cookies. They are certified gluten free and manufactured in a gluten free facility; however, there is the possibility of cross-contamination with dairy during the manufacturing process.

how do we store these cookies

Once decorated these cookies are best when stored in an airtight container up to a week in the refrigerator. We recommend serving the cookies out of direct sunlight.
