Blueberry Cupcakes

A fun design made with buttercream blueberries and chocolate liners

Blueberry cupcakes decorated with buttercream blueberries in homemade yellow and white striped candy melt cups.

So many people loved my buttercream popcorn cupcakes and suggested a blueberry version, so I decided to bring the idea to life. Pairing the buttercream blueberries with my striped candy melt cups was exactly what this design needed.

The original popcorn cupcakes quickly became one of my favourite designs, and recreating them with a blueberry twist completely changed the feel of the cupcakes. The yellow and white striped cups give them a fun summer dessert vibe, while the buttercream blueberries add texture and detail that make them feel extra special.

The Blueberry Cupcake Design

The blueberries are piped using buttercream in different shades of blue to help create a more realistic look. I used The Microwave Method to deepen the colour without affecting the texture or taste of the buttercream. The colour deepens over time, so if you have time then i’d recommend preparing your buttercream the day before.

Although the cupcakes look detailed, the overall method is surprisingly simple once broken down into steps. Once everything comes together, the combination of texture, colour, and shape makes the design really stand out.

The edible liners are made using candy melts, and while they are very achievable, they do take a bit of patience. Working in thin layers and letting each one set properly helps prevent cracking. If you are new to this technique, my Working with Candy Melts guide will walk you through it step by step.

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

Things I Used

Candy Melts

I used pre coloured yellow and white candy melts for this design, it melts smoothly and sets firm without tempering. If you can’t find the pre coloured melts then you can add Colour Mill oil blend to white compound chocolate. You can read more about working with compound chocolate and candy melts in my Candy Melts for Beginners Guide

Baking Cups

I used the thick card gelato cups as the mould for the edible chocolate wrappers. They are the perfect size and shape for a cupcake to sit into. Once the chocolate has set, it pushes cleanly from the gelato cup so they can be reused.

Decorating Brush

A small decorating brush is used to paint the red stripes inside the liners. A soft brush gives you more control and helps keep the layers thin and even.

Lemon Cupcakes

My Lemon 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.

Buttercream

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

Piping Tip 14

A small star piping tip creates the soft, rounded shapes needed for the blueberry effect. The shape allows the buttercream to puff up naturally as pressure builds.

Sturdy Piping Bags

Extra thick piping bags are important for this technique. Piping the popcorn requires sustained pressure, and thinner bags can split, especially if the buttercream is firm. Doubling up piping bags also works well.

Baking Sheet and Parchment Paper

Used for piping the buttercream popcorn before freezing. The parchment paper allows the popcorn pieces to release easily once frozen.

Freezer Safe Tray

A tray that fits into your freezer is needed to chill both the buttercream popcorn and the chocolate liners during the process.

Colour Mill Navy and Purple oil Colour

I added a drop of purple to the buttercream along with the navy blens.

Ingredients

  • 12 Lemon cupcakes
  • A batch of my basic buttercream
  • 1 Cup candy melts (yellow)
  • 1 Cup candy melts (white)
  • 2 Tbsp vegetable shortening
  • Navy food colouring
  • Purple food colouring

Equipment

  • 12 Baking cups
  • A baking tray/ board (sized for the fridge)
  • A sheet of parchment paper
  • A small decorating brush
  • Small microwave safe bowls
  • A small spoon
  • Piping bags
  • A small star piping tip (14)

How to...

Yellow candy melts melted in a bowl beside paper cups and a pastry brush for making striped chocolate cupcake liners.

Step 1

Melt the yellow and white candy melts in separate bowls using short bursts in the microwave, stirring well between each burst to avoid overheating.

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

Step 2

Using a food-safe brush, paint vertical yellow stripes inside the baking cupcake cups.
Leave even gaps between each stripe for the white chocolate.
Let the yellow layer set completely.

Step 3

Once the yellow has set, brush white candy melts into the gaps between the yellow stripes. Allow this layer to set fully before adding more chocolate. Repeat the process, building up thin layers: yellow → set → white → set.
Continue until the sides feel sturdy and evenly coated.

Step 4

Spoon white candy melts into the bottom of each cup, tilting gently so it spreads evenly and seals the base. Once the chocolate cups are fully layered, place them in the fridge to set. While they’re chilling, you can make the buttercream blueberries so everything is ready for assembly.

Step 5

Make a batch of my Basic Buttercream and reserve a cupful for later.  Colour the remaining buttercream blue. I used navy with a small amount of purple to create the shade.

Add the blue buttercream to a piping bag fitted with a small star tip (14). I recommend using a strong piping bag for this step, as the pressure needed to pipe the blueberries can cause thinner bags to burst.

Step 6

Hold the piping bag upright with the tip fully touching the parchment paper.
Squeeze the bag to anchor a small amount of buttercream to the surface whilst keeping the piping tip in the same position. I recommend holding the top of the bag with two hands, as you need to squeeze firmly for the buttercream to begin puffing up.

Step 7

Keep squeezing firmly, holding the piping bag in the same position without lifting it. At this stage it can feel like the piping bag is going to burst — this is normal, which is why strong, good-quality piping bags are essential. As you continue squeezing, the buttercream will build and naturally rise up around the piping tip, forming a rounded base.

Step 8

Once the buttercream has popped up and formed the blueberry shape, stop squeezing and carefully lift the piping tip straight up and away, leaving the buttercream on the parchment paper. Wipe the piping tip clean between each blueberry.

Step 9

Repeat this process to pipe all of the blueberries onto the parchment paper. Place the tray in the freezer for 15 minutes, or until the buttercream is firm and easy to handle.

Step 10

While the buttercream is firming up in the freezer, remove the chocolate cups from the fridge. If you’re using the same style cups as me, they release very easily. Turn each cup upside down and gently tap it, the chocolate cup will pop straight out onto the parchment paper.

Step 11

Remove the wrappers from the lemon cupcakes and, if needed, trim a small amount from the bottom so the cupcake sits slightly lower in the cup. This leaves enough space for the buttercream blueberry topping.

Sit the cupcakes into the chocolate liners.

Step 13

Spoon or pipe a small amount of the reserved buttercream over the top and smooth it out. This seals the cupcake in place and creates a sticky surface for the blueberries to attach to. You only need a thin layer here, just enough to hold the blueberries, not a thick swirl.

Step 14

Add the blueberry pieces one at a time, placing them at slightly different angles. This stops them from lining up and looking like flowers. If needed, add a small dab of buttercream to the bottom of each piece to help hold it in place.

Step 15

Continue adding the blueberry pieces, filling in the gaps as you go.
If they start to soften and become hard to handle, pop them back in the freezer for a few minutes. Once in place, they’ll hold their shape perfectly.

The Results! Well done.

And that’s a wrap! Blueberry cupcakes, done!
