Place the butter and cream cheese in your chosen mug. Microwave on HIGH for 20 seconds.
Add the coconut flour, sweetener, vanilla, and baking powder. Mix well. Add the egg. Mix again
Scrape down the sides of the mug, then press in 6 frozen raspberries into the cake batter.
Microwave on HIGH for 1:20 seconds minute.
You can reduce the total carbs further by omitting the raspberries (1.5 total carbs) to make a simple keto vanilla mug cake. Please adjust the microwave cooking times according to the strength of your microwave.My microwave is pretty powerful and only requires 1 minute, but most standard microwaves may require the 1:20 as stated in the recipe.No microwave? No problem. Simply bake at 180C/350F in a cupcake case or muffin tray for 12 minutes.
