Preheat the oven to 180C. Line a slice or cake tin.
Mix all ingredients in a bowl until combined.
Pour into the tin and bake for 25-30 minutes, or until it’s golden brown and a toothpick comes out clean.
Turn the oven off, leave the cake in for another 5 or so minutes with the lid ajar.
Remove from the oven and let it cool completely. Flip the cake so it’s upside down and peel off the baking paper.
Spread the whipped cream over the cake. Top with the strawberries and zest. Slice and enjoy.
