Peanut butter mug cake 3 ingredients is a quick and easy dessert made from egg, peanut butter, and sugar. I have experience making this mug cake, and I chose to prepare it after seeing a video online where it was made in just a few minutes.The main specialty of this peanut butter mug cake 3 ingredients is how fast it cooks while remaining soft, rich, and flavorful, offering a comforting treat without complicated steps.
Crack the egg into a microwave-safe mug. Add the peanut butter and sugar. Stir thoroughly with a fork or small whisk until smooth and well combined.
Check consistency:
The batter should be slightly thick but pourable. Scrape the sides of the mug to ensure all sugar and peanut butter is incorporated.
Microwave:
Microwave on high for 1 minute. Check the cake; if it needs more time, microwave in 15-second increments until set but still soft in the center.
Serve:
Let the mug cake cool for 1 minute before eating. Enjoy directly from the mug or transfer to a plate. Optional: top with a few extra peanut butter dollops or a drizzle of honey.
