How to make your Jack-O-Lantern Pumpkin Cake Step by Step

Step 1: Make up your cake batter

Make up your sponge cake batter using your own recipe or one of our handy cake mixes! Once well mixed, decant into your Wilton Jack-O-Lantern pumpkin tin and bake for the recommended time.

Step 2: Leave to cool.

Once baked, carefully remove your cake from the tin and leave it to cool. 

Judit says: “It’s important not to rush this step - make sure your cake has fully cooled before you begin to decorate. We don’t want to risk the buttercream design melting!”

Step 3: Make and Colour your Buttercream

While your cake is cooling, it's time to make and colour your buttercream! If you're using a ready-to-use frosting, you're halfway there. Add your flavouring, if desired - a little goes a long way. Then split your buttercream into separate bowls for each colour and add your chosen shades. For this beautiful autumnal version, Judit used Colour Mill’s Dusk, Latte, Peach, and Black.

Step 4: Prep your Piping Bags

Insert a piping tip into each piping bag - use a variety of shapes for an eye-catching look!

Step 5: Bring in your Cake Board

Place your fully cooled cake onto your chosen cake board - Judit went for a bold pink.

Step 6: Start Piping!

Add your buttercream into each bag and get piping! 

Judit advises: “Mix it up for a multi-tonal effect, placing one shape or colour next to another until you fill all the space. Try to avoid using too much of the same colour in one spot, for a more eye-catching effect!”

Step 7: Add some sprinkles

Finish off with a dash of your favourite sprinkles, and you're done!

Optional Step 8: Add a fondant leaf

Judit also used a leaf mould with fondant icing and gold edible dust to add some extra detail to the cake. If you have time, this is a gorgeous final touch! But the cake looks just as eye-catching without, so we'll leave that up to you!

Pumpkin-Shaped Cake Ideas

While we’re head over heels for this design, it isn’t the only option when it comes to this Halloween cake tin! Here are a few other colour palettes and styles you could use to decorate your Jack-O-Lantern showstopper.

Troubleshooting/FAQs

What food colouring is best for a pumpkin cake? 

For creating this type of buttercream topped pumpkin cake, we recommend using an oil-blend food colouring. It will achieve the best results in buttercream because they are designed to work with higher-fat content ingredients. The Colour Mill collection is excellent!

Do I need a special tin to make a Jack-O-Lantern cake? 

No - a specific pumpkin shaped tin is helpful when making a Jack-O-Lantern cake, but is not essential. You can use a classic round tin and then carve the shape by hand and with cookie cutters. This will be less precise but perfectly achievable!

Quick Troubleshooting Guide

Problem

Likely Culprit

Quick Fix

Cake won’t release from cake tin.

Forgetting to grease the cake tin before adding your batter.

The tin is non-stick, but we still advise greasing with some butter before adding your cake batter.

Buttercream isn’t turning the right colour.

You’re using the wrong colouring formula, e.g. a liquid colouring which will not emulsify (fully mix) with the fats in buttercream.

Use an oil-based colouring for best results with buttercream.

Buttercream is running off the cake.

  1. Cake hasn’t been left to cool for long enough.

  2. Buttercream is too thin.

  1. Leave the cake to cool for longer before decorating.

  2. Add a little more icing sugar to your buttercream.

Piping tip is popping out of the bag.

You may have cut too much off the end of the piping bag.

Start with a new bag and just snip the very end off, so that only the very tip of the piping nozzle is showing through.


We hope this jazzy Jack-O-Lantern Pumpkin cake has given you the creative inspiration you need to get baking this Halloween! These tins from Wilton make creating the perfect seasonal shaped cake so easy, and we can't wait to see your designs!
