Bakery-Style Kinder Bueno Stuffed Cookies Step-by-step instructions

Before you start

Before beginning, ensure that all ingredients are measured and ready. The butter must be cold, straight from the refrigerator, to ensure the dough remains dense.

Prepare the hazelnut cream by spooning dollops onto parchment paper and freezing them until they are solid discs; this is essential for the stuffing process.

Preheat the oven to 390°F (199°C) early so it is fully ready when the dough is prepared. Line your baking sheets with high-quality parchment paper to prevent sticking.

Instructions

Creaming the Base

1. 1Creaming the Base
   In a large stand mixer bowl, combine the cold European butter, dark brown sugar, and caster sugar. Beat on medium speed until the mixture is smooth and thick. Add the cold eggs and vanilla bean paste, continuing to beat until just combined. Ensure the butter is incorporated without over-aerating the dough to maintain a dense, bakery-style texture.
   Look for The mixture should be thick, smooth, and uniform in color.
   Tip Keep the butter cold for a better texture.

The butter and sugar mixture should reach a thick, smooth consistency. It should look pale and creamy, with no large lumps of butter remaining. This phase is crucial for the structure of the cookie, so take your time to ensure the ingredients are fully emulsified before adding the eggs.

Mixing the Dough

2. 2Mixing the Dough
   Gradually add the cake flour, bread flour, and cornstarch to the butter mixture. Mix on low speed until the flour is almost incorporated. Gently fold in the white chocolate chips and the chopped Kinder Bueno wafer bars using a silicone spatula. Do not overmix the dough once the flour is added to ensure the cookies remain soft and chewy.
   Look for The dough will be chunky and thick with visible chocolate and wafer pieces.
   Tip Use a large spatula for folding to keep the wafers intact.

The dough should look thick and chunky. When folding in the chips and wafers, ensure they are evenly distributed throughout the dough. The texture should feel substantial and hold its shape easily when scooped, indicating that the flour ratio is correct for these large, stuffed cookies.

Filling and Baking

3. 3Filling and Baking
   Divide the dough into equal portions. Flatten each portion into a disc, place a frozen disc of hazelnut cream in the center, and seal the dough tightly around it to form a ball. Arrange on a parchment-lined baking sheet. Bake at 390°F (199°C) for 11 minutes until the edges are golden and caramelized. Press a fresh Kinder Bueno piece onto the top of each cookie while hot. To ensure the eggs are fully cooked, bake until the center reaches 160°F (71°C).
   Look for The edges should be caramelized and golden brown.

   Tip Freeze the hazelnut cream discs beforehand for easier stuffing.

The cookies are ready when the edges are perfectly golden and the centers are hot and set. The hazelnut cream inside will be molten. Ensure the cookies have cooled for a few minutes on the pan so they can firm up enough to handle without breaking the delicate wafer structure.

Common mistakes

A common mistake is using room-temperature butter, which leads to excessive spreading and a greasy texture. Another error is failing to seal the dough completely around the frozen hazelnut cream disc; if there are any gaps, the filling will leak out during the baking process.

Finally, overcrowding the baking sheet can prevent proper air circulation, leading to uneven cooking and soft, pale edges that lack the desired caramelization.

How to tell it’s done

The cookies are done when the edges are visibly caramelized and golden brown, while the centers appear set but still soft. Using a food thermometer, check the internal temperature of the cookie center; it must reach 160°F (71°C) to ensure the eggs are fully cooked.

The cookies will continue to firm up slightly as they cool on the baking sheet, so avoid overbaking them, which can lead to a dry texture.
