Kinder brownies are rich, cocoa-dark squares folded with chopped Kinder milk chocolate and topped with crunchy Kinder Bueno pieces. Melted chocolate and brown sugar make the centers fudgy, while a measured bake and a full cooling period help the brownies slice neatly.
Ingredients
- ¾ cup (170 g) unsalted butter, cut into pieces
- 6 oz (170 g) semisweet or dark chocolate, chopped
- 1 cup (200 g) granulated sugar
- ½ cup (100 g) packed light brown sugar
- 3 large eggs (about 150 g without shells), at room temperature if convenient
- 1 teaspoon (5 ml) vanilla extract
- ¾ cup (95 g) all-purpose flour, spooned into the measuring cup and leveled
- ⅓ cup (30 g) unsweetened cocoa powder
- ⅓ teaspoon (2 g) fine salt
- 5.3 oz (150 g) Kinder milk chocolate, roughly chopped
- 2 twin-bar packs (about 3 oz / 86 g total) Kinder Bueno, broken into bite-size pieces
Instructions
- Prepare the pan and oven. Set a rack in the center of the oven and heat it to 350°F (177°C). Line a 9-inch (23 cm) square metal baking pan with parchment paper, leaving enough overhang on two sides to lift out the brownies later. Lightly grease the exposed sides of the pan if they are not nonstick. The listed 25 minutes of prep includes preheating, measuring, and mixing.
- Melt the butter and chocolate. Put the butter and semisweet chocolate in a heatproof bowl. Set the bowl over a saucepan of barely simmering water, making sure its base does not touch the water, and stir until smooth. Alternatively, microwave in 20-second bursts, stirring between each, until melted. Let the mixture stand for a few minutes so it is warm rather than piping hot; very hot chocolate can cook the eggs when they are added.
- Mix in the sugars and eggs. Whisk the granulated and brown sugars into the chocolate mixture until glossy and evenly combined. Add the eggs one at a time, whisking well after each, then whisk in the vanilla. A brief, vigorous whisk helps create a delicate shiny top, but stop once the mixture looks cohesive; prolonged whipping can make the brownies more cake-like.
- Add the dry ingredients. Sift or sprinkle the flour, cocoa powder, and salt over the bowl. Fold with a flexible spatula just until no dry streaks remain. Scrape along the bottom and corners of the bowl as you fold, since pockets of flour can otherwise remain hidden. Avoid beating the batter after the flour goes in.
- Fold in the Kinder chocolate. Add the chopped Kinder milk chocolate and fold just enough to distribute it. Scrape the batter into the prepared pan and spread it evenly into the corners. Scatter the Kinder Bueno pieces over the top, pressing them in lightly so they stay in place without disappearing completely into the batter.
- Bake and check the center. Bake for 30 minutes. The edges should look set and the center should be moist but not liquid; it may move slightly when the pan is nudged. For egg safety, check the center with a food thermometer: USDA FSIS recommends that egg dishes reach a safe minimum of 160°F (71°C). Insert the thermometer into a central area without touching a large piece of chocolate. If it has not reached that temperature, bake for another 2 minutes and check again. Do not rely on a completely clean toothpick, which can overbake a fudgy brownie.
- Cool before slicing. Set the pan on a cooling rack and leave the brownies undisturbed for 90 minutes. Lift them out using the parchment and cut into 16 squares with a sharp knife, wiping the blade between cuts for tidy edges. The cooling time is important: hot brownies are fragile, and the chocolate pieces need time to firm up.
Tips
- Measure flour carefully. Scooping directly from the bag can pack too much flour into a cup and make the brownies dry. For the most consistent result, weigh 95 g; if using cups, spoon flour into the measure and level it without pressing down.
- Choose the right chocolate. Semisweet or dark baking chocolate balances the sweet milk chocolate pieces. If you only have milk chocolate for the melted base, use it, but expect a sweeter, softer-tasting brownie; a darker cocoa powder or a pinch more salt can help balance the flavor.
- Keep the batter thick and avoid overbaking. Fold the flour in gently, and start checking at 30 minutes. A toothpick may pick up melted chocolate and still be misleading, so look at the set edges and use the center-temperature check rather than baking until the pick is dry.
- Plan for clean cuts. Let the whole slab cool fully before cutting. For especially neat squares, chill it for 20 to 30 minutes after the required cooling period, then use a warm, dry knife; chilling is optional and is not included in the recipe timing.
