Emma's coffee brand meets cookie trend! ☕🍪 These iced cookies taste like her signature iced matcha lattes. Matcha sugar cookies with coffee-cream cheese frosting. The green and brown marbling looks exactly like her Instagram aesthetic.
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. Soften butter for easy creaming—this is key for a crisp yet tender cookie.
Cream the 0.5 cup of unsalted butter and 0.75 cup of granulated sugar in a mixing bowl until light and fluffy, about 2–3 minutes. Beat in 1 egg and 1 tsp vanilla extract until fully blended.
In a separate bowl, whisk together 1.5 cups all-purpose flour, 1.5 tbsp matcha powder, 0.5 tsp baking powder, and 0.25 tsp salt. Gradually add to the wet mixture, mixing just until a soft, vivid-green dough forms.
Scoop dough into 8 portions. Shape each into a puck; chill in the fridge for 30 minutes for optimal texture and to preserve the green color. Bake for 10–12 minutes; cookies should be set at the edges but still soft in the center for that classic Chamberlain softness.
While cookies cool, make the coffee-cream cheese frosting: beat 4 oz cream cheese and 2 tbsp butter together until smooth. Add 0.75 cup powdered sugar, 0.5 tsp vanilla extract, and 1.5 tsp instant espresso powder. Beat until fluffy, adding 1 tbsp milk if needed for a spreadable consistency.
Frost cooled cookies generously and, for an Instagram-style marbling, swirl remaining matcha powder and a little dissolved espresso atop the frosting with a toothpick.
Copycat tip: Using high-quality Japanese matcha and a bold espresso powder replicates Emma’s signature latte flavor and aesthetic. Customizing sweetness or intensity at home beats store-bought every time!
