Grin Affair

About Grin Affair

Grin Affair is a Bishan-based dessert maker specialising in individual moussecakes, seasonal dessert bundles, and handcrafted gelato pints, sold for islandwide delivery and pickup in Singapore.

The brand's approach is built around using natural, real ingredients — the kind you'd already have in your own kitchen — and leaving out artificial flavourings, preservatives, and thickeners. Their moussecakes and gelato are made with less sugar so they don't taste sickly sweet, and less oil so they sit lighter than a typical rich dessert.

The core range is a rotating line-up of individual moussecakes in flavours from Banana Dark Chocolate and Hazelnut & Praline through to Durian D24, alongside seasonal specials like Matcha & Coffee and Honey Lavender & Blueberry, plus Christmas bundle sets. Alongside the cakes, Grin Affair also makes a small handcrafted gelato pint range in flavours such as Earl Grey, Matcha, Durian D24, and Valrhona Dark Chocolate.

Orders are taken online and delivered daily across Singapore, with a same-day, multiple-timeslot delivery service and a free-delivery threshold for larger orders.

Grin Affair: Bishan's Natural-Ingredient Moussecakes and Gelato

Tucked into a Bishan Street 11 unit, Grin Affair makes its name on individual moussecakes and handcrafted gelato pints built around one simple rule: use the kind of real, natural ingredients you'd already find in your own kitchen.

What they're known for

Grin Affair's core belief is that dessert should be part of everyday life — but only if it's made from real food, without artificial flavourings, preservatives or thickeners. That shows up in how their moussecakes and gelato are made: less sugar, so nothing tastes sickly sweet, and less oil, so the desserts sit lighter than a typical rich cake.

The result is a rotating range of individually portioned moussecakes and gelato pints designed to be ordered online and delivered, rather than a sit-down cafe experience.

Signature moussecakes

The signature line-up spans familiar and adventurous flavours — Banana Dark Chocolate, Dark Chocolate, Banoffee, Cookies & Cream, Mango Custard, Vanilla & Strawberry, and Salted Caramel & Almond Nibs sit alongside premium options like Hazelnut & Praline, Lychee Passionfruit & Roasted Pistachio, and a Durian D24 moussecake for those who want a distinctly Southeast Asian flavour in cake form.

Seasonal specials and bundles

Alongside the standing range, Grin Affair runs seasonal specials — Matcha & Coffee and Honey Lavender & Blueberry have both featured — plus limited flavours like Spiced Dark Chocolate and Matcha & Azuki, which can sell out. For bigger occasions, they also offer bundle sets: a Christmas Set for 8 with free islandwide delivery, and a smaller Mini Christmas Set for 4 that's been one of their best sellers.

Handcrafted gelato pints

Beyond the moussecakes, Grin Affair makes a small range of handcrafted 473ml gelato pints. Flavours include Earl Grey, Vanilla & Black Cookies, Peppermint & Black Cookies, Matcha, Durian D24, Honey Jackfruit, Roasted Coffee, Butterscotch, and Valrhona Dark Chocolate — giving the same natural-ingredient approach in a scoopable format.

Ordering and delivery

Grin Affair operates as a delivery-and-pickup dessert business from its Bishan address, taking orders online. Delivery runs daily across Singapore in three timeslots — 9am to 12pm, 12pm to 4pm, and 4pm to 8pm — with same-day delivery available to multiple locations. Delivery is charged at $8 per trip for orders above $35, $14 per trip for orders below $35, and becomes free for orders above $70.

The experience

What sets Grin Affair apart is the combination of indulgent-sounding flavours — durian, lychee passionfruit, hazelnut praline — with an ingredient philosophy built around restraint: less sugar, less oil, nothing artificial. It's dessert positioned as something you can have often, not just as an occasional treat, delivered straight to your door in individual portions or as part of a shareable bundle.
