A realistic two-tier square Roblox birthday cake in vibrant red frosting, featuring edible circular studs on top and white marshmallow details, decorated with Roblox-style character figurines and edible silver coinsThe Ultimate Roblox “Blox” Celebration Cake

  • Prep time: 50 mins

  • Bake time: 30 mins

  • Level: Easy (Uses the “Marshmallow Stud” hack)

### Ingredients

For the Cake Base:

  • 2 boxes of Red Velvet or Vanilla Cake Mix

  • White Chocolate Chips (folded into the batter for a “premium” feel)

For the “Roblox Red” Buttercream:

  • 1 kg Vanilla Buttercream

  • Deep Red food coloring (Gel works best for that bold Roblox look)

  • 1 bag of Large Marshmallows (This is your secret weapon for the studs!)

For the Decorations:

  • White Fondant or White Chocolate (to cut out the “R” logo)

  • Roblox Avatar toppers or toy figurines


### Step-by-Step Instructions

1. Constructing the Base

  • Bake your cakes in two square pans (standard 20cm).

  • Once cooled, stack them with a thick layer of frosting in between.

  • Square it off: Use a serrated knife to ensure the sides are perfectly vertical. Roblox is all about sharp, clean angles!

2. The Iconic Studs (The Hack)

  • Take your large marshmallows and snip them in half horizontally using clean kitchen scissors.

  • Place these halves, cut-side down, in a perfect grid pattern (3×3 or 4×4) on the top of your cake. These will act as the “studs” found on top of every Roblox block.

3. The “Red Blox” Coating

  • Apply a crumb coat of red frosting and chill for 20 minutes.

  • The Final Pour: For a super smooth look, you can slightly warm your buttercream (or use a red chocolate ganache) and pour it over the cake, ensuring it covers the marshmallow studs completely.

  • Alternatively, pipe the frosting over the marshmallows and smooth it out with a warm palette knife. The result should look like a molded plastic brick.

4. Branding the Block

  • Roll out a small piece of white fondant and cut out the iconic “chewed square” Roblox logo (a square with a smaller square cut out of the center).

  • Press this onto the front face of the cake.

5. Level Up

  • Place your child’s favorite Roblox figurines on the top or around the base.

  • Add some silver edible glitter to represent “Robux” scattered around the plate.
