Prepare the strawberry jelly: Add the jelly to a heat-safe bowl or pot. Melt the strawberry jelly in the microwave or a pot on the stove. Set aside to cool.
Assemble the brain frosting: Beat the butter, powdered sugar, milk, and vanilla together with an electric whisk or stand mixer until smooth and thick. Add in a few drops of red food coloring to get a pale pink colored frosting. Add the frosting to a piping bag with a ¼-inch round tip (such as Wilton #10).
Frost brains onto the cookies: Take your Oreo and pipe a thin layer of frosting over the top, then smooth it with your butter knife.
Piping: Next, you'll need to simply pipe a line of frosting down the middle of the oreo. Then, on each side of the line, pipe a squiggly line back and forth to fill the side. Repeat with the other side. Repeat with the remaining cookies and frosting.
Set and add jelly: Place the cookies onto a cookie sheet and place in the fridge for 15 minutes for the frosting to set. Gently brush the cool melted raspberry jelly over the set frosting. Enjoy!
If you don't have a piping bag, you can use a zip-top bag with the corner snipped off.
Ensure your melted strawberry jelly is cooled, as you don't want it to melt the frosting. It just needs to be easy to brush. Instead of heating it, you could give it a really good stir.
If your frosting is too thick, you can add a little more milk and then beat it until your desired consistency is reached. If the frosting is too thin, you just need to add a little more powdered sugar and beat it again until the desired consistency is reached.
When using food coloring, a little goes a long way. To achieve a pink color, start with a few drops and then add more as needed until the desired color is reached.
If you don't have raspberry jelly, you can use any other red fruit jelly or jam (but strain out any chunks).
