Combine all ice cream ingredients except heavy cream in a medium bowl, whisking to dissolve sugar and espresso.
Add heavy cream and stir to combine.
Cover and refrigerate for 4+ hours.
While Ice cream is chilling, chop and toast almonds then set aside to cool.
Just before churning ice cream, make ganache by heating heavy cream in a small saucepan until just barely steaming. Remove from heat, add chocolate, and stir until smooth, then set aside to cool.
Churn in ice cream maker for 20 minutes or until thick and smooth.
In a large plastic container, layer ⅓ ice cream, drizzle with ⅓ ganache, and sprinkle with ⅓ almonds. Repeat to use all ingredients, then cover and freeze several hours to firm.
