Step 1 – Preparing the mug cake

Add the dry ingredients for the mug cake into a middle-sized bowl and mix them until well combined.

Step 2

  tbsp creamy sugar-free peanut butter, tbsp unsweetened almond milk, tbsp melted butter, egg, tsp vanilla extract

Add the remaining ingredients for the mug cake as well and mix them until you get a smooth and chunk-free dough.

Step 3

Grease your microwave-safe mug or ramekins with a small amount of cooking oil or fat.

Use something that doesn’t have a strong taste of it’s own, e.g. butter, avocado oil or coconut oil instead of something like olive oil.

Your mug should be at least double the size of the mixed ingredients.

Step 4

Add your mug cake batter into your mug or ramekins.

Step 5 – Microwave instructions

Microwave for about 1-3 minutes.
(The cooking time in your microwave may vary heavily depending on what settings you’re using.)

A broad rule of thumb: approx. 1 minute at 1200 watt and more like 2-3 minutes at <600 watt.

You can test if your mug cake is done with the “toothpick test”: prick the center of your mug cake with a toothpick – if it comes out clean and without any dough on it, it’s done!

Step 5 – Oven instructions

Preheat your oven to 350°F/180°C.

Bake your mug cake for about 10-15 minutes in your preheated oven.

Storage

Cover your low carb peanut butter mug cake with plastic wrap and store it in your fridge.

We recommend eating your mug cake on the same day or the day after, as it will dry out rather quickly.
