# Vietnamese Coffee Cookies > Crisp, espresso-kissed chocolate sandwich cookies filled with a sweet, coffee-forward buttercream made with sweetened condensed milk — a trendy Vietnamese coffee twist on the classic sandwich cookie. They photograph beautifully as uniform cookie rounds and deliver an intense, slightly caramel sweet coffee flavor that performs well on social media and at coffee-themed gatherings.

I use instant Vietnamese-style coffee—intensely aromatic and slightly chocolatey—to bloom a concentrate that is folded into the dough and again, sparingly, into the buttercream; the result is a focused, coffee-first profile rather than a polite background accent. Rolling and chilling the dough into precise logs produces uniformly round biscuits that bake evenly and photograph beautifully, which matters when the presentation is part of the appeal. This version prioritizes balance: a restrained amount of powdered sugar in the cookie keeps bitterness alive against the unabashed sweetness of the filling, while the condensed milk gives toasted-sugar complexity without thinning the buttercream. Make these for coffee-themed gatherings, gift boxes, or a weekend bake when you want something a touch fancier than a brownie but easier than layered patisserie; they travel well and hold their shape, so you can stack them in tins or arrange them on a slate platter for a striking display. ## Recipe Information - Prep Time: 45 minutes - Cook Time: 12 minutes - Total Time: 57 minutes - Servings: 7 - Difficulty: Medium - Category: Desserts ## Ingredients ### Bloom the coffee - 2 tbsp Instant Vietnamese-style coffee (or instant espresso powder) - 2 tbsp Hot water (to bloom the coffee) ### Cream butter and combine dry ingredients - 1 cup Unsalted butter (softened; total for dough + filling) - 1 1/2 cups Powdered (confectioners') sugar (total for dough + filling) - 1 large Large egg yolk - 1 tsp Vanilla extract - 1 3/4 cups All-purpose flour - 1/3 cup Unsweetened cocoa powder - 1/4 tsp Fine sea salt ### Make the condensed-milk coffee filling and assemble - 1/2 cup Sweetened condensed milk (for filling) ## Ingredient Guide ### Instant Vietnamese-style coffee (or instant espresso powder) Instant Vietnamese-style coffee typically refers to a dark-roasted, robusta-based instant coffee (sometimes blended with chicory) used for strong, bittersweet Vietnamese-style brews like cà phê sữa đá. It tastes very bold, roasty and slightly bitter compared with milder arabica instant coffees and has an intense coffee aroma. Find it at Asian groceries or online (brands like Trung Nguyen, Vinacafe, Vinacafé or other Vietnamese/SE Asian brands); a good substitute is instant espresso powder or any dark-roast instant coffee. ### Sweetened condensed milk (for filling) Sweetened condensed milk is cow’s milk cooked down and preserved with a high amount of sugar until thick and syrupy; it’s a staple in many desserts and in Vietnamese iced coffee. It’s very sweet, milky and caramel-like in aroma and adds creaminess and sweetness rather than pure dairy richness. You can find it canned in the baking/canned milk aisle of most supermarkets or Asian markets; a quick substitute is to simmer whole milk with sugar until reduced (or stir granulated sugar into evaporated milk, though the texture and flavor won’t be exactly the same). ## Instructions ### 1. Bloom the coffee Stir the instant Vietnamese-style coffee into the hot water until fully dissolved and aromatic. Set the coffee concentrate aside to cool while you prepare the rest of the ingredients; reserve a tablespoon for the filling if you'd like an extra coffee hit. ### 2. Cream butter and combine dry ingredients In a large bowl, beat the softened butter and 1 cup of the powdered sugar until light and fluffy (about 2–3 minutes). Mix in the egg yolk, vanilla and 1 to 2 tablespoons of the cooled coffee concentrate, then fold in the sifted flour, cocoa powder and salt until the dough just comes together—avoid overworking. ### 3. Shape the dough and chill Turn the dough out onto parchment and shape into two uniform logs about 1 to 1¼ inches (2.5–3 cm) in diameter; wrap tightly in plastic. Refrigerate at least 30 minutes (or up to 24 hours) so the logs firm up for clean slicing—this step gives consistently round cookies that look great in photos. ### 4. Slice and bake the cookies Preheat the oven to 350°F (175°C). Slice the chilled logs into 1/4-inch (6 mm) rounds, arrange on a parchment-lined baking sheet 1 inch apart, and bake 10–12 minutes until edges are set but centers remain slightly soft. Let the cookies cool completely on the pan for 5 minutes, then transfer to a wire rack to cool fully. ### 5. Make the condensed-milk coffee filling and assemble In a bowl, beat the remaining softened butter with the remaining powdered sugar until smooth, then add the sweetened condensed milk and 1 teaspoon of the reserved coffee concentrate (more to taste) and beat to a spreadable consistency. Pipe or spread a heaping teaspoon of filling onto the flat side of one cookie and sandwich with a matching cookie; dust lightly with a pinch of cocoa or a few grounds of instant coffee for garnish. ## Nutrition Estimated nutrition per serving (2 cookies (70g)): - Calories: 316 kcal - Protein: 3.4 g - Carbohydrates: 32.6 g - Fat: 19.9 g - Saturated Fat: 11.5 g - Trans Fat: 0 g - Fiber: 1.1 g - Sugar: 15.1 g - Added Sugars: 14.5 g - Cholesterol: 56 mg - Sodium: 56 mg - Potassium: 126 mg - Calcium: 26 mg - Iron: 1.5 mg - Vitamin D: 0 mcg ## Tips ### Bloom the Coffee Use