A soft, gooey Lotus Biscoff Mug Cake bursting with warm speculoos spice, ready in under 5 minutes. Single-serve, microwave-friendly, egg-free, and totally irresistible—perfect for late-night cravings or a quick dessert fix.
- Total Time: PT7M
- Yield: 1 mug cake
Ingredients
4 tbsp (30 g) all-purpose flour
1 1/2 tbsp (18 g) light brown sugar
1/4 tsp baking powder
Pinch fine salt
3 tbsp (45 ml) milk (dairy or unsweetened oat)
1 tbsp (15 ml) neutral oil or melted butter
1/2 tsp vanilla extract
2 tbsp (32 g) Lotus Biscoff spread, divided
1 Lotus Biscoff cookie, crushed (plus extra for topping)
Optional: 1 tbsp mini chocolate chips
Optional: pinch ground cinnamon
Instructions
1. Use a microwave-safe 12–14 oz mug. Lightly grease the inside or spray with nonstick spray.
2. Add flour, brown sugar, baking powder, salt, and optional cinnamon to the mug. Whisk with a fork until well combined.
3. Stir in milk, oil (or melted butter), and vanilla until a smooth batter forms, scraping the bottom and sides.
4. Microwave 1 tbsp Biscoff spread for 10–15 seconds until runny. Swirl it into the batter. Fold in chocolate chips if using.
5. Microwave on High for 70–90 seconds. Start at 70 seconds; the top should look set but slightly glossy at the center.
6. Rest 1 minute to finish cooking gently. The crumb will set and stay moist.
7. Warm the remaining 1 tbsp Biscoff for 10–15 seconds and drizzle over the cake. Sprinkle crushed Lotus cookie on top.
8. Serve warm straight from the mug. Add ice cream or whipped cream if you like extra indulgence.
Notes
Microwaves vary—start at 70 seconds and add time in 5–10 second bursts.
For a lava center, undercook by ~5–10 seconds.
Make-ahead: jar the dry mix so dessert is 60 seconds away.

Lotus Biscoff Mug Cake Variations & Swaps
Dairy-free, gluten-free, and no-egg options
This Lotus Biscoff Mug Cake is naturally egg-free and easy to adapt for dietary needs. For dairy-free, use oat or almond milk and confirm your chocolate chips are dairy-free. For gluten-free, swap in a cup-for-cup all-purpose gluten-free blend; the cookie butter mug cake remains tender with a similar rise. Want lower sugar? Reduce the brown sugar to 1 tbsp—your Lotus Biscoff Mug Cake will still taste indulgent thanks to the Biscoff swirl. For a coffeehouse riff, add a teaspoon of espresso to the batter and you’ll have a mocha-speculoos vibe reminiscent of my Salted Caramel Chocolate Mug Cake—cozy, balanced, and bold.
Pinterest-favorite twists you’ll love

Or do a chocolate core: tuck in a square of dark chocolate for a lava-like microwave mug cake. For “birthday cookie butter,” add rainbow sprinkles. Craving fruit? Fold in diced strawberries or banana slices; the warm spice of speculoos spread plays beautifully with produce. A little sea salt on top makes the Lotus Biscoff Mug Cake pop.

Lotus Biscoff Mug Cake Storage, Fixes, and More
Storage and make-ahead tips
While the Lotus Biscoff Mug Cake is at its best fresh and warm, you can cover leftovers and keep them at room temperature for up to 6 hours or refrigerate for 1 day. Rewarm in 10–15 second bursts. For meal-prep comfort, whisk the dry mix (flour, sugar, baking powder, salt, cinnamon) and store it in a small jar. When the craving hits, stir in milk, oil, and vanilla, then swirl in Biscoff spread. You’ll have a ready-to-go microwave mug cake in seconds—perfect for late-night dessert emergencies.
Troubleshooting your mug cake
If your Lotus Biscoff Mug Cake turns gummy, it’s usually overcooked—shave off 10–15 seconds. If it’s dense, you might have overmixed; stir just until combined next time. A flat top often means outdated baking powder; replace it and your cookie butter mug cake will spring back to life. Dry cake? Add an extra teaspoon of oil or a splash more milk; the Lotus Biscoff Mug Cake will rebound with a tender crumb. Remember, microwaves vary, so your sweet spot might be anywhere from 70 to 95 seconds.
