Notes

RECIPE NOTES & TIPS:

For fudgy/moist brownies, cook for 25-30 minutes and test with a toothpick which should come out with moist (but not wet) crumbs on it. The top should be flaky and set.
For best results use store-bought smooth and creamy peanut butter.
For extra peanut butter flavour, add some Reese's Pieces or mini peanut butter cups to the batter.
For an extra indulgent treat, serve the brownies warm with a scoop of vanilla ice cream.
Storage - store brownies in an airtight container at room temperature for up to 4 days or in the fridge for up to 5 days.
Freezing - freeze in an airtight container in the freezer for up to 3 months. To thaw, leave the slices in a container in the fridge overnight, or sit them at room temperature for 1-2 hours.
