A little indulgence goes a long way, and so do these Double Chocolate Muffins! Each of these muffins come with a generous filling of chocolate chips and chopped walnut with a dark chocolate base muffin. If you’re a chocolate lover like me, you will be sure to fall in love with these.

The best news I can share here will be how easy and fuss-free it is to make these Double Chocolate Muffins.

Firstly, as per my usual recipes, this is a one-bowl recipe which requires straightforward and easy-to-find ingredients. Additionally, you can easily customise the recipe according to your preferences. For example, you can swap out more chocolate chips for more nuts.

Next, you will also realise that each step requires beginner-friendly techniques including simple mixing, whisking, and folding. However, do take caution not to overfold the batter as it can create a denser finish!

Finally, you can also refer to the prepared video guide to gauge the consistency of the batter and each step. Otherwise, you can also feel free to reach out to me should you have any questions.

Without further ado, the recipe!
