Vanilla Cupcakes

These low-FODMAP vanilla cupcakes swap wheat for a gluten-free 1:1 flour blend and use lactose-free milk, so the crumb stays soft without the fructans or lactose.

Ingredients

Cupcakes (makes 12)

• 1 3/4 cups (245g) gluten-free 1:1 flour blend, one without added inulin or chicory root
• 1/2 tsp xanthan gum (skip if your blend already lists it)
• 1 1/2 tsp gluten-free baking powder
• 1/4 tsp salt
• 1/2 cup (113g) unsalted butter, softened
• 3/4 cup (150g) white or superfine (caster) sugar
• 2 large eggs, at room temperature
• 2 tsp vanilla extract
• 3/4 cup (180ml) lactose-free milk, at room temperature

Vanilla buttercream

• 1/2 cup (113g) unsalted butter, softened
• 2 cups (240g) confectioners' (powdered) sugar, sifted
• 1 tsp vanilla extract
• 1 to 2 tbsp lactose-free milk
• Pinch of salt

Instructions

Make the batter

1. Heat the oven to 350F (175C) and line a 12-cup muffin pan with paper liners.
2. Whisk the flour blend, xanthan gum (if using), baking powder, and salt in a bowl and set aside.
3. Beat the softened butter and sugar with a mixer on medium until pale and fluffy, about 3 minutes. Add the eggs one at a time, beating well after each, then beat in the vanilla.
4. On low speed, add the flour mixture in three additions alternating with the lactose-free milk, starting and ending with the flour. Mix just until the batter is smooth and no dry streaks remain.

Bake

1. Divide the batter evenly among the 12 liners, filling each about two-thirds full.
2. Bake for 18 to 22 minutes, until the tops spring back when lightly pressed and a toothpick comes out clean.
3. Cool in the pan for 5 minutes, then move the cupcakes to a wire rack and cool completely before frosting.

Make the buttercream and frost

1. Beat the softened butter on medium until smooth, about 1 minute. Add the sifted confectioners' sugar in two additions on low speed, then beat in the vanilla and salt.
2. Add lactose-free milk 1 teaspoon at a time and beat on medium-high for 2 minutes, until light and spreadable.
3. Pipe or spread the buttercream onto the fully cooled cupcakes.

Tips & Substitutions

• Check your flour blend. Some gluten-free blends hide inulin or chicory root, which are high in fructans. Read the label and choose a plain rice-and-starch based blend.
• Xanthan gum keeps the crumb together. Gluten-free batters need a binder. If your blend already contains xanthan or guar gum, leave out the extra 1/2 teaspoon so the cupcakes don't turn gummy.
• Room-temperature ingredients matter. Cold eggs and milk can seize the butter and give you a dense crumb. Let them sit out for about 30 minutes before you start.
• Swap the milk. Any lactose-free dairy milk works. Unsweetened almond milk or macadamia milk are low-FODMAP alternatives if you also want dairy-free, though the buttercream still uses butter.
• Don't overfill the liners. Two-thirds full gives a rounded top with room to spread the frosting. Overfilled cups sink in the center as they cool.
• Adjust the frosting texture. Add more sifted sugar to stiffen it for piping, or a few more drops of milk to loosen it for spreading.

Why This Works

• Garlic and onion never appear. This is a plain vanilla bake, so there are no fructan sources from aromatics to work around.
• The flour blend replaces wheat. Wheat flour carries fructans, so a rice-and-starch gluten-free 1:1 blend gives you a low-FODMAP structure with the same measuring.
• Lactose-free milk cuts the lactose load. Regular milk is high in lactose. Lactose-free milk has the lactose already broken down, so the crumb stays tender without the FODMAP.
• Butter and sugar are low-FODMAP by nature. Butter is almost entirely fat with negligible lactose, and sucrose (table and confectioners' sugar) is a low-FODMAP sweetener, so the buttercream stays safe in a normal serving.

Storage

Store frosted cupcakes in an airtight container at room temperature for up to 2 days, or in the fridge for up to 5 days; bring chilled ones back to room temperature before serving so the buttercream softens. Unfrosted cupcakes freeze well for up to 2 months, wrapped individually; thaw at room temperature, then frost. Portions vary by person, so check the Monash app for current tested serving sizes if you are still in the elimination phase.
