How to Make Slime-Filled Halloween Cookies
Step 1: Prepare the Cookie Dough
Begin by creaming softened butter and sugar together in a large bowl until light and fluffy. Add the eggs and vanilla extract next, mixing well until combined. In a separate bowl, whisk together flour and baking powder, then gradually incorporate it into your wet ingredients to form a soft dough.
Step 2: Make the Slime Filling
In a small bowl, combine powdered sugar, clear corn syrup, and a splash of water. Stir until smooth, then add gel food coloring to reach your desired slime color. The mixture should be thick yet pourable, perfect for oozing inside the cookies.
Step 3: Shape the Cookies
Divide the dough into small balls. Flatten each ball slightly, then create an indentation in the center to hold the slime filling. Spoon a small amount of the slime mixture into these indentations, being careful not to overfill.
Step 4: Seal and Bake
Take another small piece of dough to cover the slime on each cookie, gently sealing around the edges to enclose the gooey center. Place the cookies on a lined baking sheet and bake at 350°F (175°C) for about 12-15 minutes, until the edges are golden but the slime remains intact inside.
Step 5: Cool and Enjoy
Let the cookies cool on the baking sheet for 10 minutes before transferring to a wire rack. This helps the slime center set slightly but remain delightfully stretchy for the perfect Halloween surprise.
Pro Tips for Making Slime-Filled Halloween Cookies
- Chill the Dough: Cooling the dough for 15 minutes before shaping helps prevent the slime from leaking during baking.
- Use Gel Coloring: Gel food colors give more vibrant slime hues without thinning out the mixture.
- Don’t Overfill: Just a teaspoon of slime per cookie ensures a cute ooze without messy spills.
- Seal Well: Press edges firmly to trap the slime overflowing and maintain cookie shape.
- Cool Properly: Allow sufficient cooling time to avoid burns and keep the slime stretchy instead of liquid.
How to Serve Slime-Filled Halloween Cookies

Make Ahead and Storage
Storing Leftovers
Store cookies in an airtight container at room temperature for up to 3 days to keep the slime gooey and the cookie base soft and fresh.
Freezing
You can freeze unbaked slime-filled cookies by sealing them individually on a baking tray, then transferring to a freezer bag; bake from frozen with a couple of extra minutes in the oven.
Reheating
Warm your cookies in a low oven or microwave briefly to revive the stretchy slime center without melting it completely, perfect for reviving that oozy effect.
