The strawberry filling in this collab cookie is what makes it shine! Unlike artificial strawberry flavor, this tastes closer to real strawberry jam with just the right amount of sweetness. The cookie stays soft and warm (if you order delivery), with the filled center adding moisture and fruity brightness. It's like a hand-held strawberry toaster pastry but way better. 🍓🍪
Soften 1 stick butter and 2 oz cream cheese until room temperature but not melted. Beat together with both sugars (3/4 cup light brown sugar and 1/4 cup granulated sugar) until light and creamy, about 2–3 minutes.
Add in 1 large egg, 1 egg yolk, and 1 tsp vanilla extract. Mix until fully incorporated, scraping down the bowl. This creamy fat base gives Crumbl-style softness.
In a separate bowl, whisk all-purpose flour, bread flour, cornstarch, baking powder, baking soda, and salt. Add dry ingredients to wet and mix on low until just combined—do not overmix to ensure a tender crumb.
Divide dough into 8 equal pieces (about 90g each). Flatten each piece, spoon 1 generous tbsp strawberry preserves into the center, then fold dough up and around the filling, pinching to fully seal. Shape into thick rounds (about 4 inches); freeze for 30 minutes to prevent spreading.
Preheat oven to 375°F (190°C). Bake chilled cookies on parchment-lined tray for 12–14 minutes, until edges are set but centers are slightly pale—this underbake mimics Insomnia gooeyness. Cool 10 minutes on tray.
Whisk powdered sugar and milk to make a thick icing. Drizzle generously over cooled cookies. Enjoy warm for the full toasty-filling effect. (Copycat tip: Freezing dough and sealing well prevents strawberry leaks and keeps the interior molten.)
