Ingredients You’ll Need
The beauty of this Milky Way Galaxy Cupcakes Recipe lies not only in its stunning appearance but also in the simplicity and quality of the ingredients. Every component plays a vital role—from the flour that gives the cupcakes their light texture to the cocoa powder that adds that deep chocolate richness, and finally to the vibrant gel food colorings that bring the galaxy theme to life.
- All-purpose flour (1 1/2 cups): Provides the perfect structure for a soft, yet sturdy cupcake base.
- Baking powder (1 1/2 tsp): Helps the cupcakes rise and become fluffy.
- Baking soda (1/2 tsp): Adds extra lift and balances acidity.
- Salt (1/4 tsp): Enhances the chocolate flavor and balances sweetness.
- Unsweetened cocoa powder (1/2 cup): The star of the cake’s chocolate flavor, giving it depth and richness.
- Granulated sugar (1/2 cup): Adds essential sweetness and tenderizes the crumb.
- Light brown sugar, packed (1/2 cup): Gives moisture and a subtle caramel note.
- Unsalted butter, softened (1/2 cup + 1 cup): Both the cupcake and frosting rely on butter for creaminess and flavor.
- Large eggs (2): Bind the ingredients together and add richness.
- Vanilla extract (1 tsp): Brings warmth and enhances all the flavors.
- Milk or dairy-free alternative (1/2 cup + 1-2 tbsp): Keeps the batter moist and helps the frosting reach the perfect texture.
- Boiling water (1/2 cup): Unlocks the full cocoa flavor by blooming the cocoa powder.
- Powdered sugar (4 cups): Essential for that luscious, smooth frosting.
- Gel food coloring (blue, purple, black, and white): The magic potion that transforms the frosting into a galaxy of colors.
- Edible glitter or star sprinkles (optional): Adds a twinkling star-like finish to your cupcakes.
How to Make Milky Way Galaxy Cupcakes Recipe
Step 1: Prepare the Cupcake Batter
Start by preheating your oven to 350°F (175°C) and lining a 12-cup muffin tin with cupcake liners—it’s important to have everything ready so you can move quickly once your batter is mixed. Combine the flour, cocoa powder, baking powder, baking soda, and salt in a medium bowl for the dry ingredients. This mixture provides the foundation for those rich chocolatey cupcakes that will serve as your ‘galaxy’ canvas.
Step 2: Cream the Butter and Sugars
In a large bowl, beat the softened butter with the granulated and brown sugars until the mixture is fluffy and light, about three minutes. This step is crucial because it incorporates air, ensuring your cupcakes stay tender and moist. The mix of brown and granulated sugar adds both sweetness and moisture, giving the cake a subtle complexity.
Step 3: Add Eggs and Vanilla
Beat in the eggs one at a time, making sure each is fully incorporated before adding the next. Then stir in the vanilla extract. These add richness and depth to your cupcake batter and help balance the cocoa’s intensity.
Step 4: Combine Wet and Dry Ingredients
Alternately add the dry ingredients and the milk to the butter mixture, starting and ending with the dry ingredients. Mixing just until combined prevents overworking the batter, which keeps your cupcakes tender. Then, carefully mix in the boiling water—the batter will be thin, which is expected and helps create a moist crumb.
Step 5: Bake the Cupcakes
Divide the batter evenly among the cupcake liners, filling each about two-thirds full. Bake for 18 to 20 minutes or until a toothpick inserted in the center comes out clean. Once done, transfer the cupcakes to a wire rack and let them cool completely before frosting. This cooling step is key for your frosting to stay smooth and not melt.
Step 6: Craft the Galaxy Frosting
Beat the softened butter until creamy, then gradually incorporate powdered sugar one cup at a time over low speed. Add the vanilla extract and milk, adjusting to get the perfect smooth, pipeable consistency. Divide the frosting into four bowls and tint each with gel food coloring—blue, purple, black, and white—to bring the galaxy to life.
Step 7: Frost Your Cupcakes
Using a piping bag or a zip-top bag with the tip cut off, start by layering one color of frosting on each cupcake. Add other colors in swirls and gently marble them together with a spatula or the back of a spoon. Finish with a generous sprinkle of edible glitter or star sprinkles to mimic the sparkling stars of the Milky Way. Let the frosting set for a few minutes before serving.
How to Serve Milky Way Galaxy Cupcakes Recipe

Garnishes
To really elevate your cosmic creations, consider topping the frosting with a sprinkle of edible glitter or shimmering star-shaped sprinkles. These little touches catch the light beautifully, making the cupcake look like a tiny piece of the galaxy itself. You can also add tiny silver dragees for some extra sparkle and elegance.
Side Dishes
Milky Way Galaxy Cupcakes shine as a star dessert and pair wonderfully with simple vanilla bean ice cream or fresh berries. For a party, try serving them alongside a cool glass of milk or a rich hot chocolate to complement the chocolatey depths of the cupcakes and keep the focus on this celestial treat.
Creative Ways to Present
For a truly out-of-this-world display, arrange your cupcakes on a round platter and sprinkle edible star confetti around them. You might also try serving them inside mini cake domes or glass cloches to give your guests a sense of unveiling the mysteries of the galaxy. Using cupcake stands with varying heights can add dimension and make the presentation feel like a star-studded night sky.
Make Ahead and Storage
Storing Leftovers
Once decorated, keep your Milky Way Galaxy Cupcakes Recipe in an airtight container at room temperature if you plan to eat them within 2 days. Avoid refrigerating as this can dry out the cupcakes and cause the frosting to firm too much.
Freezing
You can freeze the baked but unfrosted cupcakes by wrapping them tightly in plastic wrap and placing them in a freezer-safe bag or container for up to 3 months. When you’re ready to use them, thaw at room temperature and frost as usual. For cupcakes with frosting, flash freeze them on a tray first, then store in airtight containers. Defrost gently to preserve frosting texture.
Reheating
For a warm treat, gently microwave the cupcake (without frosting) for about 10-15 seconds. If you want your frosting slightly softened, let the cupcake sit at room temperature for 15-20 minutes. Avoid overheating, which can melt the frosting and affect its look and texture.
FAQs
Can I use dairy-free alternatives in this Milky Way Galaxy Cupcakes Recipe?
Absolutely! You can substitute milk and butter with any dairy-free alternatives like almond milk or coconut oil-based butter. Just make sure the porportions are the same, and note that it might slightly alter the flavor but will still be delicious.
How do I get the best galaxy swirl effect with the frosting?
Use gel food coloring for vibrant colors and avoid liquid food coloring that can thin the frosting. Pipe different colors side by side and gently swirl once on the cupcake surface with a spatula or spoon for a marbled galaxy effect without mixing too much.
Can I make these cupcakes ahead of time for a party?
Definitely! Bake the cupcakes a day or two before your event and keep them in an airtight container. Frost them the day of, or frost and store them overnight if refrigeration is needed—just bring them back to room temperature before serving.
What is the best way to avoid cupcakes sticking to liners?
Make sure to use good-quality cupcake liners and avoid overbaking. Also, allow cupcakes to cool completely before removing liners if you prefer to unwrap them. Using non-stick liners or a light spray can also help.
Is it safe to eat edible glitter and sprinkles?
Yes! Make sure you purchase edible glitter and sprinkles labeled as food-safe. Avoid craft glitters since they are not meant for consumption. These edible decorations add sparkle and fun to your Milky Way Galaxy Cupcakes Recipe without any worries.
