Add your half cup of hot decaf coffee to a large mug. Add the butter and sweetener, if using, and stir to dissolve. Use a handheld stick blender or milk frother to carefully blend the coffee and fat.
Step 2
Add the almond milk to a small saucepan over low/medium heat. Heat through until piping hot, but don’t boil. Remove from the heat and carefully blitz with a frother or stick blender until the milk is fluffy and doubled in volume.
Step 3
Carefully pour the hot milk into your prepared butter coffee. The milk should sink towards the bottom whilst the froth remains on top. Serve hot.
