The Hero We Didn’t Know We Had

Ever heard of Jan Boone Senior? Nor had I. But the story of Biscoff begins in 1932 in Belgium when a baker named Jan Boone Sr. decided to create a new cookie to accompany coffee. He called it “Speculoos,” and it quickly became a beloved treat throughout Europe.

In the 1950s, a new production technique made it possible to turn the crunchy cookie into a spreadable butter. This was the birth of Biscoff Spread, the key ingredient in this Biscoff Mug Cake.

The popularity of Biscoff Spread grew rapidly, and in the 1980s, the company that produced it, Lotus Bakeries, began exporting it to other countries. It wasn’t until the early 2000s, however, that Biscoff Spread truly exploded in popularity thanks to the power of the internet and social media.

A Homage to Jan Boone Sr… My Biscoff Mug Cake

The beauty of this Biscoff Mug Cake recipe lies in its simplicity. All you need is a microwave-safe mug, some flour, sugar, baking powder, plant-based milk, and of course, the delicious Biscoff spread. You simply mix the ingredients together, pop the mug in the microwave, and within minutes you’ll have a warm and delicious cake!

So, let’s stop messing around. Go and grab your mug, your flour, your baking powder etc etc., and let’s get cracking (but strictly no eggs…)

The Biscoff Mug Cake Ingredients

If you’re going to make this delicious Biscoff Mug Cake, you’re going to need…

Plain Flour: The main purpose of flour in this recipe is to provide structure and texture to the cake. The protein in the flour, when mixed with liquid, forms gluten which gives the cake its structure. Plain flour, also known as all-purpose flour, is a versatile type of flour that is suitable for most baking recipes, including this one.

Biscoff Spread: Biscoff spread, also known as cookie butter, is made from ground Biscoff cookies. It has a sweet, slightly spiced flavour that adds a unique taste to the cake. It also helps to keep the cake moist due to its high fat content.

Neutral Oil: Neutral oil, such as vegetable or canola oil, is used to add moisture to the cake and keep it soft and tender. It also helps to prevent the cake from sticking to the mug.

Dairy-Free Milk: Dairy-free milk, such as almond or soy milk, is used to provide moisture to the cake and to help the ingredients bind together. It is also suitable for people who are lactose intolerant or following a vegan diet.

Sugar: Sugar adds sweetness to the cake and helps to balance out the flavours of the other ingredients. It also helps to give the cake a golden brown colour when baked.

Baking Powder: Baking powder is a leavening agent that helps the cake to rise and become fluffy. It works by releasing carbon dioxide gas when it comes into contact with liquid and heat.

Cinnamon: Cinnamon adds a warm, sweet, and slightly spicy flavour to the cake. It also has anti-inflammatory and antioxidant properties, which makes it a healthy addition to the recipe.

Pinch of Salt: Salt enhances the flavours of the other ingredients and helps to balance out the sweetness of the cake.

Biscoff Biscuit: The Biscoff biscuit is used to crumble on top of the cake for added texture and flavour. It also adds to the overall presentation of the cake.

Vegan Cream: Vegan cream, made from plant-based ingredients, is used to add a creamy texture and flavour to the cake. It is also suitable for people who are lactose intolerant or following a vegan diet.

Biscoff Mug Cake Making Tips

Be Careful Not to Over-mix the Ingredients

Over-mixing can cause the gluten in the flour to develop too much, resulting in a tough and dense cake. Mix until just combined for a fluffy and moist texture.

Keep an Eye on the Biscoff Mug Cake While it’s Cooking in the Microwave

Microwaves can vary in power, so it’s important to check the cake regularly to prevent overcooking. After 60 seconds, check the cake’s progress, and then check every 30 seconds after that until it’s cooked to your liking. Be careful not to overcook it, as this can result in a dry cake.

Make Sure the Mug You Use is Microwave Safe and Does Not Have Any Metallic Paint or Parts

Metal can cause the mug to heat up too quickly, potentially causing a fire hazard. Check the mug’s label to ensure it’s microwave safe. Alternatively, use a ceramic or glass mug, which are generally safe for microwave use.

If you Don’t Have a Microwave, You Can Still Make This Cake!

Simply bake it in a preheated oven at 180°C for around 8 minutes or until it’s cooked through. Keep an eye on the cake and check it regularly to prevent overbaking.

Customise Your Biscoff Mug Cake

Customising your Biscoff Mug Cake is a great way to make it your own and experiment with different flavours and textures. Here are some ideas to inspire you:

Toppings: Add some extra sweetness and texture to your Biscoff Mug Cake by topping it with vegan whipped cream, vegan chocolate chips, sprinkles, or crushed Biscoff cookies.

Mix-ins: Fold in some additional ingredients to give your Biscoff Mug Cake a unique twist. Some great options include chopped nuts, dried fruit, or even a spoonful of a Vegan Nutella alternative.
