How to Make Out-of-this-World Galaxy Cupcakes
Step 1: Prepare Equipment
Preheat oven to 320°F (160°C) fan-forced or 356°F (180°C) conventional. Line 20 cupcake tins with liners.
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine flour, sugar, cocoa powder (if using), baking powder, baking soda, and salt. Mix on low speed until well combined, or sift together if mixing by hand.
Step 3: Combine Wet Ingredients
Combine eggs, vegetable oil, buttermilk, vanilla extract, and blue food coloring (if desired) in a large jug, whisking until well blended.
Step 4: Make Cupcake Batter
Gradually add wet ingredients to dry ingredients while mixing on low speed. Stop mixer, scrape bowl sides, and mix for 20 more seconds until smooth.
Step 5: Bake Cupcakes
Fill cupcake liners halfway with batter. Bake for 30 minutes until tops are shiny and bounce back when touched. Cool on wire rack before decorating.
Step 6: Prepare Cupcakes for Filling
After the cupcakes have cooled, use a cupcake corer or a small knife to remove the centers. Fill the holes with star sprinkles for a fun surprise.
Step 7: Color the Frosting
Separate the prepared buttercream frosting into three bowls. Color one bowl purple, one blue, and one pink following the color combinations listed. Mix each color thoroughly using a spatula.
Step 8: Method 1: Layer Frosting in Piping Bag
Attach a Wilton 6B tip to a piping bag and secure it in a tall cup. Fill the bag with alternating colors of frosting, adding 1 teaspoon of each until it is slightly over half full.
Step 9: Method 2: Plastic Wrap Technique
Transfer each colored frosting to individual piping bags. Pipe lines of each color side by side on a large piece of plastic wrap, leaving a small gap at the top and bottom. Roll the plastic wrap into a log, twist the ends, and cut off one end. Insert the wrapped frosting log into a piping bag with a Wilton 6B tip.
Step 10: Frost and Decorate
Pipe a swirl of frosting on top of each cupcake, starting from the outer edge and moving towards the center. Sprinkle with edible glitter and silver star sprinkles while the frosting is still soft.
Storage Tips
To store the finished galaxy cupcakes, place them in an airtight container at room temperature. The cupcakes will maintain their best texture and flavor for up to three days. The frosting forms a slight crust that actually protects the swirled colors, keeping them fresh and visually appealing. Only refrigerate the cupcakes if you are experiencing very hot weather, and be sure to let them come to room temperature before serving for the best taste and texture. Avoid freezing the frosted cupcakes, as the decorations can become damp when thawing, impacting the overall presentation and taste.
For an eye-catching display, arrange the galaxy cupcakes on a black cake stand or serving platter sprinkled with extra edible glitter. Enhance the galactic theme by pairing them with blue or purple punch for coordinated colors. Consider using tiered stands with space-themed decorations like toy rockets and astronauts for children’s parties. Experiment with different color combinations and fillings to create unique galaxy effects, such as night sky or sunset themes. Whether for birthdays, school events, or astronomy club meetings, these cupcakes are sure to bring out childlike joy with their whimsical appearance and magical allure.
Ingredient Substitutions
For the galaxy cupcakes, there are several ingredient substitutions you can make to suit your preferences or dietary restrictions. If you don’t have buttermilk on hand, you can easily make a buttermilk substitute by adding 1 tablespoon of white vinegar or lemon juice to a measuring cup and filling it with milk up to the 1 1/2 cup mark. Let it sit for 5-10 minutes until it curdles slightly, and then it’s ready to use in the recipe.
If you prefer not to use vegetable oil, you can substitute it with an equal amount of melted butter or melted coconut oil for a slightly different flavor profile. Additionally, if you want to make the cupcakes dairy-free, you can use a plant-based milk like almond, soy, or oat milk in place of the buttermilk and use a dairy-free buttercream frosting recipe instead of American or Swiss meringue buttercream.
For the food coloring, if you don’t have gel food coloring on hand, you can use regular liquid food coloring, but you may need to adjust the amount to achieve the desired color intensity without adding too much liquid to the frosting. Start with a small amount and gradually add more until you reach the desired shade. Remember that gel food coloring is recommended for vibrant colors without altering the frosting’s consistency.
Serving Suggestions
Serve these whimsical galaxy cupcakes on a black cake stand or platter sprinkled with extra edible glitter for a stunning presentation. For a children’s party, arrange them on a tiered stand alongside toy rockets and astronauts to enhance the space theme further. Pair them with blue or purple punch for a coordinated color scheme that will delight both kids and adults alike.
Experiment with different color combinations and fillings to create unique galaxy effects. Try deep blue, purple, and silver for a night sky look, or pink, orange, and yellow for a sunset galaxy. During the holidays, red, green, and white will bring a festive cosmic theme to your dessert table. Consider using mini chocolate chips for a “meteor shower” effect or colored sugar crystals for stardust-like embellishments. Let your creativity shine as you explore the galaxy of possibilities with these delightful cupcakes.
