How to Make Halloween Slime Cupcakes

Get your baking hats on! Follow these easy steps to whip up your very own Halloween Slime Cupcakes:

Step 1: Preheat the Oven

Set your oven to 140°C Fan / 325°F / Gas Mark 3, and line a cupcake tin with black cupcake cases for that spooky vibe!

Step 2: Create the Cupcake Batter

In a large bowl, combine the baking spread and caster sugar. Using an electric mixer, beat them together for about 5 minutes until the mixture is smooth and fluffy.

Step 3: Add the Eggs and Vanilla

Crack in the eggs and pour in the vanilla extract. Whisk together until well combined and fluffy.

Step 4: Mix in the Flour

Gently fold in the self-raising flour until just combined. You want that light and airy texture!

Step 5: Bring in the Dark Side

Pour in the black food coloring and mix well, ensuring the batter takes on a hauntingly dark hue.

Step 6: Bake the Cupcakes

Divide the batter evenly among the cupcake cases. Bake for 25-30 minutes, or until a skewer inserted into the center comes out clean. Transfer them to a wire rack to cool completely.

Step 7: Fill the Cupcakes

Once cooled, use a cupcake corer or a knife to create holes in the middle of each cupcake.

Step 8: Make it Slimey

Add a drop of green food coloring to the custard and mix. Spoon it generously into each cupcake hole.

Step 9: Whisk the Buttercream

In another bowl, mix together the softened butter and icing sugar until smooth. Add the vanilla extract, milk, and green/yellow food coloring until you reach a brilliant green color. Adjust with more milk if the buttercream is too stiff.

Step 10: Decorate the Cupcakes

Using a piping bag, pipe the luscious buttercream onto your cupcakes, or simply spread it on with a spoon. Top each cupcake with candy eyes and a sprinkle of green magic!

Step 11: Store Your Treats

Keep your Halloween Slime Cupcakes in an airtight container in a cool place, and enjoy them within 3 days!

Pro Tips for Making Halloween Slime Cupcakes

– Use Room Temperature Ingredients: Ensure your butter and eggs are at room temperature for smooth and easy mixing.
– Don’t Overmix: When adding the flour, mix just until combined to keep your cupcakes light and fluffy.
– Chill the Buttercream: If the buttercream is too soft, refrigerate it for a few minutes to help it hold its shape when piping.
– Experiment with Colors: Get creative with your food coloring to make each cupcake uniquely festive!
