Turn a small round cake into a watermelon-inspired character with green stripes, a pink top and a cheerful frog face. This Kumora guide interprets the reference image; it does not claim to reproduce the original creator’s recipe or methods.

A little preparation

Before you start

  • Small round cake with a firm base coat
  • Light and dark green plus pink buttercream
  • Fine piping tips and small offset spatula
  • Edible modeled or piped eye shapes
  • Paper face template
01

Separate rind, fruit and face

Plan the side as a green rind and the top as pink fruit. The character details should sit where the front of the cake will be presented. Mark that front on the board before frosting so the stripes and face align.

Use a light green base with a darker green for irregular vertical stripes. Choose a soft pink that remains distinct from the green. A few colors are enough; extra bright accents can distract from the frog expression.

02

Make irregular rind stripes

Smooth the side coating and let it firm enough to take an added color. Apply narrow darker green strokes from top toward bottom, varying the edges slightly. Watermelon stripes need not be mechanically identical.

Keep the strokes relatively thin. If the dark color drags the base with it, chill again and use a lighter touch. Finish the top in pink, leaving a small green edge visible so the fruit illusion reads clearly from above.

03

Build the expression

Add two compact raised eye shapes near the front edge, keeping their bases broad and secure. Mark the pupils before piping them, and check from the intended viewing angle. Small changes in spacing can make the face look very different.

Pipe a short smile and a few seed-like details in the pink area. Keep the eyes and mouth readable rather than covering the entire top with seeds. Use edible materials throughout where possible and avoid hidden sharp supports.

04

Choose one small top accent

A tiny fruit-shaped decoration or a single cake candle can finish the design. The reference’s playful accent is inspiration; you do not need to reproduce every detail. Keep the tallest feature within the box clearance.

Put the longer birthday greeting on the board if the face already fills the top. Store according to the cake and filling used, and carry level. This guide describes the visible decoration without claiming to identify the original cake’s flavor.

From the notebook

The little details

  • Check the face from the front, not only while looking down at the turntable.
  • Dark green stripes should vary in width but remain similar in overall direction.

Your questions, answered

Does the cake need to taste like watermelon?

No. This is a visual theme. Use a cake flavor you trust and describe it accurately rather than implying fruit flavor from the colors.

Can I make the eyes flat?

Yes. Flat piped eyes are easier to transport and can retain the same expression.
