How to Make Halloween Slime Cupcakes

Follow these simple steps to prepare this delicious Halloween Slime Cupcakes:

Step 1: Preheat Oven and Prepare Tray

Pre-heat your oven to 140C Fan/325F/Gas Mark 3, and line a cupcake tin with cupcake cases, ideally black ones for that perfect spooky touch.

Step 2: Make the Batter

In a mixing bowl, combine the baking spread and caster sugar using an electric mixer until the mixture is smooth and fluffy, which should take about five minutes.

Step 3: Add Wet Ingredients

Add the eggs one at a time along with the vanilla extract, whisking thoroughly after each addition to ensure everything is well incorporated.

Step 4: Incorporate Dry Ingredients

Gently fold in the self-raising flour using a spatula or wooden spoon until just combined before adding black food coloring; mix until you have an even color throughout.

Step 5: Bake the Cupcakes

Spoon equal amounts of batter into each cupcake case and bake them in your preheated oven for 25-30 minutes or until a skewer inserted in the center comes out clean; let them cool completely on a rack afterward.

Step 6: Fill and Frost Your Cupcakes

Once cooled, use a cupcake corer or knife to create holes in each cake before filling them with lime-colored custard mixed with green food coloring; finish by piping bright green buttercream on top decorated with candy eyes and sprinkles for an eye-catching finish!
