Instructions

Begin the low carb mug cake recipe by gathering all the necessary ingredients – the full list is in the recipe card below.

First, grab a microwave-safe mug or a small bowl to prepare your cake. Mix the dry ingredients, which include coconut flour, Swerve, Himalayan salt, and baking powder.

Next, add the wet ingredients to the mix, including a medium-sized egg that is at room temperature. 

Crack the egg into the mug, ensuring there are no shell fragments. With the egg, add the vanilla extract. 

Then, add the melted coconut oil.

Lastly, mix in the creamy peanut butter. Be sure to mix well until everything is combined into a smooth batter. Ensure there are no lumps and everything is uniformly combined. 

Optional: In addition of peanut butter, you can add sugar-free chocolate chips or pieces of dark chocolate if you prefer a chocolate peanut butter mug cake.

Once the peanut butter mixture is ready, microwave it. The appropriate time would range from 60-90 seconds, depending on your microwave’s wattage.

Step back and watch your mug cake bake quickly and efficiently in the microwave.

Monitor your coconut flour mug cake’s progress by watching it rise in the microwave. If it starts to spill over, stop the microwave, let the cake settle, and then continue cooking.

Once done, let it cool for a few minutes. Enjoy your delicious, quick, and easy keto peanut butter mug cake!

Choosing the Right Mug

When it comes to making a mug cake, the size of your best mug cake mug matters. A standard-sized coffee mug, roughly 8 to 12 ounces, is the best bet for ensuring your cake rises properly and cooks evenly. It also provides enough space for the ingredients to mix together properly.

This is the mug I use!

Order of Mixing Ingredients

The order in which you mix your ingredients can impact the texture of your cake. Start by combining your dry ingredients. Mix these in your chosen mug until they’re well incorporated.

Next, add your wet ingredients. Stir in each one at a time, making sure the previous ingredient is well mixed before adding the next.

Storing Keto Peanut Butter Mug Cake

Immediate Consumption: The mug cake is best enjoyed immediately after it’s prepared, for the freshest taste and texture.

Short-Term Storage: If you have leftover mug cake, you can store it in an airtight container or wrap it with plastic wrap. Keep it at room temperature for up to one day. However, be aware that the texture might change slightly when reheated.

Refrigeration: For longer storage, place the mug cake in the refrigerator. Wrap it in plastic wrap or store it in an airtight container to prevent it from drying out. It can be stored in the fridge for up to three to four days.

Reheating: To enjoy the leftover mug cake, reheat it in the microwave for about 10-15 seconds. Be cautious not to overheat, as it can become rubbery or dry.

Freezing (Recommended): For even longer storage, freeze the mug cake. Wrap it tightly with plastic wrap, place it in a resealable plastic bag, and store it in the freezer. It can be frozen for up to two to three months. When you’re ready to enjoy it, thaw it in the fridge overnight, then reheat in the microwave as needed.

This keto peanut butter mug cake is quick, easy, and perfectly portioned. For the best results, choose the right mug size and follow the steps in order. 

Cooking time varies, so adjust for your microwave’s power. These tips will help you make a tasty mug cake. Whether you’re a keto beginner or a pro, remember: be true, learn, and apply your knowledge. Enjoy making and eating keto desserts. That’s a wrap on our keto mug cake journey!