very hot water and stir until completely dissolved and fragrant; let the concentrate cool before adding to butter so it won’t melt the butter and ruin dough texture. ### Butter Softness Test Butter should yield when pressed but still hold shape—too soft causes spreading and too cold makes creaming uneven, so temper it on the counter for 30–45 minutes depending on room temperature. ### Chill Logs for Clean Slices Refrigerate the formed logs at least 30 minutes (longer in warm kitchens) so you can slice thin, perfectly round cookies; if slices soften while you work, return the tray to the fridge for a few minutes. ### Slice with Precision Use a sharp chef’s knife, bench scraper, or unwaxed dental floss to cut the chilled logs in a steady sawing motion, wiping the blade between cuts for neat edges. ### Adjust Filling Texture If the condensed-milk buttercream is too loose, chill it briefly or add a little more powdered sugar; add the reserved coffee concentrate teaspoon by teaspoon to avoid overpowering the sweetness. ## Variations and Substitutions ### Dairy-Free/ Vegan Swap Use a high-quality vegan stick butter and coconut condensed milk (or make reduced coconut milk) for the filling; expect a slightly coconutty note and chill a bit longer to firm the buttercream. ### Gluten-Free Cocoa Cookies Substitute a cup-for-cup gluten-free all-purpose flour blend and chill the dough a bit longer to stabilize; the texture will be slightly more fragile but still crisp and sandwichable. ### Dark Chocolate Ganache Filling Replace the condensed-milk buttercream with a coffee-infused ganache (equal parts chopped dark chocolate and hot cream plus a teaspoon of coffee concentrate) for a richer, less sweet center. ### Cardamom Coffee Twist Add 1/4 teaspoon ground cardamom to the dough and a pinch to the filling for a warm, aromatic counterpoint that pairs beautifully with Vietnamese-style coffee. ## Notes These sandwich cookies shine at brunches, gift boxes, or any gathering where you want a dessert that tastes like a coffee shop treat. Home bakers will love the make-ahead dough and the visual impact of neatly sliced rounds for perfect, share-worthy stacks. ### Storage and Make-Ahead Store assembled cookies in an airtight container at room temperature for up to 3 days, or refrigerate for up to 1 week—bring to room temperature before serving to revive the buttercream. Unfilled cookie rounds freeze well for up to 2 months; thaw completely, then fill and assemble. If freezing assembled cookies, layer parchment between cookies and thaw in the refrigerator to avoid condensation on the buttercream. ### Serving Suggestions These cookies shine with a cold Vietnamese iced coffee (cà phê sữa đá) or a bold black espresso to match their coffee intensity; a milky latte will soften the sweetness. For a contrast of flavors, serve with segmented oranges or salted roasted peanuts, and present on a dark slate dusted lightly with cocoa for dramatic photos and a tactile contrast. ## Frequently Asked Questions ### Can I use regular instant espresso instead of Vietnamese-style coffee? Yes—regular instant espresso or instant espresso powder works fine, though Vietnamese-style coffee tends to have a slightly smoky, chocolatey edge. Adjust the amount to taste and bloom it the same way for maximum aroma. ### My dough is crumbly and won’t come together—what should I do? Add a teaspoon of the cooled coffee concentrate or an extra beaten egg yolk, a little at a time, until the dough just holds together; avoid overworking the flour which makes cookies tough. ### Why did my cookies spread and lose their round shape? Most likely the butter was too soft when you formed the logs or the logs warmed while slicing; chill the dough until firm and keep slices cold on the baking sheet before baking to preserve shape. ### The filling feels too sweet—how can I balance it? Stir in a pinch of fine sea salt or 1–2 teaspoons of unsweetened cocoa powder, or fold in a tablespoon of mascarpone to tame sweetness while keeping a creamy texture. ### Can I make the cookies larger or smaller, and how does baking time change? Yes—thinner 1/8-inch slices will take less time (8–10 minutes) and be crispier, while thicker 1/3–1/2-inch rounds need 12–14 minutes and will be chewier; watch edges for set and centers for slight softness. ## Related Recipes and Guides - [Yuzu Matcha Gelato](https://www.topshelf.recipes/recipes/yuzu-matcha-gelato) - [Sicilian Pistachio Gelato](https://www.topshelf.recipes/recipes/sicilian-pistachio-gelato) - [Ninja Slushy Soft Serve Mango Sorbet Bowl with Lime](https://www.topshelf.recipes/recipes/ninja-slushy-soft-serve-mango-sorbet-bowl-lime) - [Ninja Keto Avocado Lime Soft Serve — Low Sugar Slushy](https://www.topshelf.recipes/recipes/ninja-keto-avocado-lime-soft-serve-low-sugar-slushy) - [Easy Peanut Butter Bars](https://www.topshelf.recipes/recipes/easy-peanut-butter-bars) - [Chocolate Peanut Butter Chex Mix](https://www.topshelf.recipes/recipes/chocolate-peanut-butter-chex-mix) - [Grilled & Campfire Seasonal Sweets: 12 Crowd‑Favorite Desserts and How to Make Them Year‑Round](https://www.topshelf.recipes/articles/grilled-campfire-seasonal-sweets-12-recipes-year-round) - [Summer Weeknight Grilling Playbook: 4-Week Rotating Meal Plan with Quick Seasonal Recipes, Make‑Ahead Sides & Grill‑First Desserts](https://www.topshelf.recipes/articles/summer-weeknight-grilling-playbook-4-week-plan) - [Gluten-Free Weeknight Grilling Plan](https://www.topshelf.recipes/articles/gluten-free-weeknight-grilling-plan)
