These cauldron cookies are a playful way to celebrate Halloween. Baked as chocolate cookie cups and filled with colorful buttercream, they become bubbling little cauldrons topped with sprinkles, candy eyes, and pretzel stick stirrers. They are simple to make, fun to decorate, and always a hit with both kids and adults.
I first made these with my nieces on a rainy October afternoon, and they could not stop laughing while decorating their own cauldrons. Now it has become a tradition we look forward to every year.

Step-by-Step Instructions
- Prepare the pans:
- Preheat the oven to 350°F and lightly grease three 12 cup mini muffin pans. This prevents sticking and ensures even browning.
- Mix the dough:
- Combine cake mix eggs oil and optional food coloring in a bowl. Stir until fully blended without dry patches. The dough will be thick but manageable.
- Shape and bake:
- Scoop about half a tablespoon of dough into each muffin cup. Flatten gently with your fingers to prevent doming. Bake 8 to 10 minutes until edges are set but centers still soft.
- Indent and cool:
- While warm press a one tablespoon measuring spoon into the center of each cookie to form a well. Allow them to cool in the pan before transferring to a rack.
- Make the buttercream:
- Beat softened butter until fluffy. Gradually add powdered sugar vanilla and salt. Add milk one tablespoon at a time until smooth and pipeable. Tint with green coloring until you reach the shade you like.
- Fill and decorate:
- Pipe the green buttercream into the cooled cups filling them to look like bubbling potion. Top with sprinkles candy eyes and broken pretzel sticks for a playful cauldron look.

The buttercream is my favorite part because it carries the decorations beautifully. I still remember my son proudly showing off his cauldron with three candy eyeballs as if he had brewed his own monster potion.

Keep decorated cookies in an airtight container for up to four days. Store in the fridge for a week or freeze the undecorated cookie cups for three months. Thaw at room temperature before decorating.
Ingredient Substitutions
Try a brownie base instead of cake mix for a fudgier result. Swap buttercream with cream cheese frosting for tang or use white chocolate ganache tinted green for extra richness.
