Add the erythritol to a food processor and blend on a high-speed setting until powdered. Set aside.
Step 2
Heat the almond milk in a small pan and add the coffee. Stir until dissolved then set aside to cool completely.
Step 3
Add the powdered erythritol, cold coffee mixture, almond extract, and cream to the bowl of a stand mixer. Using a whisk attachment, whisk the ingredients together at a high speed until the cream begins to thicken- this may take a couple of minutes. Once it starts to thicken, reduce the speed and continue to whisk until thick and fluffy peaks form on the surface. Divide the mixture evenly between 4 serving glasses or ramekins.
Step 4
Roughly chop the almonds and scatter them over the syllabub to serve.
