🍀 Are you ready to add a touch of luck to your St. Patrick's Day celebrations? Dive into the world of cookie decorating with our fun and festive decorating kit! This kit is designed to make your cookies stand out with adorable shamrock glasses and "Lucky" text designs. Whether you're a beginner or a seasoned decorator, this kit offers two exciting decorating pathways to explore. 🌈
What’s in Your St. Patrick's Day Decorating Kit
This kit comes with:
-
A cookie cutter for shamrock glasses (approx 2¼″ h × 3¼″ w) and matching stencil.
-
A cookie cutter for a 4″ w × 4½″ h shamrock, and “Shamrock Shower” all-over background stencil (5″×5″) that can be cropped onto the Shamrock cookie.
- All stencil sheets fit within a standard Stencil Genie.

Whether you’re a beginner or an advanced decorator, you’ll find both techniques laid out here — choose the technique that fits your setup (or mix both for a hybrid look!).
Materials & Preparation
You’ll need (for either method):
-
Sugar cookie dough, rolled and cut using the provided cutters (shamrock glasses & shamrock). Need a cookie recipe? Try using our Ultimate Sugar Cookie Recipe!
-
Bake your cookies, let them cool completely before decorating.
-
The included stencils from the kit.
-
A clean workspace, parchment or silicone mat, etc.
For Royal Icing path:
-
Royal icing (prepared to the right consistency)
-
Gel colorants (Grass Green, Lime Green)
-
Smooth/scrape tool (e.g., Icing Genie or stencil scrapers)
-
Squeeze bottles or piping bags for detail if desired.
- Stencil Genie to hold stencil in place (optional, but does offer more professional results).
For Airbrushing path:
-
Airbrush color, e.g., Emerald Green (or mix with a little black for a deeper tone)
-
Stencil Genie and a Screen Genie to hold stencil in place (both are optional, but does offer more professional results).
-
Masking tools if you want multi-colour layering, etc.
Prep tip: Place a piece of parchment or acetate behind your stencil to catch overspray or excess icing. Work on a flat surface at eye-level for best results.
Technique A: Royal Icing Application
Step 1: Prepare Your Base
- Flood your cookie with background colour if you like (e.g., white or light green). Let it fully set (ideally 12-24 hours for a hard surface).
- Ensure the surface is smooth and level — the stencil works best on a flat, set surface.
Step 2: Place the Stencil
- Position the stencil over your cookie — for example, align the glasses stencil so that it is centered onto the matching cutter.
- Secure the stencil — if not using a holder, you might lightly tape or hold the stencil down with a skewer to avoid shifting.
Step 3: Apply Royal Icing through the Stencil
- Mix your royal icing to a medium consistency (not too runny, but still fluid enough to smooth).
- Colour it using gel colours: for example Grass Green for the shamrock glasses, Lime Green for highlights.
- Apply the icing onto the stencil area with a offset or a small rubber spatula.
- Using a scraper (Icing Genie or similar), gently draw across the stencil in one direction to level the icing with the stencil surface. The kit emphasises working in one fluid motion.
- Lift the stencil carefully straight up to avoid smudging.
- Allow icing to set — depending on thickness, 1-2 hours or more until firm.
Step 4: Add Details
- Once the stencil layer is set, you can pipe fine details: e.g., outlines in darker green, white highlights, little “Lucky” text if included.
- For the shamrock background cookie, you might use a contrasting shade or metallic gold accents for extra flair.
- Let everything fully dry before packaging or stacking.
Tips & Troubleshooting
-
If the stencil shifts, the design lines blur. Use low-tack tape or hold corners.
-
If icing is too thick it won’t level smoothly; too thin and it may bleed under the stencil. Test on a scrap first.
-
Clean the stencil between uses — residual icing can cause gaps or smears.
Technique B: Airbrushing Application
Step 1: Base Cookie Preparation
- Similar to royal icing: have your cookie baked and completely cooled.
- You can choose to either leave the surface bare (rolled dough baked) or apply a thin flood of white icing to create a crisp canvas. Let it fully dry.
Step 2: Position the Stencil & Mask
- Place your stencil carefully. Secure it flat.
- If you want multi-colour (e.g., glasses frame green, lenses gold, shamrock background a lighter green), you may need to mask parts of the stencil or use additional masking sheets.
- Place a piece of cardboard or acetate behind the stencil to protect your workspace.
Step 3: Airbrush Colour
- Use your food-safe airbrush with your chosen colours (the kit suggests Emerald Green for the main motif).
- Start at a distance of about 4-6 inches (10-15cm) from the cookie.
- Spray in light, even passes across the stencil area. It’s better to do several light passes than one heavy one (to avoid overspray and run).
- For deeper colour, you can apply a second pass after the first dries briefly.
Step 4: Remove Stencil & Optional Accents
- Carefully remove the stencil. The design should appear crisp.
- You might then use piping gel or a fine brush of edible gold paint to accent details (e.g., shamrock veins, glasses temples, “Lucky”).
- If you applied a full background (shamrock shower stencil), you might then fill the glasses area with a contrasting colour or metallic sheen.
Tips & Troubleshooting
-
Overspray: keep extra stencil or masking behind the cookie to protect surroundings.
-
Uneven coverage: check your air pressure and distance; heavy centres may mean you were too close.
-
Smudges: ensure stencil is flat; edges must lie flush.
-
Blend colours: you can mask part of the design and spray one colour, then change colour and spray another for layered effects.
Hybrid Ideas
Why choose one when you can combine both techniques? Here are a few fun mash-ups:
-
Use royal icing to pipe and fill the glasses frames in green, let set; then overlay the stencil and airbrush a lighter green into the lenses for a “glass” effect.
-
Airbrush the shamrock-shower background stencil in a subtle mint green, then pipe the shamrock cutter cookie in bold green icing on top.
-
For “Lucky” text: stencil with airbrush in a metallic green or gold, then outline with fine white royal icing.
Final Presentation & Packaging
-
Once fully dry (preferably overnight for icing), you can stack cookies into cellophane bags, add a ribbon (emerald green or gold) and tag them “ShamROCK your St. Patty’s”.
-
Use your cutter shape (shamrock glasses) as a fun conversation piece.
-
These make great treats for school parties, friends, family gatherings (text from kit: “perfect for school parties, friends & family”).
