Vanilla Cupcakes with Violet Buttercream and Gem Candies

Introduction

These vanilla cupcakes use a simple creamed batter, then get topped with violet buttercream, gold-dusted cake trimmings, and gem candies arranged like small crowns. You get a standard 12-cupcake batch with a decorative finish that works well for birthdays, themed parties, or any time you want a straightforward vanilla base with more visual detail.

• Cook Time: 20 minutes
• Total Time: 55 minutes
• Servings: 12

Ingredients

Cakes

• ⅔ cup (160 g/5.6 oz) margarine
• ⅔ cup (150 g) superfine sugar
• 2 eggs
• 1 cup (140 g) self-rising flour
• 3 tablespoons milk
• 1 teaspoon vanilla powder (use half this amount if you prefer less rich vanilla flavor)

Frosting

• 1¼ sticks (160 g) butter
• 2½ cups (310 g) powdered sugar
• 15 g tube violet extra-strong food coloring gel
• 60 mini gem candies, 12 yellow reserved
• Edible gold glitter spray

Instructions

Cakes

1. Preheat the oven to 180 C. Line an 12-hole cupcake pan with cupcake cases.
2. Beat the butter and sugar in a bowl until creamy.
3. Beat in the eggs, one by one.
4. Fold in the flour. Stir in milk and vanilla.
5. Spoon the mixture into the cupcake cases.
6. Bake for 18-20 minutes until golden.
7. Transfer the cupcakes to a wire rack and leave it to cool.

Frosting

1. Beat the butter in another bowl until light.
2. Beat in the powdered sugar, 1 cup at a time.
3. Beat in the food coloring.

Assembly

1. Using a teaspoon or a serrated knife and starting near the edges, remove the risen top on each cupcake. Be sure to keep the tops intact.
2. Cut each top into 4 quarters and dust with a little edible gold spray.
3. Put 2 tablespoons of the buttercream into a piping bag with a 5 mm hole, and put the rest into another piping bag with a 2 cm hole.
4. Using the bag with the larger hole, pipe a mound of frosting on top of each cupcake, starting near the edge and moving towards the center.
5. Top each cupcake with 4 gold trimmings, standing them upright. Space them evenly around the edges, and press them into the frosting to adhere them. It should look like 4 fans sticking out of the frosting to give the appearance of a crown.
6. Arrange the non-yellow gems on the frosting between the fans, pressing gently to make sure they stick.
7. Using the piping back with the smaller hole, pipe a small blob atop the center of each mound of frosting. Spray with a little gold spray.
8. Dust the yellow gems with glitter, and place one on top of the center blob of each cupcake.
9. Dust each cupcake with a little extra glitter and serve.

Variations

• Change the violet extra-strong food coloring gel to another gel color if you want the same frosting texture with a different look. Blue, pink, or green all work without changing the structure.
• Replace the vanilla powder (use half this amount if you prefer less rich vanilla flavor) with finely ground almonds (use 1–2 tbsp for subtle flavor; add more if desired) in the cakes if you want a sharper, more bakery-style flavor. The cupcakes will taste less neutral and more distinctly sweet.
• Use butter instead of margarine in the cakes for a firmer crumb and a richer butter flavor. The cupcakes may feel slightly less soft at room temperature.
• Skip the step of cutting and quartering the cupcake tops if you want a faster finish. You lose the crown effect, but the cupcakes are easier to decorate and transport.
• Swap the mini gem candies for other small candy-coated chocolates or sturdy sprinkles. That keeps the color contrast but changes the crunch and overall appearance.

Tips for Success

• Beat the margarine and superfine sugar until fully creamy before adding the eggs. If that base is undermixed, the cupcakes tend to bake up heavier.
• Add the eggs one at a time as written so the batter stays smoother and emulsifies properly.
• Start checking the cakes at the 18-minute mark. They are done when the tops are golden and spring back lightly when pressed.
• Let the cupcakes cool completely on the wire rack before piping the buttercream. Warm cakes will soften the frosting and make the gem candies slide.
• When removing the risen tops, start near the edges with a teaspoon or serrated knife so the quarters stay intact for the crown decoration.

Storage and Reheating

Store the finished cupcakes in a single layer in an airtight container in the fridge for up to 3 days. If you need to stack them, use a tall container so the frosting and crown pieces do not get crushed.

Freeze unfrosted cupcakes in an airtight container or freezer bag for up to 2 months. Fully decorated cupcakes are not good freezer candidates because the buttercream texture changes and the gem candies can soften or bleed color.

Do not reheat the finished cupcakes. For the best texture, take chilled cupcakes out of the fridge and let them sit at room temperature for 20 to 30 minutes before serving; if frozen unfrosted cupcakes, thaw them wrapped at room temperature, then frost once fully thawed.

FAQ

Can you make these cupcakes a day ahead?

Yes. Bake and frost them a day ahead, then store them covered in the fridge and bring them back to room temperature before serving.

Do you need two piping bags for the frosting?

No, but two bags make the crown design cleaner. If you only have one, pipe the large mounds first, then refill or trim the opening smaller for the center blobs.

Can you use butter instead of margarine in the cakes?

Yes. Butter gives you a richer flavor and a slightly firmer crumb, but the cupcakes will still work the same way.

Can these be made dairy-free?

You can use plant-based margarine in the cakes and a dairy-free block-style butter alternative in the frosting, but you should also check the mini gem candies to make sure they fit your needs. The final texture of the frosting may be a little softer depending on the brand.
