Can I replace plain flour with wholemeal when making brownies?

You can definitely replace plain flour with wholemeal flour when making brownies, but be aware that it will change the texture and flavor of the brownies.

Here's what to expect and some tips:

Changes:

* Texture: Wholemeal flour will result in denser, chewier brownies, as the bran in the flour absorbs more moisture.

* Flavor: The brownies will have a slightly nuttier and earthier flavor, thanks to the whole grain.

* Color: The brownies will have a slightly darker, browner color.

Tips:

* Reduce the amount: Start by replacing up to half of the plain flour with wholemeal flour. You can adjust the ratio based on your preference.

* Add moisture: Wholemeal flour absorbs more moisture, so you may need to increase the amount of wet ingredients (like eggs or milk) by a tablespoon or two.

* Adjust baking time: The brownies might take a little longer to bake, so check for doneness with a toothpick.

Note:

* Don't use 100% wholemeal flour: It will result in a very dense and dry brownie.

* Consider using a blend: You can achieve a balanced flavor and texture by using a combination of plain and wholemeal flour.

Experiment and find the ratio you like best!
