Flourless Chocolate Cake with Kahlúa & Espresso

Flourless Chocolate Cake with Kahlúa & Espresso is a decadent, naturally gluten-free dessert baked in individual ramekins. Each one is oozing with melting dark chocolate, scented with espresso, and the subtle taste of Kahlúa.

Ever had a flourless chocolate cake? 

How about a chocolate Kahlúa cake?

Or a chocolate espresso cake? 

OR . . . . wait for it . . . . how about the mother of all of these luscious desserts, a Flourless Chocolate Cake with Kahlúa & Espresso?

I have been serving this rich dessert for years and serious chocolate lovers always have the same reaction to it: they take a bite, close their eyes, and let out a quiet moan.

This is also my favorite type of gluten-free dessert - one that's inherently gluten-free, where no substitutions are needed.

Ingredient Notes

• Bittersweet chocolate - This is the star, so it’s worth buying a high-quality chocolate. I like this one, and if you prefer semisweet, use it. I don't recommend using chocolate chips, which are made to hold their shape and don’t melt as silkily.
• Unsalted butter - It makes the cakes rich and gives the center its fudgy texture. Unsalted lets you control the salt. You’ll also use a little to grease the ramekins.
• Instant espresso powder - The espresso enhances and deepens the chocolate flavor so the cakes taste more chocolatey, not like coffee. Look for “instant espresso powder” on the label, and not regular instant coffee, which is milder.
• Kahlúa - The coffee liqueur adds a subtle sweetness and a warm roasted flavor. You only need 3 tablespoons, so it’s a gentle hint, not too boozy.
• Pure vanilla extract - It rounds out the chocolate and coffee. Choose pure extract over imitation.
• Large eggs and egg yolks - The whole eggs give the cakes structure so they rise, and the extra yolks add richness and that creamy center.
• Cocoa powder - It adds depth and helps the cakes set. (Be sure it's unsweetened!)
• Granulated sugar - It sweetens the batter, and a dusting inside the buttered ramekins gives the cakes a delicate edge and helps them rise and release. Coat the ramekins all the way up the sides.
• Powdered sugar - A light dusting at the end makes the cakes look finished.

How to Make Individual Flourless Chocolate Cakes

- Preheat the oven to 425°F and adjust a rack to the center. Add about 2 inches of water to a baking dish that's approximately 9 x 13 inches, and place it in the oven while it preheats.

- Use the 2 teaspoons of the butter to grease 6 (4-ounce) ramekins. Then dust them with 2 tablespoons of granulated sugar. Be sure the entire inside is well coated because the cakes might rise in the oven.

Recipe Tip: Do not expect these to rise like a soufflé. They'll rise a bit, but not too much.

- Add the remaining ½ cup of butter and the chopped chocolate to a small saucepan. Place it over very low heat and melt the two together. Once it's nicely blended, remove the pan from the heat and add the espresso powder, Kahlúa and vanilla. Set aside to cool.

- In a medium-sized mixing bowl, whisk the eggs and egg yolks for about 1 minute. Once they are a bit frothy and slightly lighter in color, add the remaining tablespoon of sugar and whisk for another minute. They'll be even lighter and frothier.

- Pour in about half of the cooled chocolate mixture and mix just for a moment. Then add the remainder of it, along with the cocoa powder and mix to blend.

- Divide the batter evenly among the 6 prepared ramekins and very carefully place them into the baking pan that's already in the oven with the water. (The water should go a bit less than halfway up the sides of the ramekins, and anywhere near that is okay.) Bake in the preheated 425°F oven just until they look almost dry on top, 8 to 10 minutes. You want them to be a bit wet in the middle.

- Let them sit in the ramekins for 5 to 10 minutes, then run a dull knife along the edges in case they need to be loosened. You can serve them in the ramekins or inverted onto dessert plates. Let them cool slightly, sprinkle with powdered sugar and serve.

Recipe Tip: If you let them sit longer than 5 to 10 minutes, they won't be as easy to invert.

Serving Suggestions

• Vanilla bean ice cream - This cake is especially delicious with a small scoop of vanilla bean ice cream. When the dessert is warm, the ice cream will melt a bit to make a sauce.
• Vanilla crème anglaise - Drizzle it over the top or on the side of the cakes. The silky vanilla custard balances the bittersweet chocolate and Kahlúa.

Can you make it ahead?

• I think the cakes are best served about 10 minutes after they're removed from the oven. (They cool for 5 to 10 minutes in the ramekins, and can then be inverted onto dessert plates.)
• You can make them up to 3 hours ahead. I'd keep them in the ramekins to serve, and warm them a few minutes before in either a 400°F oven for a couple of minutes, or the microwave for about 30 seconds or less.

Did I mention how incredibly impressive this is to serve at a dinner party!?
