In a microwave-safe mug, add flour, cocoa powder, sugar, and a pinch of salt. Mix well to combine.
Add peanut butter, milk, and melted butter. Stir until the batter is smooth and slightly thick, like brownie batter.
Fold in chocolate chips for extra gooey texture.
Microwave on high for 1 minute. Check at 50 seconds if your microwave runs hot.
Let it cool for a minute to help the brownie set and stay fudgy.
Top with whipped cream, a drizzle of chocolate sauce, and a sprinkle of cinnamon powder.
For extra richness, swirl in a little more peanut butter before microwaving.
For added crunch, sprinkle chopped peanuts or crushed pretzels on top.
