Need to satisfy your sweet tooth on the fly? Your next sugar fix is only 6 minutes away with these devilishly easy low FODMAP mug cakes!

Low FODMAP mug cake in cup - 940 x 788

If you’ve spent any time in the dessert section of my website, you’ve probably noticed I have quite the sweet tooth! So believe me when I say it’s dangerous that I know how to make a cake in 5 minutes.

While there are a lot of mug cakes floating around online, this one is special! Most of the recipes I’ve seen use oil as their fat. But these mug cakes are no lowly muffin! So we’re using melted butter and cream (whaaat!). While melting butter adds an extra few seconds to your overall time, you’ll end up with a rich, decadent cake worthy of a true chocoholic!

If you want to go all in, this recipe is fantastic with a scoop of low FODMAP ice cream or a spoonful of freshly whipped cream. Sprinkles are optional but highly encouraged…

Heads up! This recipe is part of my 30 under 30 challenge! This month, I’ll be posting a new recipe every day that’s ready in 30 minutes or less! Hop on my mailing list if you haven’t already so you don’t miss anything!

Keep It FODMAP Friendly

Calling all my chocoholics! This low FODMAP mug cake can satisfy any sweet tooth in 6 minutes or less! Check out the notes below for tips on keeping this recipe FODMAP friendly!

First up is low FODMAP flour. If you’re in the elimination phase of the program, this means you’ll need to use a gluten-free flour blend. For my Canadian peeps, I’m a little obsessed with PC’s all-purpose gluten-free flour, and it’s perfect for projects like this one!

Remember, unless you have celiac disease, you’re avoiding the FODMAP fructan in wheat, not the gluten itself.

Next up, sugar. According to the Monash app, table sugar is low FODMAP in servings of 1/4 cup or 50 g per sitting. Though, they don’t list a maximum serving size. You can read more about these quirky foods here.

There’s a bit of confusion about sugar, as sugar is part glucose and part fructose. During the low FODMAP program, you’re trying to manage your intake of fructose in excess of glucose.

This means you’re trying to manage the number of fructose molecules floating around on their own. In table sugar, glucose and fructose appear in equal amounts and are absorbed through the glucose transporter – like a shuttle bus to the bloodstream-  even if the fructose transporter isn’t working correctly.

We’ll also be using cocoa powder. According to Monash University, cocoa powder is low FODMAP in servings of 2 heaping tsp or 8 g per sitting. Servings of 5 heaping tsp 20 g or more are high in the FODMAPs fructan and GOS.

Heads up, Monash has calculated their serving sizes so you can have more than one serving of each FODMAP group per sitting. Most FODMAP-trained dietitians recommend sticking to 1.5 servings of each FODMAP group per sitting to avoid FODMAP stacking.

Our recipe uses 3 heaping tsp or 12 g of cocoa powder. This works out to 1.5 servings of fructans and GOS per mug cake. This is within the recommended range.

This recipe also uses cream and butter. If you’re in the elimination phase of the program, you’ll need to use lactose-free cream. For my North American peeps, both Natrel and Lactantia both have lactose-free lines that go up to 35%.

You don’t need to worry about finding a lactose-free butter, though. According to the Monash app, butter is already low FODMAP (because it’s all fat). Just make sure to check the label for ingredients like milk and “milk solids,” and you’re good to go.

Last but not least is vanilla! According to Monash, vanilla extract is low FODMAP in servings of 1 tsp per sitting. Though, Monash doesn’t list a maximum serving size.

We’ll be using a dash of vanilla extract (1/8 tsp if your measuring spoons go that low). This works out to 2.5 g per serving which is well within Monash’s recommended range.
