The blondie: everyone thinks it’s just a failed brownie—the one you make when there’s no dark chocolate left in the cupboard. In reality, it’s a pastry in its own right, with its own personality: melting, vanillic, and much softer. Add some Kinder Maxi and white chocolate into the mix, and the comparison with the brownie no longer holds at all.

Final result — Melting Kinder and white chocolate blondie squares, golden on the outside and irresistibly soft on the inside.

What you have before you is a compact slab of pale gold, almost cream, with pieces of Kinder Maxi that have melted inside and left irregular chocolatey pockets. The smell coming out of the oven is like warm milk with a touch of vanilla and that slightly toasted undertone of melted butter. The surface is matte and slightly cracked at the edges, but press it with a finger—it gives. Completely.

Why you’ll love this recipe

✓Melting texture without cheating : No need for any special technique. It’s the butter-white chocolate-flour ratio that does all the work. You stop the baking at the right moment and you get that natural soft texture.

✓The Kinder Maxi melts inside : Unlike classic chocolate chips that stay in neat pieces, Kinder Maxi almost completely disappears into the batter while baking. It leaves creamy, milky veins all over the place.

✓15 minutes of preparation, that’s it : No food processor, no chilling in the fridge, no complicated timing. A bowl, a whisk, and you’re good to go. It fits into a weeknight without stress.

✓Adaptable to what’s in the cupboard : No chocolate spread? A spoonful of dulce de leche works just fine. No Kinder Maxi? Milk chocolate chunks work too. The base remains solid regardless of the variation.

Ingredient Notes

Ingredients

All ingredients together: white chocolate, Kinder Maxi bars, chocolate spread, and a few cupboard basics for a decadent result.

White chocolate : This is what gives the blondie its characteristic color and sweetness. Use baking white chocolate or a classic bar with at least 30% cocoa butter—budget brands melt poorly and can become grainy at the slightest heat. It melts much faster than dark chocolate, so stay at a gentle simmer over a bain-marie and stir regularly.
Kinder Maxi bars : Cut them into large chunks, not small pieces. If they’re too small, they disappear completely into the mass. In large pieces, they create pockets of milky chocolate that you find when biting in. Three bars for an 18 cm mold is the right amount—present enough without unbalancing the batter.
Chocolate spread : Nutella, homemade hazelnut spread, or any version you love. It sits between the two layers of batter and stays partially melted even after baking. Drop it in small dollops rather than a thick layer—if it’s too concentrated in one spot, the center won’t bake correctly.
Butter : Unsalted butter, not semi-salted. It melts with the white chocolate and forms the entire fatty base of the batter. Don’t use margarine here—the final texture will be different, drier, with less structure when slicing.

Melt gently

Start by putting the chopped butter and white chocolate in a bowl over a bain-marie on low heat. White chocolate is temperamental. It goes from smooth to grainy very quickly if you force the heat. Stir regularly with a spatula. When the mixture is consistent, shiny, with that off-white, slightly golden color of a butter-vanilla sauce, remove from heat and let it cool slightly for a few minutes before moving on.

Attacking the batter

In a large bowl, whisk the eggs with the sugar. No need to whip them into peaks—just a consistent, slightly frothy mixture, straw-colored. Add the seeds scraped from half a vanilla bean, then pour in the cooled butter-chocolate mixture in a thin stream while stirring. If the chocolate is still too hot, the eggs will cook and you’ll get a lumpy batter. Fold in the flour with a spatula, using slow, circular motions, until the batter is dense, smooth, with a slight pearly sheen. Add the chocolate chips at the end.

The assembly

Pour half of the batter into the pan lined with parchment paper. Next, place small spoonfuls of the chocolate spread all over this first layer—the idea is to create islands, not a uniform layer. Arrange the Kinder pieces cut into large chunks on top. Cover with the rest of the batter. Smooth slightly with the spatula. If you want something visually generous, place a few extra pieces of Kinder on top before putting it in the oven.

The critical moment

Bake at 180°C for 25 to 28 minutes. The surface should be matte and slightly cracked at the edges, with a color golden like light caramel—not brown, not white, that precise golden-yellow. The center will seem not quite set. This is normal; it’s actually what we want. A toothpick inserted into the center should come out with a few moist crumbs, not clean. An overbaked blondie loses everything that makes it interesting: it becomes dry, crumbly, and that melting texture disappears completely.

And now, patience

Take the pan out of the oven and place it on a wire rack. Don’t touch anything for at least an hour. The blondie is still fragile; it continues to bake with the residual heat. Cut into a still-warm blondie and the squares will collapse, the edges will crumble, it’s discouraging. Wait until it is completely cooled—the knife blade then passes through cleanly, the squares hold well, and the inside remains melting without being crushed.

Tips & Tricks

Make your blondie the day before: after a night in the refrigerator wrapped in plastic, the texture is even better—denser, more melting, with the flavors well settled. Take it out 20 minutes before serving.
If you don’t have an 18 cm mold, a 20 cm one works, but reduce the baking time by 3 to 4 minutes—the batter is more spread out and cooks faster.
Don’t try to underbake by leaving the oven door ajar: take the pan out decisively as soon as the surface is set and the center is still wobbly. Residual heat does the rest, that’s the principle.
To warm up a cold square, 15 seconds in the microwave is enough—it regains that initial melting texture and the Kinder pockets soften again.

FAQs

How do I know if the blondie is cooked without ruining it?

The surface should be matte and slightly cracked at the edges, with a pale golden color. The most reliable test: a toothpick inserted in the center that comes out with a few moist crumbs stuck to it—not clean, but not liquid either. If the center wobbles slightly when you gently shake the pan, it’s perfect. It will finish baking with the residual heat.

Can I prepare the blondie the day before?

It is even recommended. After a night in the refrigerator in the pan covered with plastic wrap, the texture becomes denser and more melting, and the flavors are much more developed. Take it out 20 to 30 minutes before serving so it returns to room temperature.

How to store the blondie and for how long?

In an airtight container at room temperature, it keeps for 3 to 4 days without any problem. In the refrigerator, count up to a week—remember to take it out a bit before eating as it hardens slightly in the cold. You can also heat a square for 15 seconds in the microwave to regain the initial melting texture.

Can I replace Kinder Maxi with something else?

Yes. Milk chocolate chunks cut into large pieces work very well. Kinder Bueno (without the wafer) too. If you have neither, simply add more milk chocolate chips—the result will be different but still very good.

Why did my blondie come out dry and crumbly?

It is almost always a matter of baking for too long. The blondie should come out of the oven with the center still slightly wobbly—not raw, but not totally set. The other possible cause: overworking the flour, which develops the gluten and makes the texture firmer. Mix the flour just enough to incorporate it.

Can I freeze the blondie?

Yes, very well. Cut it into individual squares, wrap them in plastic wrap, and place them in a freezer bag. They keep for up to 2 months. To thaw, leave them at room temperature for an hour or microwave for 30 seconds.
