Stir through the chopped Whitakers chocolate, keeping a few pieces aside for the top.

How to Store Your Homemade Chocolate Mug Cake
Eat this mug cake straight away for the best taste and texture. If some is left over, follow these steps to keep it fresh.
Let the cake cool down fully in the mug. Put a lid or cling film on top to stop it from drying out.
Place it in the fridge. It will stay good for up to 24 hours.
To eat later, warm it up in the microwave for 10 to 15 seconds. This brings back the soft, warm feel.
Do not freeze the mug cake, as it can change the texture and make it less enjoyable. Always make a fresh one when possible for that just-baked goodness with Whitakers dark chocolate chunks.
A Brief History of Mug Cakes
Mug cakes, those quick single-serve treats baked in a microwave, have roots stretching back thousands of years, evolving from simple ancient bakes to today's instant desserts.
The concept traces to ancient Egypt, where unleavened cakes were often savory and sometimes sweetened with honey, lacking any rise without leavening agents.
By the 18th century, bakers whipped eggs to create lift, though this was time-consuming and mostly for the wealthy.
Innovations like baking soda in the 1840s and baking powder in the 1860s made rising cakes accessible to more people through chemical leavening.
Cupcakes, a closer ancestor, appeared in the mid-19th century, often baked in coffee cups as small "test cakes" to check oven temperatures before thermostats existed.
The 1851 Great Exhibition in London showcased the first oven with a thermostat, standardizing baking and making it easier as sugar prices dropped.
The microwave oven, key to modern mug cakes, hit consumer markets in 1967.
However, the microwave mug cake as we know it—mixing basic ingredients like flour, sugar, and baking powder in a mug for quick cooking—gained traction in the early 2000s via internet cooking forums and mailing lists.
One of the earliest video tutorials popped up on YouTube in 2009, touting a recipe ready in under five minutes.
Popularity exploded around 2017-2018 with commercial mixes.
Duncan Hines released 18 flavors in 2017, Starbucks and Trader Joe's followed in 2018, and Betty Crocker set a world record for the largest mug cake mosaic.
Today, mug cakes represent solo eating trends, offering fast, customizable treats from basic pantries.
