Space Cake: Toddler Tuesdays

This week my Toddler Tuesdays post is specific to one toddler in particular.   My son is turning 2 this week and I’m having a hard time believing it.   In some ways it feels like he has been with us forever but in other ways I just can’t believe that he is already going to be 2!  It’s true that time flies and you should cherish every minute of it.

Last year we did a Little Blue Truck theme for his party because that was his favorite book.  He still loves those books and we have all 5 of them.  We read at least one of them every single day.  We had a big party and did his baptism at the same time.  You can read more about it in my Little Blue Truck Party Ideas post from last year.

This year we decided to stay low key.  We weren’t going to have a party but since we celebrate all the summer birthdays at my parents house we just decided to have J’s birthday along with the July birthdays.   J is the only person with an August birthday and with school starting I knew it would be a little crazy.  In July we celebrate my dad, my cousin, my husband, and my birthday so one more wasn’t a big deal.

Since we were having a family party I didn’t have a big, blown out theme and we just went with a Space Cake.   J’s room is done is a space theme so I thought it would be fun to make him a space cake as well. He isn’t a huge cake fan so I knew as long as I put my buttercream frosting on top he’d be happy with it.

I made him a basic funfetti cake and put in Outer Space Sprinkles from Sweets & Treats in the batter.  These are black, blue, purple, and silver sprinkles as well as silver stars so I knew that would be a fun base for the cake.   After it baked up I whipped up a batch of buttercream frosting and J happily licked the beaters.  I put 3/4 of the frosting into one pile and dyed it black then divided the remaining frosting and dyed it pink, blue, purple, and white.

I spread a layer of black frosting on the bottom cake layer and topped it with sprinkles then the other cake layer.  I then covered the cake in black.  Once that was finished I dotted on the other colors on top and swirled them in so it totally looked like a galaxy!  This cake looked so much better then I thought it was going to and I was pretty excited about it.

After swirling it around I stuck on some sugar planets and then made constellations on the sides out of sugar pearls.   I actually used a star map so the constellations are real but you could just stick on the pearls to look like random stars. In the end the cake was adorable and it tasted great too.  J enjoyed the frosting and my family really liked it so it was an overall hit.

For the Cake:

  • 2 1/2 c. flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1 teaspoon salt
  • 3 sticks butter 1 cup
  • 1 1/2 c. sugar
  • 4 eggs
  • 1 Tablespoon vanilla
  • 3/4 c. milk
  • 1/2 c. Sweets & Treats Outer Space Sprinkles

For the frosting and decoration:

  • 4 sticks butter 2 cups, softened
  • 6 c. powdered sugar
  • 2-3 Tablespoons milk
  • 1 Tablespoon vanilla
  • Black blue, purple, and pink gel food coloring
  • Sweets and Treats outer Space Sprinkles
  • edible pearls optional
  • sugar planets optional


  • Preheat the oven to 350 degrees.
  • Spray two 8 inch cake pans with baking spray and line the bottom of the pans with parchment paper. Set aside.
  • In a large bowl combine the flour, baking powder, baking soda, and salt. Mix and set aside.
  • In another large bowl cream together the butter and sugar. Add in the eggs and vanilla and mix well.
  • Add half of the flour mixture to the butter mixture and mix until combined.
  • Add the milk to the butter mixture and mix until smooth.
  • Add in the remaining flour mixture and mix until just combined, do not over mix.
  • Fold in the outer space sprinkles. If you don't have these sprinkles mix in a combination of blue, black, silver, and purple sprinkles.
  • Divide the batter between the two prepared pans and put in the oven.
  • Bake for 35-40 minutes or until a toothpick inserted into the center comes out clean. Remove from oven and cool 10 minutes. Run a butter knife around the edges and remove the cakes from the pans. Cool completely on wire racks.
  • To make the frosting place the butter in a large bowl. Beat with a mixer until smooth.
  • Add in the powdered sugar a cup at a time until the mixture is smooth.
  • Add in the milk and vanilla and mix until smooth.
  • Remove 1 cup of frosting and divide between 4 bowls.
  • Color the large portion of frosting black. In each of the 4 small bowls of frosting color one blue, one purple, one pink, and leave one white.
  • Place one cake on a cake round. Place 1 cup of black frosting on top of it and smooth it out. Place the second layer of cake on top of the first layer. Cover the cake with black frosting.
  • Take small teaspoons of each of the blue, purple, pink, and white frostings and dot them all over the top of the cake. Carefully use a butter knife and swirl the colors into the black frosting to create a fun galaxy look. Use more of the colored frosting if you want a brighter galaxy.
  • Press the sugared planets into the sides of the cake and put a few on top.
  • Press 1/4 cup of outer space sprinkles around the bottom of the cake.
  • Place the edible pearls on the sides of the cake, in between the planets, in the shape of constellations.
  • Write on top of the cake if desired and enjoy!
