Giant Bakery-Style Kinder Bueno Cookies with Molten Hazelnut Core

These giant bakery-style cookies are everything you want in a dessert: crisp caramelized edges, a chewy center, and a surprise molten hazelnut cream core. Chopped Kinder Bueno bars add crunchy wafer bits and creamy chocolate in every bite.

The dough comes together quickly with cold butter and a mix of cake and bread flours for the perfect texture. Stuffed with frozen Nutella and baked at high heat, these cookies deliver a dramatic pull-apart moment that feels straight from a professional bakery.

This recipe transforms a classic chocolate chip cookie into an oversized, indulgent treat inspired by the beloved Kinder Bueno candy bar. The dough is made with cold European butter, dark brown sugar, and caster sugar for a dense, chewy base. A blend of cake flour and bread flour gives the cookies a tender crumb with just enough structure to hold the generous filling.

Each dough ball is wrapped around a frozen dollop of hazelnut cream, then baked until the edges caramelize and the center stays molten. The result is a cookie that looks and tastes like it came from a high-end bakery, but is simple enough to make at home.

Ingredients

Why this recipe works

Using cold butter and beating it just until combined creates a dense, thick dough that spreads less in the oven. This is the secret to cookies that are chewy in the center and crisp at the edges, rather than flat and cakey. The combination of cake flour, which is low in protein, and bread flour, which is higher, gives the cookies a tender yet sturdy structure that can hold the heavy filling without falling apart.

Freezing the Nutella in dollops before stuffing ensures the filling stays contained during baking. As the cookies bake, the frozen cream melts slowly, creating a molten core that doesn't leak out. The high oven temperature of 390°F sets the edges quickly while the center remains slightly underbaked, yielding that perfect gooey texture. Pressing a fresh piece of Kinder Bueno on top after baking adds a final touch of crunch and visual appeal.

Notes and substitutions

European-style butter, such as Plugra or Kerrygold, has a higher fat content than regular butter, which contributes to a richer flavor and a more tender crumb. If you can't find it, regular unsalted butter works fine.

Caster sugar is finer than granulated sugar and dissolves more easily, but granulated sugar is an acceptable substitute. Vanilla bean paste adds a deep vanilla flavor with visible specks; pure vanilla extract can be used instead.

Kinder Bueno bars are essential for the authentic flavor, but any crispy hazelnut chocolate bar with wafer layers can be substituted. The white chocolate chips add sweetness and creaminess; feel free to use milk chocolate chips if preferred.

The Nutella hazelnut cream must be frozen in dollops before stuffing, so plan ahead. A standard ice cream scoop makes portioning the dough easy, and a sturdy spatula helps fold the mix-ins without breaking the wafers.

• European-style butter: Use regular unsalted butter if European-style is unavailable; the cookies will be slightly less rich but still tender.
• Caster sugar: Granulated sugar works in equal measure; the texture will be marginally coarser.
• Vanilla bean paste: Substitute 2 teaspoons vanilla extract for the paste, though the specks and intensity will differ.
• Kinder Bueno bars: Any crispy hazelnut chocolate bar with wafer layers can replace Kinder Bueno; adjust sweetness to taste.
