Cactus Cupcakes

A fun design made with buttercream cactus and chocolate liners

Buttercream cactus cupcakes in edible chocolate flower pots topped with pink and purple candy melt flowers and biscuit crumb soil.

I started making cactus cupcakes like this years ago as a way to create taller, more realistic buttercream cacti without using inedible supports. By piping the buttercream around a chocolate-coated pocky stick, the cactus can stand upright while still being completely edible.

Since then, I’ve used this technique in so many different cupcake designs because it’s such a simple way to add height and dimension to buttercream decorations. These cactus cupcakes are finished in homemade chocolate pots filled with biscuit “soil” and topped with candy melt flowers for a fun plant-inspired dessert that always gets attention.

The Cactus Cupcake Design

These cactus cupcakes are made using chocolate cupcake “pots” filled with biscuit crumbs to resemble soil, then topped with tall buttercream cacti piped onto chocolate-coated pocky sticks. The buttercream is piped using a large star tip to create realistic cactus ridges before being finished with coconut “spikes” and small candy melt flowers.

I used different shades of green buttercream throughout the designs to give each cactus its own personality and succulent-inspired colouring. The chocolate pots are made by brushing candy melts inside cupcake liners, creating an easy edible container that can be customised for different themes and colours.

Although the cupcakes look detailed, the overall method is surprisingly simple once broken down into steps. The combination of texture, colour and height helps the finished design really stand out.

The edible liners are made using candy melts and do take a little patience. Working in thin layers and allowing each one to set properly helps prevent cracking. If you are new to working with candy melts, my Working with Candy Melts guide walks through the process step by step.

I recommend using my Basic Buttercream for this design, as the American-style consistency is firm enough to hold the cactus shape properly.

Things Used

Candy Melts

I used white candy melts for this design and coloured them using Colour Mill Oil Blend in the shade Rust. Candy melts and compound chocolate melt smoothly and set firm without the need for tempering, making them ideal for edible cupcake liners and decorations.

Baking Cups

I used the thick card baking cups from Papyrus as the mould for the edible chocolate wrappers. They are the perfect size and shape for a cupcake to sit inside and create the scalloped flower pot edge around the top.

Once the chocolate has fully set, the wrapper pushes away cleanly from the baking cup so the moulds can easily be reused for future designs. The thicker card cups also help the chocolate hold its shape better while setting compared to standard paper liners.

Chocolate Cupcakes

My Chocolate Cupcakes are the perfect choice for this design. Make sure they are fully cooled before assembling. If needed, trim the dome so that the cupcakes sit lower inside the edible liner.

Pocky Sticks

I used chocolate-coated pocky sticks as the edible support for the buttercream cactus. The sticks help create extra height while still being completely edible, making them a fun alternative to traditional inedible supports.

Buttercream

A stable buttercream is essential for piping the tall cactus. I use my Basic Buttercream, as the consistency is firm enough to hold shape while still piping smoothly.

Piping Tip 8B

I used piping tip 8B for the cactus, as the large open star shape creates the textured ridges that give the buttercream its realistic cactus appearance. The opening is also wide enough to pipe directly over the chocolate-coated pocky sticks, helping create the tall upright shape without crushing the buttercream.

Sturdy Piping Bags

I recommend using thick, sturdy piping bags for this design, as the piping tip and bag both need to slide carefully over the chocolate-coated pocky stick while piping. Flimsy bags can split under the pressure, especially when using firmer buttercream.

Keeping the piping bag fairly full also helps maintain even pressure and creates smoother cactus ridges as you pipe upward around the stick.

Gel Colour

I used gel colouring in two different shades of green to give the cactus a more realistic succulent-style finish. Adding multiple shades directly into the piping bag creates natural variation throughout the buttercream without needing to fully mix the colours together.

Chocolate Ganache

I used chocolate ganache on top of the cupcakes before adding the biscuit crumb “soil,” as it creates a rich flavour and helps hold the crumbs neatly in place. Buttercream also works perfectly for this step if you prefer a quicker option or want to match the cupcake frosting flavour.

