In a bowl, combine the yogurt and cooled espresso. Mix well until smooth.

Add the honey and stir until fully incorporated and creamy.

Lightly dip the Speculoos cookies into the yogurt mixture and layer them in a serving dish or bowl.

Spread a layer of yogurt mixture over the cookies.

Repeat the layers until all ingredients are used, finishing with a layer of yogurt.

Cover with cling film and refrigerate for at least 3 hours, or until set.

Just before serving, dust generously with cocoa powder.