Serving Suggestions
Serve the brownies at room temperature when you want the center soft and the pieces of milk chocolate tender. For a dessert plate, add a scoop of vanilla ice cream or a spoonful of lightly whipped cream and a few fresh berries to offset the richness. A small drizzle of warmed chocolate sauce is another option, though the brownies are sweet enough to serve plain with coffee, tea, or a glass of cold milk.
If serving a crowd, cut the slab into 16 generous squares or make 24 smaller portions. A thin, sharp knife gives the best-looking pieces, especially where the Bueno pieces sit on top. Let the brownies stand at room temperature for 10 to 15 minutes after taking them from the refrigerator if you prefer a softer bite.
Variations
Use a different Kinder topping: Replace the Kinder Bueno with an equal weight of chopped Kinder milk chocolate. The top will be smoother and less crunchy, while the chocolate flavor stays similar. You can also use a mixture of both, keeping the total amount of Kinder pieces close to 236 g so the batter is not overloaded.
Add nuts: Fold ½ cup (about 60 g) toasted hazelnuts into the batter, reducing the chopped Kinder chocolate by the same volume if you want to keep the pieces easy to distribute. Hazelnuts pair naturally with the wafer-and-hazelnut filling in Bueno, but they make the brownies unsuitable for anyone avoiding tree nuts.
Make them without Bueno: If Bueno is unavailable, top the batter with 3 oz (85 g) chopped milk chocolate or use extra Kinder chocolate. You will lose the wafer crunch and hazelnut filling, but the brownies will still have the intended fudgy chocolate base. For a less sweet result, leave off the topping and serve the plain chocolate brownies with fruit.
Use a different pan: An 8-inch (20 cm) square pan makes thicker brownies and will need additional baking time; check the center temperature and doneness rather than relying on the 30-minute timing. A 9-by-13-inch (23-by-33 cm) pan makes thinner brownies, which will bake faster, so begin checking early. Metal pans brown more predictably than glass.
Storage and Reheating
Cool the brownies, then refrigerate them in an airtight container within 2 hours of baking. They keep well for 3 to 4 days in the refrigerator; separating layers with parchment helps prevent the sticky tops from clinging together. Refrigeration firms the chocolate and gives the squares a dense texture, so let a portion stand at room temperature briefly if you prefer it softer.
For longer storage, wrap individual portions or the cooled slab tightly and freeze for up to 2 months for best quality. Thaw in the refrigerator or at room temperature while still wrapped to limit condensation. To reheat a refrigerated or thawed portion, warm it briefly in the microwave and check that leftovers reach 165°F (74°C), the USDA FSIS reheating temperature; a thermometer is the reliable check. Heating that thoroughly can soften or dry the brownie, so serve it with ice cream or sauce if the texture is less fudgy.
Frequently Asked Questions
How do I know when Kinder brownies are done?
Look for set edges and a center that is moist but not liquid. Brownies can still look soft when ready, and melted chocolate on a toothpick does not necessarily mean the batter is raw. For this recipe, use a food thermometer to confirm the center reaches 160°F (71°C), then stop baking so the edges do not become dry.
Can I make the batter ahead?
It is best to bake the batter soon after mixing. If it sits for a long time, the flour absorbs moisture and the batter thickens, which can change how evenly it bakes. For make-ahead convenience, bake the brownies, cool them completely, and refrigerate or freeze the finished squares instead.
Can I use a different size pan?
Yes, but pan size changes the thickness and baking time. A smaller pan produces a thicker slab that needs longer; a larger pan produces a thinner one that finishes sooner. Keep the oven temperature the same, begin checking early if the layer is thin, and use the center-temperature and visual cues rather than assuming the original 30 minutes will apply.
Why did my brownies turn out cakey?
Too much flour, excessive mixing after adding flour, or baking for too long can all make brownies more cake-like. Weigh the flour if possible, fold only until the dry ingredients disappear, and remove the pan once the center is set and reaches the stated safe temperature. Also check that the oven is not running hotter than its setting.
Can I leave out the Kinder Bueno?
Yes. Use chopped Kinder milk chocolate or another milk chocolate bar in its place, or simply omit the topping. Bueno contributes wafer crunch and a hazelnut cream center; replacing it with plain chocolate keeps the brownies sweet and chocolatey but changes the texture.
Can I make these gluten-free?
Use a cup-for-cup gluten-free flour blend intended for baking, measuring the same 95 g by weight if the package allows. Results vary by blend, and the brownies may be slightly more delicate. Check the labels on the chocolate and candy as well, since ingredients and cross-contact information can vary by product.
