This flourless mint chocolate cake blends ultra-rich, fudgy chocolate with a silky white-chocolate mint center and a glossy dark ganache. It’s an elegant, small-batch showstopper perfect for holiday tables or any time you crave an intense chocolate experience.
What makes this flourless mint chocolate cake special
Unlike traditional cakes, this one contains no flour. The texture comes from melted chocolate, eggs, butter, sugar and cocoa. The result is dense, molten, and deeply chocolatey.
Expect a luxurious mouthfeel that’s closer to a torte than a sponge. A shallow depression in the baked cake is intentional — it becomes the perfect cavity for the minty filling.
Ingredients for cake, filling and ganache
Gather quality chocolate for best results. Finely chop before melting to help the chocolate become smooth quickly.

Step-by-step method to bake and assemble
Read through each component before you begin. Timing is important, especially to achieve the desired sinking center.
Prepare the cake
- Preheat oven to 350°F and position a rack in the center.
- Butter a 9 x 2-inch round pan. Line the bottom with parchment and butter it.
- Dust the pan with sifted cocoa powder, tapping away the excess.
- Melt chopped semi-sweet chocolate and butter together in a heatproof bowl.
- Let the mixture cool slightly while you whip the eggs and sugar.
- Beat eggs, sugar, vanilla and salt until pale and fluffy, about double in volume.
- With the mixer on low, pour in the melted chocolate and blend gently.
- Fold in the sifted cocoa until just combined.
- Transfer batter to the prepared pan and bake ~30 minutes.
- The cake should still have a few moist crumbs on a tester. Do not overbake.
- Cool in the pan on a rack for 30 minutes so the center can sink.
- If the cake does not develop a natural cavity, cover it and press lightly with a similarly sized pan to form a dent.
- Run a thin knife around the edge and transfer the cake to a serving plate to finish cooling.
Make the white chocolate mint filling
- Place finely chopped white chocolate in a bowl.
- Heat heavy cream with corn syrup until it reaches a gentle boil.
- Pour the hot cream over the chocolate and let sit 1–2 minutes.
- Stir until smooth, then blend in softened butter and mint extract.
- Add a drop or two of green food coloring if you want that classic mint hue.
- Pour the filling into the cake’s indentation and freeze 10–15 minutes to set.
Finish with chocolate ganache
- Place chopped semi-sweet chocolate in a heatproof bowl.
- Bring heavy cream and corn syrup just to a boil.
- Pour it over the chocolate and let rest a few minutes.
- Stir until glossy and smooth. Cool slightly if too thin.
- Pour ganache over the chilled cake, smoothing across the top and letting it drip over the sides.
- Garnish with fresh mint leaves or festive sprinkles, if desired.
- Chill in the refrigerator to set the ganache before serving.
Key tips for silky ganache and flawless results
- Chop chocolate very finely. Small pieces melt faster and yield a silkier ganache.
- Temper the temperature of hot cream and chocolate. Too hot makes a thin ganache.
- Beat eggs and sugar thoroughly. The extra volume helps the cake rise and then settle correctly.
- Use high-quality chocolate for both filling and topping. Flavor and texture depend on it.
- Slice thin portions. This cake is intensely rich, so a small serving is satisfying.
Storage, serving ideas and holiday uses
Store this cake covered in the fridge for up to five days. Bring to room temperature for 15–20 minutes before serving for the best texture.
- Serve with lightly whipped cream or a scoop of vanilla ice cream.
- Decorate with crushed candy canes at holiday time for a festive crunch.
- Offer thin slices at dinner parties; the richness makes it ideal for sharing.
