For the coffee muffins, preheat the oven to 200 °C. Mix dry ingredients together. Whisk eggs and milk together.
Slowly add egg-milk mixture to dry ingredients and whisk well. Brew 2-3 tsp of instant coffee in a little hot water and fold into batter.
Divide batter among ramekins and bake for 20 minutes. A muffin baking pan is recommended as the batter is fairly runny.
Allow coffee muffins to cool and enjoy.
