Imagine capturing his cheeky smile, floppy ears, and sweet personality—without the fuss. Let’s walk through everything from frosting prep to final flair, so you can whip up this cake confidently and creatively.

🎂 What You’ll Need

  • 6″ (or 8″) frosted cake (smooth buttercream or ganache finish)
  • Black piping gel or thick black buttercream
  • Small round piping tip (e.g. Wilton #2 or #3)
  • Edible image, fondant topper, or printed Snoopy silhouette
  • Optional: red fondant collar or speech bubble flair

🧁 Step-by-Step Decoration Tutorial

  1. Prepare Your Cake Canvas
    First off, frost your cake in a base color—white, cream, or light gray looks great! Smooth the surface with a bench scraper and chill for 15 minutes to set.
  2. Transfer the Snoopy Silhouette
    Print a Snoopy outline sized to fit your cake’s top. Lightly press it onto the chilled surface, then use a toothpick to trace the shape and delete the pattern. Remove the paper.
  3. Outline with Black
    Using a small piping tip and thick black frosting or gel, carefully trace the Snoopy silhouette. Aim for clean lines and consistent pressure. The chilled cake helps keep lines sharp!
  4. Fill and Smooth
    Flood the interior with your black icing. Use a toothpick or small spatula to gently smooth and fill gaps. If you're using a fondant or edible topper, gently press it in place here.
  5. Add Facial Features
    Pipe on Snoopy’s eye, nose, collar, and floppy ear detail. Less is more when it comes to expression—keep it sweet and simple!
  6. Finishing Touches
    For a festive vibe, add a red fondant collar, a little speech bubble saying “Happy Birthday!”, or colorful sprinkles around the base.
Pro Tips for a Clean Finish
  1. Chill between stages: Helps lines stay crisp and icing set quickly.
  2. Use stiff frosting: Too runny and it’ll blur. Add a tad more powdered sugar if needed.
  3. Practice piping: Sketch your design on parchment and pipe it for practice before committing to the cake.
  4. Fresh black icing ensures rich contrast—especially against light frosting.
