What you need to make this recipe

When I say the recipe is easy, I really mean it; and not only that there's no fancy ingredients either. Here's what you'll need to get ready...
- Dark Chocolate - I prefer to use a semi-sweet dark chocolate for this recipe, about 40-50% cocoa. It will give you the rich, deep chocolate flavour you are after without masking the Bueno hazelnut flavour. You can use a higher cocoa percentage like 70% if you prefer but you might find the brownies taste a slightly bitter. Try to avoid milk chocolate as this will have added sugar which can affect the texture and taste of your brownies, making them too sweet.
- Kinder Bueno Bars - They wouldn't be Bueno brownies without them. With a crispy wafer filled with hazelnut cream and coated in chocolate, they add a crunch to your fudgy brownies. I used the milk chocolate ones, but you could try the white chocolate version as well.
- Kinder Chocolate Bars - I decorated the top of my brownies with chunks of my favourite Kinder Chocolate; you could swap this for extra Bueno pieces if you wanted too. I also melted some leftover chocolate to drizzle over the top.
The best thing about these Kinder Bueno brownies are their simplicity, and while there's no fancy ingredients there's also no fancy equipment needed. Everything you'll need will be right there in the kitchen cupboard.
All you'll really need is a large mixing bowl and a hand held mixer, or a stand mixer if you have one. And if you're after an arm workout, grab a balloon whisk.
You'll also need...
- Brownie Pan - You'll need either or square or rectangle brownie pan to bake the recipe in, the choice is yours. If you don't have a brownie pan, you can use a cake tin. I use a metal 9-inch square tin, it bakes so much better than a silicone mould.
- Baking Parchment - Even if you have the best non-stick baking tin ever, you'll want to line it with baking parchment when baking brownies. Not only does it keep you pan in great condition, it makes it so much easier to lift the brownies out when they're cooled down.
- Offset Palette Knife - If there's one thing I can't recommend investing in enough, it's an offset palette knife; I love mine. It's ideal for getting a really smooth top without getting your fingers in the filling. But if you don'thave one, just use the back of a spoon.
How to make the brownies
Full measurements and instructions can be found in the recipe card
The brownie batter is whipped up in a matter of minutes so grab everything you need and lets bake....
Start off by melting the chocolate and the butter together in a heatproof bowl. You can do this either by placing the bowl over a pan of simmering water, or in the microwave in 30 second blasts (1-2). Pop the melted mixture to one side to cool down.
In the meantime, add the eggs and caster sugar into a large mixing bowl and whisk with a handheld mixer for about 3 minutes, until they are thick, pale and fluffy (3-4).
Add the melted chocolate to the whisked egg and a teaspoon of vanilla extract. Then with a rubber spatula mix until well-combined (5).
Next up, sieve together the plain flour and cocoa powder and add to the chocolate mixture. Gently fold the everything together, making sure that all the flour is incorporated (6-8). The batter should be thick and fudgy, just like it should be!
Pour the half the brownie batter into a lined brownie pan and spread out to an even layer. Scatter over the Kinder Bueno pieces, before add the remaining batter on top and levelling off (9-11).
Add a final layer of Kinder chocolate chunks and you're ready to bake your Kinder Bueno brownies for 30-35 minutes at 180C/ 350F (12).

Recipe top tips and notes
I'll hand on my heart state that this recipe is foolproof! But I'll also admit that it can have its moments. Take it a tweak too far and you'll end up with a cakey brownie or one that's completely squidgy.
To make sure you get the perfect brownie everytime, here are my top tips...
- Make sure your eggs are at room temperature - Eggs straight from the fridge are harder to whisk and get nice and frothy. So get them out of the fridge in plenty of time before you want to make the brownies. Alternatively, pop them in warm tap water for 10 minutes and they will come up to temperature.
- Let the melted chocolate cool down - You're going to be adding the melted chocolate to the eggs, so it's super important that you make sure the chocolate has cooled. If the don't the hot chocolate will begin to cook the eggs and you'll end up with scrambled eggs instead!
- Don't be tempted to overbake the brownies - I always go on the side of underbaking my brownies. Remember that when you take them out of the oven, they will continue to bake with the residual heat. Try testing the brownie edge with a skewer, about 5 minutes before the bake time is up. If it comes out with moist crumbs attached, then its just right.
- Make sure you let the brownies cool fully - I know they smell amazing, and it's so tempting to get stuck straight into the brownies straight from on the oven; but be patient and wait for the brownies cool. Leave them to cool in the the pan for 10-15 minutes, then using the baking parchment lift them out and fully cool on a wire rack. You'll get perfectly fudgy brownies rather than ones that fall apart.
Save for later!
