RECIPE NOTES & TIPS
Line your tin with baking paper/parchment paper. This will make it easier to remove them from the tin later. Leave the edges over hanging slightly for convenience.
Sift the plain flour before adding it to the batter.
Don’t overmix the batter once the flour has been added. Overbeating will add air, which will produce cakey brownies, rather than fudgy.
Don’t overbake! Brownies will continue to cook after they’ve been removed from the oven. So, it’s best to remove them when they are slightly under cooked, rather than over cooked. All ovens differ slightly, so start to check them at the 20-minute mark and then in 5-minute intervals until they are ready.
For fudgy/moist brownies, cook for 35 minutes and test with a toothpick which should come out with less thick mixture on it. The top should be flaky and set. Remove them from the oven when the sides have begun to shrink away from the tin but the centre is still gooey.
For gooey brownies, cook for 30 minutes and test by inserting a toothpick into the centre for a second or two. If the toothpick is covered in thick (but not runny) chocolate mixture, then you will have gooey brownies.
Cool before cutting - allow espresso brownies to cool in the tin before cutting into them. You will have neater slices if they are cut at room temperature.
Serve the brownies - on their own, dusted with icing sugar or slather ganache or frosting over the top. You can also heat them and add a dollop of cream, or a big scoop of your favourite ice cream!
Storage - store espresso brownies in an airtight container at room temperature for up to 4 days or freeze for up to 3 months.
