As a Registered Dietitian Nutritionist, I have designed this brownie recipe to fit within Monash University low FODMAP portion guidelines. Here is the ingredient-by-ingredient breakdown:

• Gluten-Free Flour Blend: Choose a rice, tapioca, or maize-based blend. Avoid blends containing inulin, chicory root, apple flour, coconut flour (limit), or soy flour, which are high in FODMAPs.
• Dark Chocolate (70% cacao): Monash lists 30 g as a low FODMAP serve. One brownie (from a 12-cut pan) contains around 12 g of dark chocolate, well within the safe range.
• Cocoa Powder: 8 g per serve is low FODMAP. This recipe uses about 2 g per brownie.
• Butter: Butter is virtually lactose-free and low FODMAP in typical serves. If highly sensitive, swap for a lactose-free spread.
• Lactose-Free / Almond Milk: Both are low FODMAP up to 1 cup. Regular cow's milk should be avoided.
• Sugar: Sucrose is low FODMAP. Do NOT substitute honey, agave, or high-fructose sweeteners.
• Eggs: Free from FODMAPs.

Serving Advice: Stick to 1 brownie per serve during the elimination phase. Two brownies at once may stack FODMAPs, especially from cocoa and dark chocolate. Always consult your dietitian about your individual tolerance.

Practical Low FODMAP Notes for Low FODMAP Brownies (Fudgy & Gut-Friendly)

Low FODMAP Brownies (Fudgy & Gut-Friendly) is most useful when the serving size stays consistent, because FODMAP tolerance often changes when portions creep upward. Use the listed servings as the starting point, then portion leftovers before storing so the meal stays predictable on busier days. If you are cooking for family members who do not follow a low FODMAP plan, keep onion, garlic, wheat-heavy sides, and high-FODMAP sauces separate at the table instead of mixing them into the main recipe.

Ingredient notes: this recipe uses 1/2 cup (113 g) unsalted butter (lactose-free spread if sensitive), 150 g dark chocolate (70% cacao, dairy-free), 3/4 cup (150 g) granulated sugar, 2 large eggs, room temperature, 1 tsp pure vanilla extract, 1/2 cup (65 g) gluten-free plain flour blend (rice/tapioca base, no inulin or apple flour), 1/4 cup (25 g) unsweetened cocoa powder, 1/4 tsp fine sea salt, 1/4 tsp baking powder, 2 tbsp lactose-free milk or almond milk (max 1/2 cup total per serving), Optional: 1/4 cup dark chocolate chips (dairy-free). Check packaged ingredients carefully, especially broths, spice blends, gluten-free mixes, condiments, and dairy substitutes, because garlic powder, onion powder, inulin, chicory root fiber, high-fructose sweeteners, and wheat-based thickeners can appear in small print. When unsure, choose plain versions and add flavor with garlic-infused oil, fresh herbs, citrus, ginger, chives, scallion greens, or low FODMAP spice blends.

For IBS-friendly meal prep, cool leftovers quickly and refrigerate in shallow containers. Reheat only the portion you plan to eat, and add fresh herbs, lemon juice, or a small drizzle of garlic-infused oil after reheating to bring the flavor back without relying on high-FODMAP aromatics. If a recipe feels too rich during a flare, pair it with a simple low FODMAP side such as rice, potatoes, quinoa, lettuce, cucumber, carrots, or another tolerated vegetable.

This recipe is intended for general low FODMAP education, not medical advice. Individual tolerance varies, so use your dietitian’s guidance and your own symptom history when deciding whether to repeat, increase, or modify a serving. During the elimination phase, keep portions conservative; during reintroduction, test one FODMAP group at a time so you can clearly identify personal triggers.

Helpful next steps: use the FODMAP Food Checker before adding new ingredients, try the Ingredient Swap Tool when a sauce or seasoning is questionable, and save recipes that worked well so you can build a reliable rotation of breakfasts, lunches, dinners, and snacks.
