Make the chia pudding: Mix together the chia seeds, milk, honey, and vanilla. Refrigerate for at least 2 hours until it thickens.
Make the cream: Stir the yogurt or mascarpone until smooth with the honey and vanilla.
Make the coffee: Brew a shot of espresso, then let it cool slightly.
Layer: In a glass or dessert jar, layer as follows: chia pudding, coffee, cream. Repeat the layers once more.
Finish: Dust the top with cocoa powder, then refrigerate for 30–60 minutes so the flavors can meld together.
For an extra dessert experience, you can also add finely chopped dark chocolate, ground almonds, or a little Matcha powder.
