- Grease and line an 8 x 8 inch square pan. Place your crushed digestives into a medium sized bowl and pour the melted butter on top. Mix with a wooden spoon or spatula until all the digestive crumbs are coated with butter. 
- Tip the biscuit mix into the cake pan and push into all corners of the pan. Level off with a spatula or your hands, both work well. 
- Place the biscuit base in the fridge for at least 30 minutes. 
- Once the base is chilled, place the cream cheese and icing sugar into a large bowl or the bowl of your stand mixer. Beat until light and fluffy, about 2 minutes on med-high speed. 
- Add in the double cream and mix on a med-high speed until smooth and thick. 
- Add in the 6tbsp of lemon curd and mix until well combined. Pour over the biscuit base and smooth over until level. 
- Place a few dollops of lemon curd on top of the cheesecake and then, using a skewer, or similar, drag the lemon curd through the cheesecake making glorious swirls :) 
- Place in the fridge to set for at least 3 hours. 
- Once chilled and set, slice into 9 or 12 bars depending on how big you want them. 
- Bars will keep in an airtight container in the fridge for 3 days.
