Ingredients
- Devil's Food cake mix: provides a rich chocolate base choose a high quality brand for moist and flavorful results
- Large eggs: help bind the dough and add tenderness
- Canola or vegetable oil: keeps the cookies moist and soft avoid olive oil for flavor reasons
- Black food coloring (optional): deepens the cookie color to look more like a cauldron use gel coloring for vibrancy
- Unsalted butter: softened for creamy buttercream without overpowering saltiness
- Powdered sugar: sweetens and thickens the frosting for piping
- Vanilla extract: adds warmth and depth to the frosting flavor
- Salt: balances sweetness enhancing the overall taste
- Milk: controls the frosting consistency for smooth piping add slowly to avoid thinning too much
- Green food coloring: gives the frosting the signature bubbling potion hue gel coloring works best
- Round green sprinkles and Halloween sprinkles: provide texture and themed decoration
- Candy eyeballs: add a spooky and playful look for Halloween fun
- Pretzel sticks: broken in half to use as edible stir sticks adds a salty crunch contrast
Instructions
- Scoop the Dough:
- In a large bowl combine cake mix, eggs, and oil along with black food coloring if using. Beat or stir until the mixture is uniform and smooth
- Shape and Bake Cookies:
- Preheat the oven to 350 degrees Fahrenheit and grease three mini muffin pans using a light coating for easy cookie release. Scoop about half a tablespoon of dough into each muffin cup and flatten the dough lightly with your fingertips. Bake for eight to ten minutes until edges are set and the tops look dull not shiny
- Form the Cauldrons:
- Immediately after removing cookies from the oven press a tablespoon measuring spoon into the center of each cookie to create a small indentation. This indentation will hold the buttercream. Allow cookies to cool completely in the pans before frosting
- Make the Buttercream Frosting:
- In a medium bowl beat softened butter until creamy. Gradually add powdered sugar, vanilla extract, and salt mixing thoroughly between additions. Add milk in small amounts until frosting is smooth and can be piped easily. Add green food coloring a little at a time until the desired shade is reached
- Fill and Decorate:
- Use a piping bag or zip bag with a cut tip to fill each indentation with green buttercream topping them to look like bubbling potions. Decorate the tops with green and Halloween sprinkles along with candy eyeballs. Break pretzel sticks in half and stick one half into each cookie as a stir stick
- Arrange and Serve:
- Place the decorated cookies on a serving platter and enjoy immediately or store until party time

My favorite part of this recipe has to be the buttercream because it is so smooth and easy to color. I remember making these with family one year where my niece meticulously placed candy eyeballs and pretzel sticks that turned the cookies into real mini cauldrons
Storage Tips
Store leftover cookies in an airtight container at room temperature for up to two days or refrigerate if your kitchen is warm. Cooling the cookies completely before frosting helps prevent melting and sogginess. If you want to keep them longer bake the cookies and frost separately then assemble after thawing to keep the texture best
Ingredient Substitutions
You can swap the Devil's Food cake mix for a dark chocolate or red velvet mix if preferred just keep in mind this will alter the flavor profile. Buttercream can be made dairy free using coconut oil or vegan butter and powdered sugar just be sure to chill the frosting to firm up for piping. For an oil substitute try melted coconut oil though it may add a subtle flavor
