Baking parchment or baking paper
Square cake tin
1 Upturn your tin and measure the base of the tin to get an accurate measurement.
2 Take a large sheet of baking parchment or non-stick baking paper big enough to cover the base and sides of the tin.
3 Cut to size. Make large diagonal cuts in each corner of the paper.
4 Ease the paper into the tin, pressing well into the corners.
5 Trim off excess paper around the top if it extends more than 1cm.
6 Now you’re ready to spoon in your cake mixture.
Fix a flop
Avoid old fashioned greaseproof paper, because it can stick to the cake mixture!
