Notes
Best and Easiest Chocolate Brownies Recipe Tips
Use the best chocolate you can find - I use some milk chocolate combined with a bae that is 60 - 75 %.
It’s better to undercook them slightly then to bake them too much - overcooked brownies are dry so it is better to take them out at the 25 minute mark and then leave them to set. Remember, they will continue to bake in the hot pan once they are out of the oven. Then gently lift them out of the tray and onto a cooling rack.
Wait for them to cool - As tempting as it is, to face plant the entire tray, it is better to let them cool so they develop a better structure. I generally keep them in the fridge overnight and watch my kids roll their eyes at me for some of those hours.
Fold in the flour gently - You don't want to create air pockets or make the brownies too tough so be gentle.
Lighter coloured pans are better to bake brownies in - Darker tins bake cakes quicker so adjust timings if needed.
If your tin size is different, you will need to adjust baking times - 17 cm x 27 cm (40 - 43 minutes), 20 x 30 cm (23 minutes), 23 cm x 33 cm (18 minutes).
Storage
These brownies keep well for up to a week in an airtight container in the fridge or a cool place.
Freezer
They also freeze well for up to 3 months if wrapped well in 2 layers of cling film, then 2 layers of foil. To thaw, leave at room temperature for 3 - 4 hours.
Variations for Easy Chocolate Brownies Recipe
Add chopped nuts like Peanuts, Walnuts, Pecans.
Fold in some treats like Biscoff Biscuits, M & Ms, Oreos, Marshmallows. If adding on top, add them towards the end of baking time.
If you want to add Caramels - add them 2 - 3 minutes towards the end of cooking time.
