Brew the coffee: Prepare a strong coffee — one or two espresso shots or 120 ml cold-brew concentrate. If using hot espresso and you plan to chill, let it cool to room temperature (or use slightly warm if dissolving honey/maple first).
Combine liquids: In a mixing bowl or a 16–20 oz mason jar, pour 1 cup milk and 1/2 cup strong coffee. Add the vanilla extract and a pinch of salt. Stir to combine.
Sweeten: Stir in 1 tablespoon of maple syrup (taste and add a second tablespoon if you prefer sweeter). If using honey or thick syrup, dissolve into the warm coffee before adding cold milk.
Add creaminess (optional): Whisk in 2 tablespoons Greek yogurt or 1–2 tablespoons coconut cream for an extra-silky texture.
Add chia seeds: Sprinkle 3 tablespoons chia seeds into the liquid while whisking briskly to distribute seeds evenly and prevent clumps. If using a jar, cap and shake vigorously for 20–30 seconds.
Rest and re-stir: Let the mixture sit 5–10 minutes, then whisk or shake again to break up any initial clumping and ensure even hydration.
Chill: Cover and refrigerate for at least 2 hours, ideally overnight (6–12 hours). Chia seeds will swell and create a custard-like texture.
Finish and adjust: Before serving, stir the pudding well. If too thick, fold in a splash of milk until you reach the desired consistency. Taste and add a touch more sweetener or coffee if needed.
Serve: Portion into bowls or jars. Add toppings such as shaved chocolate, toasted nuts, fresh berries, sliced banana, or a swirl of whipped cream/coconut cream. Enjoy chilled.
