Instructions
Letโs jump into creating these galaxy-inspired beauties!
Step 1: Bake the Cupcakes
Preheat your oven to 350ยฐF (175ยฐC) and line a cupcake pan with paper liners. In a large bowl, mix the flour, cocoa powder, baking powder, baking soda, and salt together. In a separate bowl, cream the butter and sugar until light and fluffy. Add the eggs one at a time, mixing in the vanilla extract. Gradually add the dry ingredients into the wet ingredients, alternating with the milk, and mix until just combined. Finally, stir in the boiling waterโthis will thin out the batter and make it nice and moist.
Spoon the batter into the cupcake liners, filling them about 2/3 of the way full. Bake for about 18-22 minutes or until a toothpick comes out clean. Let them cool completely before filling and frosting.
Step 2: Fill with Caramel
Once the cupcakes have cooled, use a small knife or cupcake corer to make a hole in the center of each cupcake. Fill each hole with a generous amount of caramel sauce. You can use store-bought caramel or make your ownโjust make sure itโs gooey and delicious!
Step 3: Prepare the Galaxy Frosting
In a large mixing bowl, cream the butter until soft and smooth. Gradually add the powdered sugar, vanilla extract, and a splash of milk or heavy cream until you reach a smooth, spreadable consistency. Divide the frosting into three bowls and color each one with a different shade of food coloring: blue, purple, and black. Leave a little bit of white frosting for the โstarsโ and to mix in with the other colors.
Step 4: Swirl the Frosting
Now for the fun partโswirling! Using a piping bag with a star tip or just a regular piping bag, pipe the blue, purple, and black frosting onto each cupcake in swirls. Donโt worry about making them perfectโthis is what gives the cupcakes that beautiful, galaxy effect.
Step 5: Add the Finishing Touches
For that final touch of magic, sprinkle a few star sprinkles, or a little edible glitter, to make your cupcakes sparkle like the night sky.
Step 6: Serve and Enjoy!
Serve your Milky Way Galaxy Cupcakes at your next celebration, or simply indulge in the beauty and flavor of the galaxy in the comfort of your own kitchen!

Additional Tips
