Blondie for one, 138 calories and a minute in the microwave
August 17, 2026Updated September 16, 2026Total time: 6 minMakes: 1 serving
Some nights I want dessert but not a full pan of blondies staring at me from the counter for a week, so I make one in a ramekin and it's done before the microwave even finishes beeping.
The oat flour and PB2 keep it from tasting like a science experiment, it actually eats like a warm blondie. Start checking it at 45 seconds, a batch that runs even 15 seconds too long turns rubbery fast.

Tips & swaps
A small ramekin or oven-safe mug works best, a wide bowl spreads the batter too thin and it overcooks in seconds.
Start checking at 45 seconds. Microwaves vary a lot and a blondie that goes even 15 seconds too long turns rubbery.
PB2 keeps the peanut butter flavor without the fat of the real thing, but a scant teaspoon of real peanut butter stirred in at the end works too if that is what you have.
This does not keep well, it is built to be eaten right away while it is still warm.
