Cookie Dough
- 2 ½ cups All-Purpose Flour
- 1 cup Butter, softened
- ½ cup Granulated Sugar
- ½ cup Brown Sugar, packed
- 2 Eggs
- 1 teaspoon Baking Soda
- 1 teaspoon Vanilla Extract
Slime Filling
- ¾ cup Fruit Jam or Jelly (raspberry, blackberry, or mango recommended)
- 1 tablespoon Cornstarch
- Gel Food Coloring (green, purple, or desired slime color)
- Prepare the Dough: Start by creaming the softened butter with both granulated and brown sugars until light and fluffy. Beat in the eggs one at a time, then stir in the vanilla extract. In a separate bowl, whisk together the all-purpose flour and baking soda. Gradually add the dry ingredients to the wet mixture, stirring until a soft dough forms.
- Make the Slime Filling: In a small saucepan, gently warm your chosen fruit jam combined with cornstarch to thicken it slightly. Add a few drops of gel food coloring to create the vivid slime effect. Stir constantly over low heat until the mixture thickens and becomes smooth. Remove from heat and let it cool completely to hold its shape during baking.
- Assemble the Cookies: Preheat the oven to 350°F (175°C). Roll the dough into small balls and flatten each into a disc shape. Spoon a small amount of the cooled slime filling onto one disc, then cover with another dough disc. Pinch the edges tightly together to seal completely, preventing leakage during baking.
- Bake and Cool: Place the sealed cookies on a parchment-lined baking sheet. Bake for 10 to 12 minutes or until the edges are golden, but the centers remain soft. Remove from the oven and allow the cookies to cool fully on a wire rack. The slime center will set into a gooey consistency as the cookies cool.
Notes
- Seal Tight: Press cookie edges firmly to prevent slime leakage during baking.
- Chill Dough: Refrigerate assembled cookies for 20 minutes before baking to help maintain their shape.
- Use Gel Colors: Gel food coloring provides vivid colors without affecting dough consistency.
- Thicken Filling: Cornstarch is essential to keep the slime filling gooey yet stable.
- Watch Baking Time: Slightly underbake for gooier centers but avoid undercooking the dough.
