Grease a 19x30 cm lamington pan or a 20cm round cake pan. Line base and sides with baking paper, extending paper 3cm above edges of pan.
Place the dates, boiling water and bi-carb soda in a bowl and set aside for 5 mins to soften.
Meanwhile, add the butter and brown sugar into a food processor.
Beat in eggs, one at a time, until combined.
When soft, add the dates and blend for 15 seconds until the mixture is smooth and combined.
Scrape down the sides, then add the flour.
Blend until all combined. You may need to scrape down the sides again.
Pour into prepared pan. Cook in a moderate oven 180C for 25 mins, or until cooked when tested. Stand in pan for 5 mins before turning out onto a wire rack to cool.

Combine the cream and jersey caramels in a medium saucepan.
Stir over a medium to low heat until caramels are dissolved and mix is smooth.
Pour into a medium bowl. Cover the surface with cling wrap. Refrigerate until cold.
Beat with an electric mixer until light and fluffy. Spread frosting over top of cold cake. Cut into squares to serve.
