    Why You'll Love This Recipe

    These Halloween Oreo Brain Cookies are easy to make and will be a hit with both kids and adults.

    The ingredients are simple and can be found in any grocery store.

    This fun Halloween treat is great for a party or as a fun holiday snack!

    This recipe uses a simple frosting recipe that's easy to assemble.

    Ingredients

    • Oreo Cookies - These creme sandwich cookies can be found in any grocery store in a variety of different flavors.
    • Raspberry Jelly - Once melted, jelly is used to brush over the set frosting to create a realistic brain aesthetic.

    For the brain frosting

    • Unsalted Butter - Makes up the base of the frosting, adding a thick texture and rich buttery flavor.
    • Confectioners Sugar - Used to sweeten up the frosting, which makes it thick and easy to pipe.
    • Milk - Thins out the frosting to the consistency you need while keeping it creamy.
    • Vanilla Extract - Adds a hint of vanilla flavor throughout the frosting.
    • Red Food Coloring - Added to create a pink color that is similar to the color of brains.

    Please see the recipe card below for quantities.

    Instructions

    Wondering how to make this Halloween Oreo Brain Cookies recipe? It's easy! Just follow this step-by-step photo tutorial. Then, scroll down for the recipe card for the full ingredients list and recipe method.

    Melting raspberry jelly slightly.

    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.

    Bowl of pink frosting.

    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). 

    Frosting the cookies.

    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 frosting with a line down the middle and squiggly lines on each side, to look like brains.

    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.

    Brushing the 'brain' frosted cookies with jelly.

    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!

    Top tips

    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).

    Variations

    Instead of oreo cookies, try using other types of cookies such as graham crackers, vanilla wafers, or even shortbread cookies.

    Try using other types of fruit jelly or preserves such as apricot, cherry, or blackberry.

    Use white frosting and add green food coloring for a fun ‘zombie brain’ look!

    Top the brains with edible glitter or sprinkles for a fun and festive touch.

    Storage

    Once the frosting on top of the cookies has been set, store them in a single even layer in an airtight container at room temperature. They will keep fresh for up to one week.

    FAQs

    Can these cookies be made ahead of time?

    Yes, these cookies can be made up to a day in advance. Store them in an airtight container at room temperature until ready to serve.

    Can I freeze these cookies?

    Freezing is not recommended as the cookies may become soggy.

    Can I use premade pink frosting?

    Yes, you can use premade pink frosting from a can. Simply pipe it onto the cookies using a piping bag fitted with a ¼-inch round tip.
