How to Make Purple Monster Chocolate Chip Cookies
Step 1: Preheat the Oven
Preheat your oven to 350°F.
Line two large baking sheets with parchment paper or silicone baking mats.
Step 2: Soften the Cookie Dough
Place the refrigerated chocolate chip cookie dough in a large mixing bowl.
Allow it to sit at room temperature for approximately 10 minutes, or until it is soft enough to mix.
Do not let the dough become overly warm.
Step 3: Add the Purple Coloring
Add a small amount of purple gel food coloring to the dough.
Mix with a sturdy spatula or clean hands until the color is evenly distributed.
Add more coloring one drop at a time until the dough reaches a bright purple shade. Gel coloring works better than liquid food coloring because it produces a stronger color without making the dough wet.
Step 4: Add the Mix-Ins
Reserve a few Oreo pieces and white chocolate chips for decorating the tops.
Gently fold the remaining chopped Oreos and white chocolate chips into the purple cookie dough.
Avoid overmixing, which can crush the cookies too finely and make the dough muddy in appearance.
Step 5: Shape the Cookies
Scoop approximately two tablespoons of dough for each cookie.
Roll the portions into balls and arrange them on the prepared baking sheets, leaving approximately two inches between each one.
Gently press a few reserved Oreo pieces and white chocolate chips into the surface of every dough ball.
Step 6: Bake
Bake the cookies for approximately 10–12 minutes.
The edges should be set, but the centers may still appear slightly soft. Avoid overbaking if you want chewy cookies.
Step 7: Add the Candy Eyes
Remove the baking sheet from the oven.
While the cookies are still warm, gently press two candy eyes into each cookie.
You can use eyes of different sizes or add one, two, or three eyes to create a variety of monsters.
Step 8: Cool
Allow the cookies to cool on the baking sheets for approximately five minutes.
Transfer them to a wire rack and let them cool completely before adding the mouths.
Step 9: Decorate the Monster Faces
Use black decorating gel to draw zigzag mouths, crooked smiles, stitches, or little fangs.
You can also use melted dark chocolate in a small piping bag.
Allow the decorations to set before stacking or storing the cookies.
Tips for the Best Monster Cookies
Use gel food coloring rather than liquid coloring. Gel creates a vibrant purple shade without changing the dough’s consistency.
Keep the dough cool. If it becomes soft or sticky after mixing, refrigerate it for approximately 20–30 minutes before shaping.
Press several Oreo pieces and white chocolate chips into the tops before baking so the mix-ins remain visible.
Add candy eyes immediately after baking. The warm cookie will hold them securely without melting them.
Remove the cookies while their centers still appear slightly underbaked. They will continue cooking on the hot baking sheet.
Wait until the cookies are completely cool before drawing the mouths, or the decorating gel may melt and spread.
Can I Use Homemade Cookie Dough?
Yes. Prepare your favorite chocolate chip cookie dough, then add purple gel coloring after combining the wet ingredients.
Fold the chocolate chips and Oreo pieces into the dough before chilling and baking.
A pale cookie dough works best because it allows the purple color to remain bright and visible.
Can I Use Liquid Food Coloring?
You can, but gel coloring is recommended.
Liquid coloring may require a larger quantity and can soften the dough. If the dough becomes sticky, refrigerate it before shaping.
How to Keep the Cookies Purple
Cookie dough naturally browns as it bakes, so the finished color may be slightly less vibrant than the raw dough.
For a stronger purple color:
- Use gel or paste food coloring
- Start with light-colored cookie dough
- Avoid overbaking
- Use parchment paper
- Bake one test cookie before adjusting the color
- Add a small amount of violet coloring rather than excessive blue and red
Decorating Ideas
Make every cookie look like a different monster by using:
- One large candy eye
- Several miniature candy eyes
- Zigzag chocolate mouths
- White chocolate fangs
- Mini marshmallow teeth
- Halloween sprinkles
- Mini Oreos
- Chocolate horns
- Black sugar crystals
- Edible glitter
The faces do not need to match. Uneven eyes and crooked mouths make the monsters more playful.

Stuffed Monster Cookies
Wrap each portion of purple dough around a miniature peanut butter cup, chocolate truffle, or Oreo.
Make sure the filling is completely enclosed before baking.
Can I Add Halloween Sprinkles?
Yes. Gently fold a few sprinkles into the dough or press them onto the surface before baking.
Avoid mixing them too aggressively because the colors may bleed into the purple dough.
Can I Prepare the Dough Ahead?
Yes. Prepare and shape the purple cookie dough up to 24 hours in advance.
Arrange the dough balls in an airtight container and refrigerate them. Bake directly from the refrigerator, adding one or two minutes to the baking time if necessary.
Wait until after baking to add the candy eyes and monster mouths.
Storage
Store the cooled cookies in an airtight container at room temperature for up to 4 days.
Place parchment paper between layers to protect the decorated faces.
If you use decorating gel that remains soft, arrange the cookies in a single layer whenever possible.
Can You Freeze Monster Cookies?
Yes. Freeze undecorated baked cookies in a freezer-safe container for up to 2 months.
Thaw them at room temperature, then add the candy eyes and monster faces.
You can also freeze shaped cookie dough balls for up to 2 months. Bake them from frozen, adding approximately two minutes to the baking time.
Frequently Asked Questions
Why did my cookies spread too much?
The dough may have become too warm. Chill it for 20–30 minutes before baking.
When should I add the candy eyes?
Add them immediately after removing the cookies from the oven so they stick to the warm surface.
Can I bake the candy eyes in the oven?
Some candy eyes can melt or discolor during baking. Adding them after baking produces the best appearance.
How do I keep the Oreos visible?
Reserve some chopped Oreo pieces and press them into the tops of the dough balls before baking.
Can I replace the white chocolate chips?
Yes. Use semisweet chocolate chips, milk chocolate chips, peanut butter chips, or colorful candy-coated chocolates.
Do I need to chill the dough?
Not always. Chill it if it feels sticky, warm, or difficult to shape.
Can children help make these cookies?
Yes. Children can press in the Oreo pieces, add candy eyes, and create different monster faces with adult supervision.
Can I make smaller cookies?
Yes. Use approximately one tablespoon of dough per cookie and reduce the baking time to about 8–10 minutes.
