Ingredients for Galaxy Cupcakes
It’s time to turn basics into brilliance. Let’s see what you’ll need.
All-purpose flour: The backbone of our cupcakes, providing structure and a soft texture.
Granulated sugar: Sweetness is key! It balances the rich chocolate flavor and adds moisture.
Unsweetened cocoa powder: This is where the chocolate magic happens, giving our cupcakes that deep, rich flavor.
Baking soda and baking powder: These leavening agents help our cupcakes rise, making them light and fluffy.
Salt: A pinch enhances all the flavors, making each bite more delicious.
Large egg: Eggs add moisture and richness, helping to bind everything together.
Whole milk: This adds creaminess and helps create a tender crumb.
Vegetable oil: For moisture and a soft texture, oil keeps our cupcakes from being dry.
Vanilla extract: A splash of vanilla adds warmth and depth to the flavor profile.
Boiling water: This may sound odd, but it helps to bloom the cocoa powder, intensifying the chocolate flavor.
Food coloring (blue, purple, pink): These vibrant colors will create the galaxy effect in our frosting.
For the buttercream frosting, you’ll need:
Unsalted butter: Softened butter is essential for a creamy, smooth frosting.
Powdered sugar: This sweetens the frosting and gives it that fluffy texture we all love.
Vanilla extract: Just like in the cupcakes, it adds a lovely flavor to the frosting.
Heavy cream: This helps achieve the perfect consistency for spreading or piping.
Food coloring (blue, purple, pink): Again, these colors will help us create that stunning galaxy look.

How to Make Galaxy Cupcakes
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C). This ensures your Galaxy Cupcakes bake evenly. While the oven warms up, line a muffin tin with cupcake liners. Choose colorful ones to match the galaxy theme. This small detail adds a fun touch to your baking adventure!
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine the all-purpose flour, granulated sugar, cocoa powder, baking soda, baking powder, and salt. Whisk them together until well blended. This step is crucial for ensuring your cupcakes rise perfectly and have a consistent flavor throughout. Trust me, it makes a difference!
Step 3: Add Wet Ingredients
Now, it’s time to add the wet ingredients. Crack in the large egg, pour in the whole milk, vegetable oil, and vanilla extract. Mix everything together until just combined. Don’t overmix; a few lumps are okay! This will keep your cupcakes light and fluffy, just like a cloud in space.
Step 4: Stir in Boiling Water
Carefully stir in the boiling water. Yes, it sounds strange, but this step is essential! The hot water helps bloom the cocoa powder, enhancing the chocolate flavor. Your batter will be thin, but that’s exactly what you want for moist, delicious cupcakes. Embrace the magic!
Step 5: Fill Cupcake Liners
Divide the batter evenly among the cupcake liners, filling each about two-thirds full. This allows room for the cupcakes to rise without overflowing. Use a measuring cup or a ladle for precision. It’s all about creating that perfect galaxy shape, after all!
Step 6: Bake the Cupcakes
Place the muffin tin in the preheated oven and bake for 18-20 minutes. Keep an eye on them! You’ll know they’re done when a toothpick inserted into the center comes out clean. Let them cool in the pan for about 5 minutes before transferring them to a wire rack. Patience is key!
Step 7: Prepare Buttercream Frosting
While the cupcakes cool, it’s time to whip up the buttercream frosting. In a large bowl, beat the softened unsalted butter until creamy. Gradually add the powdered sugar, mixing well. This will create a fluffy base for your galaxy colors. It’s like crafting a cloud of sweetness!
Step 8: Color the Frosting
Divide the frosting into three bowls. Color one bowl blue, another purple, and the last pink using food coloring. Mix until you achieve vibrant shades. This is where the fun begins! The colors will create that stunning galaxy effect when you frost the cupcakes.
Step 9: Frost the Cupcakes
Now, it’s time to frost your cooled cupcakes! Using a piping bag or a spatula, swirl the different colored frostings together to create a galaxy look. Don’t be afraid to get creative! Each cupcake can be a unique piece of art, just like the stars in the night sky.
Tips for Success
Always measure your ingredients accurately for the best results.
Let your cupcakes cool completely before frosting to prevent melting.
Use gel food coloring for more vibrant hues in your frosting.
Experiment with different flavor extracts in the buttercream for a unique twist.
For a fun touch, add edible glitter or star-shaped sprinkles on top!
Equipment Needed
Muffin tin: Essential for baking your cupcakes. A silicone mold works too!
Mixing bowls: Use a large bowl for dry ingredients and a medium one for wet. Any size will do.
Whisk: Perfect for blending ingredients. A fork can work in a pinch!
Piping bag: Ideal for frosting. A zip-top bag with the corner cut off works just as well.
Measuring cups and spoons: Accurate measurements are key. A kitchen scale is a great alternative.
Variations
Gluten-free option: Substitute all-purpose flour with a gluten-free blend to make these cupcakes suitable for those with gluten sensitivities.
Vegan twist: Replace the egg with a flaxseed meal or applesauce, and use plant-based milk and oil for a delicious vegan version.
Flavorful additions: Try adding a teaspoon of espresso powder to the batter for a mocha flavor or a splash of almond extract for a nutty twist.
Fruit-infused frosting: Mix in pureed fruit like strawberries or raspberries into the buttercream for a fruity flavor and a pop of color.
Mini cupcakes: Use a mini muffin tin to create bite-sized galaxy cupcakes, perfect for parties or gatherings!
