Why You‘ll Love This Recipe
- Simple ingredients: Everything you need is likely already in your kitchen.
- Quick to prepare: From start to finish, it takes only about 20 minutes.
- Deliciously indulgent: Perfectly buttery, sweet, and chocolatey.
Ingredients
- 50g unsalted butter
- 10g brown sugar
- 15g granulated sugar
- 70g cake flour (low-gluten)
- 3g baking powder
- 1 egg yolk
- 20g chocolate (choose dark, milk, or other types you prefer)
- 50g heat-resistant chocolate chips
Instructions
Soften the butter: Place 50g of unsalted butter at room temperature to soften. It should leave an impression when pressed lightly. If in a hurry, cut the butter into small pieces and microwave at low power for 10–15 seconds, being careful not to melt it excessively.
Mix sugars with butter: Add 10g of brown sugar and 15g of granulated sugar to the softened butter. Mix evenly with a spatula until fully combined.
Prepare dry ingredients: Sift together 70g of cake flour and 3g of baking powder. Add this mixture to the butter and sugar, folding gently with a spatula. Mix lightly from the bottom up until just combined, ensuring there’s no dry flour visible.
Add the egg yolk: Incorporate 1 egg yolk into the mixture and continue stirring with the spatula until the yolk is fully absorbed, making the batter smooth and consistent.
Mix in chocolate: Chop 20g of chocolate into small pieces and add it to the batter. Stir gently to distribute evenly. Preheat the oven to 180°C (356°F) at this stage if you haven’t already.
Fill molds and decorate: Transfer the batter into cupcake molds, filling each to about 70–80% full. Smooth the surface with a spatula, then sprinkle the 50g of heat-resistant chocolate chips on top for decoration and added texture.

Bake the mug cookie: Place the molds into the preheated oven and bake at 180°C (356°F) for 15 minutes. Keep an eye on the cookies, and when they turn golden brown, test with a toothpick inserted into the center. If it comes out clean, they’re done.
