Combine heavy cream, whole milk, and sugar in a large mixing bowl and whisk until sugar completely dissolves. Add vanilla extract, honey, and sea salt, stirring until the mixture becomes smooth and uniform throughout.
In a separate small bowl, whisk together cinnamon, nutmeg, and instant coffee with the egg yolks until pale and frothy. This spiced base will infuse your homemade ice cream with warm, complex flavors that make it unforgettable.
Slowly pour the cream mixture into the egg yolk mixture while whisking constantly to prevent scrambling. Temper the eggs gently by adding just a splash at first, then continue whisking and pouring until fully combined.
Stir in cocoa powder and maple syrup until completely incorporated with no lumps remaining. Let the custard base chill in the refrigerator for at least 2 hours or overnight for optimal flavor development.
While the base chills, prepare candied pecans by melting butter in a skillet over medium heat. Toast the chopped pecans with brown sugar for 3-4 minutes, stirring frequently until fragrant and caramelized.
Once the custard base is completely chilled, pour it into your ice cream maker and churn according to manufacturer instructions, typically 20-25 minutes. Transfer to a freezer-safe container and ripple in the candied pecans throughout.
Freeze the finished cozy ice cream dessert recipe for at least 4 hours until firm enough to scoop. For best texture and flavor, serve within one week.
