How to Make Halloween Slime Cupcakes
Step 1: Preheat the Oven
Preheat your oven to 140C Fan/325F/Gas Mark 3. Line a cupcake tin with cupcake cases; black ones work best for this spooky theme.
Step 2: Prepare the Batter
- In a mixing bowl, combine the softened baking spread and caster sugar using an electric mixer. Beat them together for about five minutes until the mixture is smooth and fluffy.
- Add the eggs and vanilla extract into the mix. Whisk them well until fully combined.

- Bake in the preheated oven for 25–30 minutes or until a skewer inserted into the center comes out clean.
- Allow them to cool completely on a wire rack after baking.
Step 4: Fill the Cupcakes
Once cooled, use a cupcake corer or knife to make holes in the middle of each cake.
Step 5: Prepare the Lime Filling
- Add a little green food coloring to tinned custard and mix until you reach your desired color.
- Spoon this vibrant custard into each hole you’ve made in the cupcakes.
Step 6: Make the Buttercream

How to Perfect Halloween Slime Cupcakes
Perfecting your Halloween Slime Cupcakes is key to impressing your guests. Here are some tips to ensure they turn out just right.
- Use Room Temperature Ingredients: Ensure all ingredients, especially butter and eggs, are at room temperature for better mixing and texture.

- Check Oven Temperature: Use an oven thermometer to ensure your oven is at the correct temperature. This helps prevent overbaking or underbaking.
- Decorate Creatively: Use various toppings like edible glitter or themed sprinkles along with candy eyes for an extra festive look.
- Cool Completely Before Filling: Allow the cupcakes to cool fully before adding filling. This prevents melting and keeps the filling intact.
- Experiment with Flavors: While lime marmalade is delightful, feel free to try other fillings like raspberry or lemon curd for different flavor profiles.
