Prepare the base by adding the digestive biscuits into a food processor and blitz for 5 seconds. Alternatively, you can add the biscuits into a ziplock bag and smash it with a rolling pin or spoon until fine crumbs form
Add the melted butter and milk and blitz for another 5-10 seconds until a slightly sticky crumble forms
Pour the base into a brownie pan lined with parchment paper, and using the back of a spoon or your hands, pat down until even. Place the base into the fridge while you prepare the cheesecake layer
Bloom the gelatine by adding milk into a small saucepan and sprinkling the gelatine on top, set aside for 5-10 minutes
Add the yogurt, light cream cheese and vanilla to a medium-sized bowl, and using an electric hand mixer or whisk, mix until well combined. (I prefer to use an electric hand mixer)
Pour the sweetener into the sauce-pan mixture, and over medium heat, mix until the gelatine and sweetener are fully dissolved. Let it cool slightly
Pour the gelatine mixture into the cheesecake batter and whisk until combined
Reserve 1/3 of the batter into another small bowl
Mash the raspberries until a puree forms, add the mixture into the reserved cheesecake batter and mix well. Make sure to reserve some raspberry puree for the top
Pour the cheesecake batter on top of the base, and spread evenly.
Pour the raspberry cheesecake batter on top and spread evenly
Add dollops of remaining mashed raspberries on top and swirl into the batter
Place the cheesecake to sit in the fridge for a minimum of 6 hours, but I usually leave mine for 24
When ready to serve, cut into 9-12 squares and enjoy
