Ingredients

Here’s everything you’ll need to make this cozy mug cake with simple, Low FODMAP pantry staples.

• Banana: Bananas can be tricky on a Low FODMAP diet since ripe bananas are higher in FODMAPs, but firm (just yellow) bananas are considered Low FODMAP in small portions. They add moisture and natural sweetness without added sugar.

• Gluten-free all-purpose flour: A 1:1 gluten-free flour blend keeps this cake soft and fluffy without the wheat. 

• Butter: A small amount of melted butter gives that rich, bakery-style flavor and helps the mug cake stay moist. If you’re sensitive to lactose, opt for a lactose-free or dairy-free butter alternative.

• Low FODMAP chocolate chips: Dark or semi-sweet chocolate chips (check that they’re dairy-free if needed) add just enough richness without causing digestion issues.

• Baking powder, vanilla, and a pinch of salt: These small but mighty ingredients help the mug cake rise, balance flavors, and create that irresistible banana bread aroma.

Mug Cake Variations

Switch things up with these easy flavor and texture ideas to keep your mug cake fun and fresh every time.

• Stir in chopped walnuts or pecans for a nutty bite that pairs perfectly with the banana flavor.

• Swap the butter for coconut oil or a plant-based spread to keep it rich and tender without lactose.

• Mix in a scoop of Low FODMAP protein powder to make this mug cake a more filling snack or post-workout treat.

• Add cinnamon, cocoa powder, or a touch of espresso for a deeper, cozier twist on classic banana bread.

Topping Ideas

The best part about mug cakes is how easy they are to dress up! Try one (or a few) of these simple topping ideas to make yours feel extra special:

• Add a dollop of lactose-free whipped cream for a light, creamy finish.

• Add a few thin slices of firm banana for natural sweetness and a pretty touch.

• Warm up peanut butter or almond butter for a rich, nutty drizzle over the top.

• Top with a scoop of lactose-free vanilla ice cream or a spoonful of Greek yogurt for a creamy, balanced finish.

Storage and Make-Ahead Tips

This mug cake is best enjoyed fresh, but here’s how to save it if you have leftovers or want to prep ahead.

• Storing: Leftovers (if you have any!) can be covered and refrigerated for a few hours, but the texture is always best when warm.

• Prep ahead: If you want to prep ahead, measure out the dry ingredients into a small jar and label it “Mug Cake Mix.” When you’re ready for dessert, mash the banana and mix in the wet ingredients!
