Combine whipping cream, honey, sugar, and blueberry jam in a medium saucepan. Heat just until sugar dissolves, whisking frequently. Transfer to a glass bowl. Refrigerate until cold, about 2 hours.
To cream mixture, add buttermilk, lemon zest and juice, vanilla, and blackberry brandy. Whisk until well-combined.
Follow ice cream maker instructions for making ice cream. Mine takes about 20 minutes to churn.
Once ice cream is almost finished churning, heat blueberry jam just enough to make it easier to work with.
Add ⅓ of ice cream to a loaf pan or other dish, drizzle ⅓ of blueberry jam over the ice cream and swirl it in with a table knife. Top with ½ of frozen blueberries and ⅓ of crushed cookies. Repeat twice but only top with jam and cookie crumbs on the final layer. You will have 3 layers of ice cream total. Cover and freeze until solid, about 4 hours. Serve and enjoy!
