Why This Recipe Works
This Peanut Butter Mug Cake works because the peanut butter adds richness, moisture, and flavor without requiring complicated ingredients.

Additionally, cooking the batter in a mug helps the cake rise evenly while staying soft and tender.
Because everything cooks so quickly, you get fresh homemade dessert in just minutes.
Expert Tips for the Best Peanut Butter Mug Cake
Use creamy peanut butter for the smoothest texture.
Measure the flour carefully to prevent a dry cake.
