What we love about this decadent low FODMAP & gluten free flourless chocolate recipe
When you're following the low FODMAP diet, finding a bakery-quality cake that doesn't rely on high-fructan wheat or gritty flour substitutes can be a challenge. This Flourless Chocolate Cake is a ‘go to’ decadent treat. It relies on the structure of eggs and high-quality dark chocolate to create a dense, truffle-like texture that is naturally gluten-free. It’s an elegant, mouth-watering dessert that is perfect for dinner parties or a weekend treat.
Dietitian Approved: This recipe is from the IBS Coach: FODMAP Diet Plan app. The beginner friendly, complete fodmap plan to feel good again. We highly recommend it.
Five-Minute Prep: Aside from the baking time, the batter comes together in a single pot. It’s an incredibly simple, "one-bowl" style method that yields professional results every time.
Why it’s an IBS Friendly Recipe
Naturally Flourless: By omitting flour entirely, we eliminate wheat fructans. This makes the cake lighter on the digestive system and 100% gluten-free without needing expensive specialty flours.
Low Lactose Fats: Butter is used for richness, but because it is almost entirely fat, it contains negligible amounts of lactose, making it a "green light" ingredient for most people with IBS.
70% Dark Chocolate: High-cocoa chocolate is lower in sugar and dairy than milk chocolate. In a shared cake format, the serving size remains well within the safe FODMAP thresholds.
Simple Ingredients: No artificial sweeteners or polyols (like xylitol or erythritol) which are common "hidden" triggers in many commercial sugar-free or gluten-free desserts.
Flourless Chocolate Cake Low FODMAP Ingredients
Serves: 8-10
Total Time: 40 minutes
Difficulty: Easy
- 100g Dark Chocolate (70% cocoa)
- 100g Butter
- 175g Sugar
- 3 Large Eggs
- 3 tbsp Cocoa Powder
- 1 tsp Vanilla Essence
Step By Step Instructions
1. Preheat your oven to 190°C (170°C Fan / 375°F / Gas 5).
2. Rub a small amount of butter over the base and sides of an 8-inch round baking tin. Add one teaspoon of cocoa powder and rotate the tin to coat the surfaces. Tap out any excess. This creates a delicious, dark crust.
3. Break or chop the dark chocolate into small, uniform pieces to ensure it melts smoothly.
4. Add the butter, sugar, and vanilla essence to a medium pot. Melt gently over medium heat, stirring until the mixture is combined.
5. Once the butter is melted, remove the pot from the heat. Add the chopped chocolate and stir until completely melted and glossy.
6. Whisk in the eggs one at a time, ensuring each is fully incorporated before adding the next. This creates the "lift" and structure of the cake.
7. Pour the batter into your cocoa-dusted tin. Bake for 25 minutes until the top has set and formed a delicate crust, but the centre still has a very slight "give."
8. Leave the cake to cool in the tin for at least 5 minutes before serving. This is a mechanical necessity—the cake "firms up" as it cools.
