How to Make Halloween Slime Cupcakes

Get your apron on and let’s dive into the fun of making these Halloween Slime Cupcakes!

Step 1: Preheat the Oven

Preheat your oven to 140°C Fan/325°F/Gas Mark 3. Line a cupcake tin with cupcake cases, ideally black ones to keep with the spooky theme.

Step 2: Cream the Butter and Sugar

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

Step 3: Add Eggs and Vanilla

Crack in the eggs one at a time and add the vanilla extract, whisking well to combine everything into a luscious mixture.

Step 4: Fold in the Flour

Gently fold the self-raising flour into the mixture, being careful not to deflate all that lovely air you’ve whipped in!

Step 5: Mix in the Black Magic

Add the black food coloring to your batter and mix it well, so the cupcakes take on their eerie color.

Step 6: Bake the Cupcakes

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

Step 7: Core the Cupcakes

Once your cupcakes are cool, use a cupcake corer or a knife to make a hole in the center of each one.

Step 8: Add the Zesty Filling

Take a bit of green food coloring and mix it into the tinned custard. Spoon the vibrant custard into each cupcake.

Step 9: Prepare the Buttercream

In another bowl, mix together the butter and icing sugar until smooth. Add the vanilla extract, milk, and both green and yellow food colorings until you achieve a bright, eye-popping green. If your buttercream is too stiff, add more milk until it’s the perfect consistency.

Step 10: Decorate Your Cupcakes

Using a piping bag (or just a spoon, if you prefer), generously pipe the bright green buttercream onto the cupcakes. Finish off your monstrous creations with candy eyes and sprinkles for a creepy-crawly touch!

Step 11: Store and Enjoy

Pop your spooky cupcakes into an airtight container and keep them in a cool place. Enjoy your creepy creations within three days!

Pro Tips for Making Halloween Slime Cupcakes

Room Temperature Ingredients: Ensure your butter and eggs are at room temperature for the best texture in your cupcakes.
Don’t Overmix: Mix just until combined to keep your cupcakes light and fluffy.
Check for Doneness: Use a skewer or toothpick to check for doneness; it should come out clean when the cupcakes are ready.
Get Creative with Presentation: Try different piping techniques for your buttercream to give each cupcake its own unique personality!
