Step-by-Step Instructions
1. Bake the Cupcakes
-
Preheat oven to 350°F (175°C). Line a 12-cup muffin pan with liners.
-
In a bowl, whisk together sugar, melted butter, and eggs until well combined. Mix in vanilla.
-
In a second bowl, whisk flour, baking powder, and salt. Add to wet ingredients alternately with milk, mixing just until smooth.
-
Divide batter evenly among liners (about ⅔ full). Bake 18–22 minutes or until a toothpick comes out clean. Cool completely on a wire rack.
2. Make the “Sand”
-
Crush graham crackers or golden Oreos in a zip bag with a rolling pin until fine.
3. Prepare Octopus Decorations
-
Marshmallow Heads: Melt candy melts (or white chocolate with food coloring) in a small bowl per package instructions. Skewer each marshmallow with a toothpick (for dipping handle).
-
Dip marshmallow in candy melts, covering fully. Set on parchment. Before coating sets, press on two candy eyes and one small candy “nose” (optional).
-
Allow to set completely (5–10 min). For extra sparkle, sprinkle with sanding sugar before the coating hardens.
-
Tentacles: Using kitchen scissors, cut Sour Punch Bites or Twizzlers in half lengthwise if needed, to create thin strips. You’ll need 6–8 per cupcake.
4. Frost & Decorate Cupcakes
-
Spread a generous layer of frosting on each cupcake. Sprinkle with crushed “sand.”
-
Gently stick 6–8 tentacle candies into the center of each cupcake so they fan out over the sides.
-
Place the marshmallow octopus head on top, anchoring over the tentacle ends (use a dab of frosting as “glue” if needed).
-
Pro tip: If tentacles slide, poke a shallow hole in the cupcake/frosting to anchor candy. Press marshmallow down gently.
5. Final Touches
-
Add extra sprinkles or a light sprinkle of blue sanding sugar for a “water” effect.
-
If transporting, store cupcakes in a deep container with a lid. If making ahead, add marshmallow heads just before serving to keep decorations fresh.
Tips for Perfect Results
-
For vibrant heads, use bright colored candy melts or tint white chocolate with oil-based food color.
-
If candy melts are too thick for dipping, add ½ teaspoon coconut oil to thin.
-
Use different flavors of candy for tentacles—sour, sweet, or fruity!
-
Want extra flavor? Swirl a bit of citrus zest or coconut into the cupcake batter.
Serving Suggestions
-
Arrange cupcakes on a platter sprinkled with extra “sand” and a few gummy fish for an undersea look.
-
Perfect for birthdays, pool parties, or ocean-themed celebrations.
-
Remove toothpicks before serving to small children.
Storage
-
Store decorated cupcakes in an airtight container at room temp for up to 24 hours, or refrigerate (covered) up to 3 days.
-
To freeze: Freeze un-decorated cupcakes up to 2 months. Add marshmallow heads and tentacles after thawing for best appearance.
-
Avoid direct sun/heat to keep decorations intact.
