A modern twist on the classic Yule Log (Buche de Noel), this birch bark drip cake combines two of the most popular trends in cake decorating — realistic bark texture and a rich chocolate drip — into one stunning holiday centerpiece. Chef Alan Tetreault of Global Sugar Art walks through every step, from painting the birch pattern on buttercream to piping buttercream pine cones and using silicone molds for lifelike pine branches.
What You'll Need
- Three 6-inch round cake layers — baked in 6-inch pans, leveled to 2-inch layers
- Crusting buttercream — Chef Alan uses his own recipe; a crusting formula is essential for the smoothing and bark techniques
- Quick Icer piping tip (Wilton) — a wide, ridged tip for fast, crumb-free icing application
- Cake smoother — for smoothing the sides and top
- Brown gel food coloring — for painting the birch bark pattern
- Small paintbrush — for applying the food coloring
- Palette knife — for dragging texture into the bark
- Paper towel — for keeping the palette knife clean between strokes
- Silky fudge icing, chocolate ganache, or canned chocolate icing — for the drip; each produces a slightly different drip effect
- Cooling rack — for catching excess drip
- Fondant smoother — for final top smoothing with parchment paper
- Parchment or wax paper — placed between the fondant smoother and buttercream
- Quarter-inch poly dowels — cut to 3–4 inches, used as supports for piping pine cones
- Piping tip 101, 102, or 103 — petal tips for piping pine cone "scales"
- Pastry bag — with brown/chocolate buttercream for pine cones
- Styrofoam block — for drying pine cones upright
- Karen Davies silicone pine branch mold — for molding realistic pine sprigs
- Green gum paste (or 50/50 fondant and gum paste mix) — for the molded branches
- Vegetable shortening (Crisco) — a thin coat helps release detailed pieces from the mold
- Red gum paste — for holly berries; Chef Alan uses Satin Ice gum paste
- Gum glue or tylose glue — for attaching berries and giving them a glossy finish
- Toothpicks — for mounting the berries
- Pre-made gum paste poinsettia — for a finishing accent
- Aluminum foil or food-safe straw — for inserting wired decorations safely into the cake
Icing the Cake with Buttercream
- Stack the three leveled 6-inch layers with buttercream between each one and apply a thin crumb coat.
- Fit a pastry bag with the Wilton Quick Icer tip and pipe buttercream over the entire outside of the cake. This tip lays down icing without dragging crumbs up from the crumb coat the way a spatula can.
- Smooth the sides with a cake smoother, but do not aim for a perfectly smooth finish — a slightly rough surface actually enhances the birch bark look.
💡 Tip: Tall stacked cakes can wobble. Apply even, gentle pressure while smoothing to keep the cake stable.
Creating the Birch Bark Effect
↪ Painting the Bark Lines
- Place a small dot of brown gel food coloring in a dish.
- Dip a small paintbrush in water, pick up a small amount of color, and thin it slightly.
- Paint short, irregular horizontal streaks around the sides of the cake. Vary the length and spacing so they look natural — avoid evenly spaced lines.
- Where there are small divots or gaps in the buttercream, paint an eye shape around them to mimic the knots found on real birch trees.
💡 Tip: Keep the paintbrush fairly wet with food coloring. Working on fresh buttercream causes the brush to drag if it is too dry.
↪ Adding Bark Texture with a Palette Knife
- Dip a palette knife in water.
- Lightly drag it through the buttercream in short strokes — some through the painted color, some through the plain white areas.
- Wipe the palette knife clean on a paper towel between strokes.
- Work around the cake, roughing up the surface to imitate the way birch bark peels and curls away from the tree.
Smoothing the Top
Unlike the sides, the top of the cake needs to be smooth because it will be the base for the chocolate drip.
- Let the crusting buttercream set for a few minutes until it no longer sticks to a light touch.
- Place a piece of parchment paper on top of the cake.
- Use a fondant smoother to gently press and glide over the paper, evening out the surface.
The Chocolate Drip
- Heat the silky fudge icing (or ganache) in the microwave in 5–10 second intervals, stirring between each, until it reaches a pourable but not runny consistency.
- Transfer the cake to a cooling rack set over a sheet pan so excess drips fall through.
- Pour the warm icing onto the center of the top of the cake.
- Use a spoon to gently push the icing toward the edges — once it reaches the rim, gravity pulls it down the sides in natural drips.
- Let the drip set for several minutes before moving the cake to its serving platter.
💡 Tip: Chef Alan notes that fudge icing is thicker and produces shorter, chunkier drips, while chocolate ganache is thinner and drips all the way down the sides. Both look great — choose based on the effect you prefer.
Making Buttercream Pine Cones
- Cut quarter-inch poly dowels into 3–4 inch lengths.
- Fit a pastry bag with a petal tip (101, 102, or 103) and fill with brown or chocolate buttercream.
- Pipe a small dab of icing on the top of the dowel, then pipe three small petals pointing upward to form the tip of the pine cone.
- Move down slightly and pipe a ring of small petals around the dowel — similar to piping a rose, but keeping the diameter consistent instead of widening.
- Continue adding rows of petals down the dowel, maintaining the same width all the way down. This uniform diameter is what distinguishes a pine cone shape from a rose.
- Stand the finished pine cones in a styrofoam block and let them dry overnight at minimum so they firm up enough to handle.
💡 Tip: These can also be made with royal icing for an even firmer result, or piped with crusting buttercream a couple of days in advance. Chef Alan's pre-made pine cones were firm enough to pick up and place after two days of drying.
Molding Pine Branches
- Roll green gum paste (or a 50/50 fondant-gum paste blend) into a small cylinder.
- Apply a very thin coat of vegetable shortening to the gum paste before pressing it into the mold — this prevents delicate details from sticking in the deep cuts of the silicone mold.
- Press the gum paste firmly into the Karen Davies pine branch mold.
- Pop the finished piece out of the mold.
💡 Tip: For molds with very small, deep cuts, a light coating of shortening is more reliable than freezing for clean release.
↪ Making Holly Berries
- Roll small balls of red gum paste (Satin Ice gum paste works well).
- Mount them on toothpicks for easy drying and placement.
- Brush with a thin coat of gum glue to give them a realistic glossy shine.
Assembling the Finished Cake
- Decide which side of the cake will be the front.
- Attach the molded pine branches to one side using a small amount of chocolate buttercream as adhesive. Trim pieces to different lengths for a natural arrangement.
- Insert the dried buttercream pine cones into the arrangement using pliers or tweezers to position them.
- Add the holly berries on toothpicks for pops of color.
- On the opposite side, position a pre-made gum paste poinsettia. Adjust the petals to your liking, and wrap the wires in foil or insert them into a food-safe straw before pushing into the cake so the wires do not touch the food directly.
⚠️ Warning. Always use a barrier (foil, straw, or food-safe pick) between wired decorations and the cake to keep wires from contacting food.
