Ingredients:
- 2 1/3 cups all-purpose flour (430g)
- 1 1/2 cups caster sugar (265g)
- 2 tablespoons unsweetened cocoa powder (optional, for a darker base)
- 2 teaspoons baking powder
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 3 large eggs, at room temperature
- 1/2 cup vegetable oil (125ml)
- 1 1/2 cups buttermilk (375ml), at room temperature
- 2 teaspoons pure vanilla extract
- 2 tablespoons blue food coloring (optional, for a deeper blue base)
- 1 batch of your favorite American buttercream or Swiss meringue buttercream (enough to frost approximately 24 cupcakes)
- For the galaxy frosting colors:
- Purple coloring: 2 drops deep pink food gel + 2 drops purple food gel
- Blue coloring: 2 drops sky blue food gel
- Pink coloring: 2 drops deep pink food gel
Preparing the Galaxy Cupcake Batter
Dry Ingredients:
In a large mixing bowl, whisk together the all-purpose flour, caster sugar, unsweetened cocoa powder (if using), baking powder, baking soda, and salt. Whisking these dry ingredients thoroughly ensures that the leavening agents and salt are evenly distributed, which will lead to a consistent rise and flavor in your cupcakes. If you’re omitting the cocoa powder and want a lighter base, you can skip that step. Ensure there are no clumps of flour or cocoa powder for the smoothest batter.
Wet Ingredients and Combining:
In a separate medium bowl, whisk together the large eggs, vegetable oil, buttermilk, and pure vanilla extract. It’s crucial that your eggs and buttermilk are at room temperature. This allows them to emulsify more readily with the other ingredients, creating a smoother, more stable batter and preventing the fat from solidifying. If you want your cupcake base to have a subtle blue hue to complement the galaxy theme, now is the time to add the optional blue food coloring. Add it to the wet ingredients and stir until it’s fully incorporated.
Now, it’s time to combine the wet and dry ingredients. Pour the wet ingredients into the bowl with the dry ingredients. Mix on low speed with an electric mixer (or by hand with a whisk) until just combined. Be careful not to overmix at this stage. Overmixing can develop the gluten in the flour too much, resulting in tough cupcakes. A few small lumps in the batter are perfectly fine. We’re aiming for a smooth, cohesive batter that’s not too thick or too thin.
Baking the Galaxy Cupcakes
Filling the Cupcake Liners:
Preheat your oven to 350°F (175°C). Line standard muffin tins with cupcake liners. I like to use liners that are a neutral color so the batter colors can shine through, or even a dark, speckled liner if you have them. Fill each cupcake liner about two-thirds full with the batter. This ensures that the cupcakes have room to rise without overflowing. Using an ice cream scoop or a measuring cup can help you fill them evenly for consistent baking.
Baking and Cooling:
Bake for 18-22 minutes, or until a wooden skewer or toothpick inserted into the center of a cupcake comes out clean. The exact baking time will depend on your oven, so it’s always best to check a few minutes before the minimum time. Once baked, remove the muffin tins from the oven and let the cupcakes cool in the tins for about 5-10 minutes. This initial cooling period in the tin helps them firm up slightly.
After this initial cooling, carefully transfer the cupcakes to a wire rack to cool completely. It’s extremely important that the cupcakes are completely cool before you begin extract frosting them. If you try to frost warm cupcakes, the frosting will melt and slide off, creating a messy, unappealing finish. Patience here is key to achieving beautiful galaxy cupcakes.
Decorating Your Galaxy Cupcakes
Preparing the Frosting Colors:
While your cupcakes are cooling, prepare your buttercream frosting and divide it into three separate bowls. You’ll need one bowl for purple, one for blue, and one for pink.
For the purple frosting, combine 2 drops of deep pink food gel with 2 drops of purple food gel in a bowl of your buttercream. Mix thoroughly until you achieve a rich, swirling purple hue.
For the blue frosting, add 2 drops of sky blue food gel to another bowl of buttercream and mix until well combined, creating a vibrant blue.
For the pink frosting, add 2 drops of deep pink food gel to the third bowl of buttercream and mix until you have a lovely pink shade. You may want to reserve a small amount of plain white frosting if you like to add tiny white dots for stars later.
Creating the Galaxy Effect:
Once your cupcakes are fully cooled and your frostings are colored, it’s time for the fun part – decorating! Take a small amount of each colored frosting (purple, blue, and pink) and place dollops of them randomly onto the surface of the cupcake. You don’t need to be precise here; a haphazard placement is perfect for the abstract nature of a galaxy.
Next, take a clean offset spatula or a butter knife and gently swirl the colors together. The key here is to swirl just enough to blend the colors and create streaks, but not so much that they become one muddy color. You want to see distinct ribbons of purple, blue, and pink. Don’t overwork it! This gentle swirling motion is what creates the nebulae and cosmic clouds effect. For a starry effect, you can use a small, clean paintbrush to flick tiny dots of white frosting (if you reserved some) or even a bit of edible glitter onto the swirled frosting. You can also use a toothpick to create small swirls or drag lines to enhance the cosmic look.
Enjoy the process and remember that each galaxy cupcake will be unique, just like the stars in the night sky!

Frequently Asked Questions:
Q1: How do I achieve the galaxy effect on the frosting?
A1: The key to the galaxy effect is layering and swirling. Start by frosting your cupcakes with a base color (like black or dark blue). Then, add dollops of other vibrant colors (purples, pinks, blues, white) on top. Use a toothpick or a skewer to gently swirl the colors together, being careful not to overmix, which will muddy the colors. Think of it like painting a starry sky – you want distinct swirls and blends, not a uniform mix.
Q2: Can I make the frosting ahead of time?
A2: Yes, you can definitely make the frosting ahead of time. Once it’s made, store it in an airtight container in the refrigerator for up to 3 days. Before using, let it come to room temperature and re-whip it with a mixer to ensure it’s smooth and spreadable. If it seems too stiff, you can add a tablespoon of milk or cream at a time until the desired consistency is reached.
Q3: What kind of food coloring works best for galaxy cupcakes?
A3: Gel food coloring is highly recommended for achieving vibrant and concentrated colors in your frosting, which is essential for the galaxy effect. Liquid food coloring can add too much moisture to the frosting, potentially affecting its texture and making it harder to achieve sharp swirls. Gel colors allow you to use less while still getting intense hues.
