Pinch of Salt

It’s rich, soft, and slightly gooey in the center, with just the right balance of nutty peanut butter and sweetness. The best part? It takes just minutes to make in the microwave — no oven required.

Instructions

In a microwave-safe mug, add flour, sugar, baking powder, and salt. Mix with a fork.

Stir in the plant milk, peanut butter, vanilla (if using), and oil. Mix well until smooth with no lumps.

Microwave on high for 60–75 seconds, until the top is set and slightly springy. (Avoid overcooking—it will firm up as it cools.)

Let it sit for 1 minute. Enjoy warm straight from the mug!