Crushed Biscoff Biscuits

I used crushed Biscoff biscuits to create the “soil” effect on top of the cupcakes. The fine crumbs give a realistic dirt-like texture while adding extra flavour that pairs perfectly with the chocolate cupcake and ganache.

You can crush the biscuits in a food processor or place them into a zip-lock bag and crush them with a rolling pin until fine. Chocolate cake crumbs or crushed Oreos also work well as alternatives.

Silicone Flower Mould

I used a silicone flower mould to create the cactus flowers, but there are lots of easy alternatives depending on what you have available. Small icing decorations, sprinkles or piped buttercream flowers all work beautifully for this design.

The flowers are a fun way to add extra colour and personality to each cactus, and they can easily be customised to suit different themes or occasions.

Desiccated Coconut

I used desiccated coconut to create the tiny cactus “spikes” on the buttercream. After piping the cactus, I gently sprinkled the coconut over the buttercream through a small sieve so it coated the ridges evenly without clumping.

This simple step adds extra texture and helps give the cactus a more realistic finish. Fine shredded coconut works best, as larger pieces can look bulky against the buttercream ridges.

How to...

Two shades of green buttercream prepared for piping realistic cactus cupcakes.

Step 1

Make a batch of my Basic Buttercream and reserve around 1 cup for later if you are using it instead of the chocolate ganache. Colour the remaining buttercream green using gel colouring.

I made two different shades of green for the cactus to give a more realistic succulent-style effect, but you can absolutely use just one shade if preferred. Cover and set aside for now.

Step 2

Melt the white candy melts using short bursts in the microwave, stirring well between each burst to prevent overheating. Once smooth, colour the melts using oil-based colouring.

If the candy melts feel too thick, add a small amount of vegetable shortening and stir until smooth and pourable. This helps thin the melts and makes them much easier to brush inside the cupcake liners.

Step 3

Working on one baking cup at a time, pour around 1 tablespoon of the melted candy melts into the bottom of the baking liner.

Step 4

Turn the baking cup slowly to coat the sides evenly with the melted candy melts, allowing the excess to run back into the bowl. Gently tap the sides to help move the melts up towards the edges and create a more even coating. Let them fully before moving to the next layer.

Step 5

Once the first layer has fully set, add more melted candy melts into the liner and use a small brush or spoon to coat the sides with a second layer. Pay extra attention to the edges and corners, as these areas are more likely to crack if they are too thin.

Continue coating all of the liners, then place them into the freezer for around 10 minutes, or until fully set and the coating feels solid.

Step 7

Remove the wrappers from the baked cupcakes, if needed, trim a small amount from the bottom or top of the cupcake so it sits slightly lower inside the liner. Sit the cupcakes into the chocolate liners and gently press them into place using the back of a spoon.

Step 8

Add the chocolate ganache, if using, otherwise spread a thin layer of the reserved buttercream over the top of the cupcake. It does not need to look perfect, as it will be completely covered with the biscuit crumb “soil.”

Step 9

Use a spoon to scatter the biscuit crumb “soil” around the edges of the cupcake, leaving a small space in the centre where the cactus will sit. This helps the buttercream cactus stick securely to the cupcake, as buttercream does not attach well to loose crumbs.

Step 10

Push a pocky stick into the middle of each cupcake. You can trim them to size first, depending on how tall you would like the cactus to be. Set the cupcakes aside for now.

Step 17

Continue adding the desiccated coconut by gently turning the cactus to coat all sides evenly. Try to keep most of the coconut on the buttercream rather than the biscuit “soil.” Any excess can easily be brushed away or covered with extra biscuit crumbs if needed.

Step 18

Attach the flowers to the top of each cactus. You can use a small amount of buttercream on the back of the flowers if needed to help secure them in place.

I used homemade candy melt flowers made with a silicone mould, but any flowers you choose will look beautiful. Buttercream flowers, sprinkles or ready-made icing decorations all work well for this design.
