Spicy Chocolate Cake with Chili and Passionfruit Drizzle

Chocolate passionfruit layer cake

Whether you’re hosting a special dinner or simply want a cake with bold character, this Chocolate Cake with Chili & Passionfruit delivers. It combines deep dark chocolate, bright passionfruit, and a subtle chili-ginger warmth in a dramatic six-layer dessert. The result is sweet, tangy, spicy, and intensely chocolatey — a show-stopping cake for anyone who loves adventurous flavors.

This flavor trio is one of my favorites: the tartness of passionfruit, the silk of chocolate ganache, and the gentle heat from chili and ginger. The passionfruit-ginger curd brings freshness, the chili-ginger ganache adds complexity, and the moist devil’s food crumb ties everything together.

This recipe is a bit involved, but the layered textures and striking contrast of flavors make the effort worthwhile.

Quick overview: how to make this cake

See the recipe card below for exact measurements and full details.

Chocolate cake layers

  1. Prep pans & oven: Butter three 6″ cake pans, line bottoms with parchment, and preheat the oven to 350°F (180°C).
  2. Dry ingredients: Whisk together flour, baking soda, baking powder, and salt.
  3. Chocolate base: Melt bittersweet chocolate with cocoa powder, instant coffee (optional), and boiling water until smooth.
  4. Cream butter and sugar: Beat softened butter and brown sugar until fluffy, then add eggs one at a time. Mix in sour cream and vanilla.
  5. Combine & bake: Add dry ingredients, then slowly pour in the chocolate mixture while mixing. Divide batter evenly among pans and bake. Cool completely.

Passionfruit ginger curd

  1. Whisk: Combine passionfruit purée, lime juice, grated ginger, egg yolks, sugar, and salt.
  2. Cook gently: Set the bowl over simmering water and whisk until the curd coats the back of a spoon, then whisk in butter.
  3. Strain & chill: Push the curd through a fine sieve, cover the surface with plastic wrap to prevent a skin, and chill until cool.

Chili ginger ganache

  1. Infuse cream: Warm heavy cream with crushed chili, sliced ginger, and a pinch of salt until bubbles form at the edges.
  2. Make ganache: Pour the hot cream over finely chopped chocolate, let it sit briefly, then whisk from the center outward until smooth. Remove solids.
  3. Cool: Let the ganache cool slightly before using so it’s pourable but not thin.

Assembling the cake

  1. Slice layers: Trim each cooled cake horizontally to create six even layers.
  2. Layer: Alternate a thin layer of passionfruit curd and a thin layer of ganache between cake rounds, beginning with curd and ending with cake.
  3. Finish: Chill briefly, apply a thin ganache crumb coat, chill again, then pour the remaining ganache over the top so it drips slightly down the sides. Decorate to taste.

Tips for perfect passionfruit curd

  • Gentle heat: Use a double boiler to cook the curd slowly so the eggs don’t scramble.
  • Doneness check: It’s ready when it coats the back of a spoon or reaches about 170–175°F (77–80°C); it will thicken further as it cools.
  • Strain: Passing the curd through a fine sieve removes fibers and yields a silky texture.
  • Avoid skin: Press plastic wrap directly onto the surface while cooling to prevent a skin from forming.

Troubleshooting ganache

Up close silky texture of chocolate chili ganache

Chocolate can be temperamental, so these fixes help when ganache misbehaves:

Grainy or seized ganache: Warm the cream gently and avoid boiling. Whisk slowly from the center outward when combining. If the ganache splits, whisk in a teaspoon or two of cold heavy cream to bring it back together.

Too thick: Gently warm the ganache (preferably over a double boiler) and whisk until pourable again.

Too thin or runs off the cake: Let the ganache cool to room temperature before pouring so it drips elegantly rather than running away.

Ingredients

 

Devil’s Food Cake

  • 1 1/2 cups flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1 1/4 cup boiling water
  • 4 ounces bittersweet chocolate, chopped fine
  • 1/2 cup natural cocoa powder
  • 1 teaspoon instant coffee, (optional)
  • 5 ounces unsalted butter, soft
  • 1 1/4 cup brown sugar
  • 3 eggs, room temperature
  • 1/2 cup sour cream
  • 1 teaspoon vanilla

Ginger Passionfruit Curd

  • 3/4 cup passionfruit purée
  • 1/4 cup fresh lime juice
  • 1 teaspoon fresh ginger, grated
  • 4 egg yolks
  • 1/4 cup sugar
  • 1/4 teaspoon salt
  • 2 ounces unsalted butter, cubed

Chocolate Chili Ganache

  • 8 ounces semisweet or dark chocolate, chopped fine
  • 6 ounces heavy cream
  • A pinch of salt
  • 1 hot chili pepper, seeded
  • 1 1-inch chunk of fresh ginger

Instructions

 

For the devil’s food cake:

  • Butter three 6-inch cake pans and line with parchment paper. Preheat oven to 350°F (175°C).
  • Whisk dry ingredients (flour, baking soda, baking powder, and salt) together in a bowl.
  • Whisk chopped chocolate, cocoa powder, instant coffee, and boiling water in a heatproof bowl until smooth and fully combined.
  • Cream butter and brown sugar with a mixer fitted with the paddle attachment until light and fluffy, about 3 minutes.
  • Add eggs one at a time, beating until incorporated.
  • Stir in sour cream and vanilla until combined.
  • Add dry ingredients and blend just until combined. With the mixer running, gradually pour in the chocolate mixture, stopping to scrape the bowl as needed. Blend until just combined.
  • Divide batter among pans and bake until the center springs back when touched, about 32–35 minutes. Cool completely before assembling.

For the ginger passionfruit curd:

  • Combine passionfruit purée, lime juice, grated ginger, egg yolks, sugar, and salt in a metal or glass bowl. Place the bowl over a pot with an inch or two of simmering water — the bowl should not touch the water.
  • Whisk frequently over medium heat until the mixture thickens and coats the back of a spoon, about 8–12 minutes.
  • Remove from heat and whisk in the butter until smooth.
  • Strain through a fine-mesh sieve into a clean bowl, press plastic wrap onto the surface to prevent a skin, and chill until completely cool.

For the chocolate chili ganache:

  • Lightly crush the chili pepper and ginger. Add them and a pinch of salt to heavy cream in a small saucepan and heat on low.
  • Place finely chopped chocolate in a bowl and have it ready.
  • Heat the cream until the edges form small bubbles; do not boil, which can cause separation.
  • Pour the warm cream over the chocolate, let sit for a minute, then whisk gently from the center outward until a thick, silky ganache forms. Remove the chili and ginger pieces.

To assemble cake:

  • When cakes are cool, remove from pans and peel off parchment. Slice each cake in half horizontally to make six layers.
  • Place the bottom round on a serving plate and spread a thin layer of passionfruit curd, leaving a small border. Top with the next cake layer and press gently to adhere.
  • Spread a thin layer of ganache on the next layer, leaving a border, then stack the next cake layer on top.
  • Alternate curd and ganache until all layers are used; you should have three layers of curd and two of ganache between the cake rounds.
  • Top with the final cake layer, chill the assembled cake for 20–30 minutes, then apply a thin ganache crumb coat and chill again.
  • Warm the remaining ganache gently if needed so it is pourable. Pour it over the chilled cake and tilt slightly to encourage small drips down the sides.
  • Decorate as you like, slice, and serve. Store the cake in the refrigerator between servings and enjoy within three days.

Notes

Keep the cake refrigerated between servings. Best eaten within three days for peak texture and flavor.
