Tiramisu Overnight Oats With Real Espresso

• Real brewed espresso provides coffee flavor without extract or instant powder. Cool it before mixing to protect yogurt thickness, so oats set creamy rather than loose during their overnight rest.
• Dividing Greek yogurt between base and topping creates a creamy center with a pale layer. That contrast echoes tiramisu’s structure while keeping topping modest enough for make-ahead breakfast jars.
• Adding cocoa only at serving preserves its dry, slightly bitter finish and keeps the surface visually defined. The powder would absorb moisture overnight, darken, and lose the dessert-like contrast.

• 1/2 cup old-fashioned rolled oats (45 g)
• 1/4 cup cooled brewed espresso (60 g)
• 1/2 cup milk, dairy or unsweetened oat (120 g)
• 3/4 cup plain Greek yogurt, divided (180 g)
• 1 tablespoon chia seeds (12 g)
• 1 tablespoon maple syrup, divided (20 g)
• 1 teaspoon vanilla extract (4 g)
• 1 pinch fine salt (1 g)
• 2 tablespoons mascarpone cheese, softened (30 g)
• 1 teaspoon unsweetened cocoa powder (3 g)
• 1 tablespoon chopped dark chocolate, optional (10 g)

Ingredient notes

• Use old-fashioned rolled oats, not quick oats. Their larger flakes take on the espresso mixture overnight while retaining a little structure, which keeps the jar thick enough to eat with a spoon rather than drink through a straw.
• Brewed espresso is the main flavor here, so choose one you would happily drink. Two shots provide a clear coffee note after the milk and yogurt are added; cool them fully before measuring and combining.
• Plain Greek yogurt adds body and tang to both the base and topping. Full-fat or low-fat versions work; choose a thicker strained yogurt, since a loose regular yogurt can make the finished oats slack.
• Mascarpone makes the topping closest to tiramisu, but cream cheese works when softened first. Either option should be stirred with yogurt, maple syrup, and vanilla until no white streaks remain and the mixture spreads easily.
• Unsweetened cocoa powder supplies the final dessert-like bitterness. Sift it through a small fine sieve just before eating if possible, because cocoa clumps quickly on a moist surface and can taste harsh in concentrated spots.

1. 1Cool the espresso

   Pull or brew two espresso shots, then leave them uncovered until completely cool. You need 1/4 cup total. Hot coffee can loosen the yogurt mixture and leaves the jar warmer than necessary for an overnight rest. If espresso is unavailable, use 1/4 cup strongly brewed coffee, cooled, rather than adding extra liquid later.

2. 2Mix the oat base

   In a medium bowl, whisk the cooled espresso, milk, 1/2 cup Greek yogurt, maple syrup, vanilla, and a pinch of salt until smooth. Add the rolled oats and chia seeds. Stir slowly, scraping the bowl bottom, until every oat is coated and no chia seeds sit in a dry cluster.

   

3. 3Portion the jars

   Divide the oat mixture between two 12-ounce jars or lidded containers. Tap each container lightly on the counter to settle the mixture, then scrape down any oats clinging above the liquid line. Leave a little room at the top for the creamy layer, which is easier to add after chilling.

   

4. 4Stir the topping

   In a small bowl, mash the mascarpone with the remaining Greek yogurt, maple syrup, and vanilla. Stir until the topping looks smooth and soft, not stiff. Divide it over the oat mixture, spreading it gently to the edges. A thin even layer gives the cocoa a dry surface to sit on later.

5. 5Chill overnight

   Cover the jars and refrigerate for at least 6 hours, or overnight. The oats and chia need that quiet time to absorb the coffee-milk mixture. In the morning, check the texture with a spoon. If it seems unusually firm, fold in one tablespoon milk at a time only until creamy.

6. 6Finish with cocoa

   Right before eating, dust each jar with unsweetened cocoa powder. Add a few chopped dark chocolate pieces if wanted, keeping them on top so they stay distinct rather than disappearing into the oat base. Eat directly from the jar while cold, or transfer to a small bowl when a slower morning allows.

• Measure espresso after brewing and cooling, not before. Espresso volume varies slightly with crema, and the finished liquid amount matters more than the number of shots used to get there.
• Use jars with at least a 12-ounce capacity. The oats expand during chilling, and a cramped container makes the topping difficult to spread without smearing it into the base.
• Stir chia seeds into the liquid thoroughly before portioning. A second stir after two minutes is useful when they tend to settle, especially if the mixture has been standing while you prepare containers.
• Keep cocoa separate until serving. It will darken and absorb moisture on top of the yogurt layer overnight, losing the clean powdery finish that makes the jar resemble tiramisu.

Serve each jar cold with a spoon and a final cocoa dusting. A few dark chocolate shavings make the top feel more dessert-forward, while sliced strawberries offer a brighter contrast to the espresso. For a larger breakfast, pair the oats with a hard-cooked egg or a small piece of fruit. Keep the jar upright in a lunch bag if taking it along; the soft topping is best when it stays level rather than being shaken into the oats.
