A nostalgic twist on a classic lunchbox favorite, these decadent sandwiches feature chewy peanut butter cookies filled with creamy, homemade raspberry ripple ice cream. They are the ultimate summer dessert for kids and adults alike.
Prepare the raspberry ripple: Place the frozen raspberries, lemon juice, icing sugar, and liquid glucose (if using) into a food processor. Blend until completely smooth, then press the purée through a fine-mesh sieve into a bowl to remove the seeds.
Make the ice cream base: In a separate large bowl, whisk the double cream, condensed milk, and vanilla bean paste together for about 5 minutes until the mixture is thick and holds its shape.
Ripple and freeze: Spoon the cream mixture into a freezer-proof container or a large loaf tin. Drizzle the raspberry purée over the top and use a skewer to gently swirl it through for a marbled effect. Cover and freeze overnight.
Preheat the oven: When ready to bake the cookies, preheat your oven to 180°C (160°C fan/gas mark 4). Line two large baking sheets with parchment paper.
Mix the cookie dough: In a medium bowl, combine the peanut butter, golden caster sugar, and light brown soft sugar with a large pinch of salt. Beat in the egg until the mixture forms a stiff dough.
Shape and bake: Roll the dough into 16 small balls (about the size of a cherry tomato) and place them on the prepared baking sheets, spaced well apart. Flatten each ball slightly with the back of a fork. Bake for 10–12 minutes until golden, then let them cool completely on the sheets.
Assemble: Once the cookies are cold, place a generous scoop of the raspberry ripple ice cream between two cookies to form a sandwich. Serve immediately. Note: You will likely have about 500ml of ice cream left over, which can be kept frozen for up to three months.
For the best texture, use a high-quality smooth peanut butter. If you prefer a bit of crunch, chunky peanut butter works well too. To ensure the sandwiches don't melt too quickly, you can pre-chill the cookies in the freezer for 15 minutes before assembling.
