Giant Bakery-Style Kinder Bueno Cookies with Molten Hazelnut Core

These giant bakery-style cookies are the ultimate indulgence: a crisp, caramelized edge gives way to a soft, chewy center that hides a molten hazelnut cream core. Each cookie is packed with a frozen disc of chocolate hazelnut spread and topped with a fresh piece of Kinder Bueno for an extra crunch. Baked at a high temperature for just 11 minutes, they deliver a crackly exterior and a gooey, decadent filling that flows out as you pull them apart. Perfect for sharing—or not.

Imagine breaking open a warm, oversized cookie and watching rich hazelnut cream and melted chocolate pool outward, while crispy wafer layers crunch under your teeth. That’s exactly what these giant Kinder Bueno cookies deliver. The recipe starts with a dense, buttery dough made from cold European butter and both dark brown and caster sugars, giving it a deep caramel flavor and a satisfying chew.

A frozen disc of chocolate hazelnut spread is sealed inside each portion, and after a quick bake at 390°F, the center turns molten while the edges become beautifully caramelized. A final press of a fresh Kinder Bueno piece on top adds texture and an unmistakable hazelnut-chocolate hit. These cookies are pure comfort, engineered for maximum drama and flavor.

Ingredients

Why this recipe works

The method relies on a few key techniques to achieve the perfect texture. Using cold butter and cold eggs keeps the dough dense and prevents it from spreading too much in the oven, resulting in thick, bakery-style cookies.

The high oven temperature—390°F—causes the edges to caramelize quickly while the center remains slightly underbaked, creating that coveted contrast between crisp exterior and soft, gooey interior. The frozen hazelnut cream disc is crucial: it stays solid during the short bake time, then melts as the cookie cools, creating a molten core that flows beautifully when the cookie is broken open.

The choice of ingredients also plays a vital role. European butter has a higher fat content and lower water content than regular butter, which contributes to a richer flavor and a more tender crumb. Dark brown sugar adds moisture and a hint of molasses, while caster sugar helps with browning and crispness.

The combination of vanilla bean paste and the hazelnut spread enhances the overall aroma, making these cookies irresistible. Finally, pressing a fresh Kinder Bueno piece onto the hot cookie ensures that the chocolate softens slightly, adding a delightful textural contrast without melting completely.

Notes and substitutions

For the best results, use high-quality European butter, such as Plugrá or Kerrygold, and make sure it is truly cold when you start. The dough should be mixed until just combined—overmixing can develop too much gluten and result in tough cookies. Chilling the dough is not optional; it allows the flavors to meld and prevents the cookies from spreading too thin. If you don’t have caster sugar, you can process granulated sugar in a food processor for a few seconds to achieve a finer texture.

The chocolate hazelnut spread must be frozen into discs before use. To do this, line a small plate with parchment, drop teaspoonfuls of the spread to form 8 discs, and freeze for at least 2 hours, or overnight. If the spread is too soft to handle, freeze it for 30 minutes first.

For the topping, any chocolate wafer bar with hazelnut cream will work, but the original Kinder Bueno provides the perfect balance of crisp wafer and creamy filling. If you prefer a more intense hazelnut flavor, you can add a handful of chopped toasted hazelnuts to the dough.

• European butter: Unsalted butter (use cold, and increase salt to 3/4 tsp if using unsalted)
• Chocolate hazelnut spread: Any hazelnut cocoa spread; for a more intense hazelnut flavor, add 1/4 cup finely chopped toasted hazelnuts to the spread before freezing
• Vanilla bean paste: 2 tsp vanilla extract or the seeds from 1 vanilla bean
• Kinder Bueno bars: Any chocolate wafer bar with hazelnut cream, or use 8 chocolate truffles for a different texture
