Kinder Bueno Slutty Brownies Brownies

These Kinder Bueno Slutty Brownies are my newest invention. Chocolate chip cookie dough topped with Kinder Buenos and covered with a white chocolate hazelnut swirled brownie layer. Can you even?!

What are Slutty Brownies?

Slutty Brownies are an internet invention. To be perfectly honest, I’m not a fan of the name. We’re not here for slut shaming over here on Katiecakes but that’s the name they were given so we’re stuck. I much prefer to call them Cookie Dough Layer Brownies (which is how we refer to them in the bakery). Basically, Slutty Brownies are a layer of chocolate chip cookie dough, traditionally they then contain a layer of Oreo cookies which is then topped by a layer of chocolate brownie. My favourite thing about them is they’re so easily adaptable. See my recipes for Jaffa Cake Slutty Brownies, Easter Slutty Brownies and Creme Egg Slutty Brownies.

Why these Kinder Bueno Slutty Brownies are the best!

  • They take the original slutty brownie and amplify them to 1000!
  • They’re thick, fudgy and oh so indulgent.
  • Bring them to a party and people will be talking about them for weeks!
  • They’re much easier to make than they seem, you can even use boxed mixes if you’re that way inclined.
  • You can’t go wrong with Kinder in a dessert! Trust me!

Tips for making Kinder Bueno Slutty Brownies:

  • Can I eat the cookie dough raw? – No! This cookie dough contains egg so it’s not advised to eat it raw.
  • Can I use all caster sugar in the cookie dough? – You can but it would change the texture slightly and it wouldn’t be as tasty. The brown sugar adds a delicious caramel flavour and a chewier texture.
  • Where can I find White Chocolate Hazelnut Spread? – I got mine in Lidl (of all places!) but I’ve seen this kind of spread in Morrisons and M&S. Or you can always find it available online. If you can’t find any, Nutella works just as well.
  • Can I use milk chocolate in the brownie layer? – No, milk chocolate is far too sweet and your brownie will come out super gross. Always use plain chocolate when making brownies. You can use a 70% solid chocolate if you’re not keen on the higher percentages but I wouldn’t recommend going any lower than that.
  • Can I freeze these brownies? – Yes! You can freeze the whole tray or individual brownies wrapped in a double layer of cling film for up to 3 months. Just defrost at room temperature.
  • Can I make them Gluten Free? – Yes, just use Doves Plain Flour Blend. It’s the best I’ve used for baking.
  • Do I have to call them Slutty Brownies?! I’m baking these for kids you know! – No you don’t have to use that name. In fact I kinda hate it myself but unfortunately that’s what people search for and us bloggers are a slave to SEO . You can call them Kinder Bueno Cookie Dough Brownies, a much nicer name.

HERE’S WHAT YOU’RE GOING TO NEED:

  • Unsalted Butter – Make sure your butter is at room temperature before you start, this makes blending the sugar much easier.
  • Light Brown Sugar – I prefer to use light brown sugar as it gives a subtle caramel flavour to the cookies. You can use caster in place but the cookies won’t be quite as tasty.
  • Caster Sugar – A little bit of caster sugar helps with the structure of the cookies.
  • Eggs – Always large, always free range!
  • Vanilla Extract – Always use a pure vanilla extract, there’s nothing worse than vanilla essence. Yuck!
  • Plain Flour – Sometimes called All Purpose flour.
  • Chocolate Chips – You can use any kind of chocolate chip you like, plain, milk or white. You can even use a bar of chocolate chopped up small.
  • Kinder Buenos – I used the white Kinder Buenos in this recipe but the plain chocolate ones would also be great. Yo
  • Plain Chocolate – I use plain chocolate, 72-75% is a good landing point when it comes to baking. Use a higher cocoa solids percentage if you don’t like it too sweet.

Kinder Cookie Dough Brownies


Description

These Kinder Bueno Slutty Brownies are my newest invention. Chocolate chip cookie dough topped with Kinder Buenos and covered with a white chocolate hazelnut swirled brownie layer. Can you even?!


Ingredients

Scale

For the cookie dough layer:

  • 225g unsalted butter, softened
  • 200g soft, light brown sugar
  • 150g caster sugar
  • 2 eggs
  • 1tsp vanilla extract
  • 350g plain flour
  • 100g chocolate chips
  • 4 Kinder Bueno bars

For the brownie layer:

  • 125g unsalted butter
  • 150g dark chocolate
  • 175g caster sugar
  • 2 large eggs
  • 80g plain flour
  • 5tbsp White Chocolate Hazelnut Spread

Instructions

  1. Preheat oven to 170C and line a 8×8″ square brownie tray with baking parchment. Set aside.

For the Cookie Dough Layer:

  1. For the cookie dough layer, cream together the butter and sugars till light and fluffy.  Add the eggs one at a time, mixing between each addition followed by the vanilla extract.  Add the flour and mix until just combined, stir through the chocolate chips.  Press the dough into your prepared pan in an even layer.  Place the Kinder Bars in rows over the cookie dough, breaking some up to fill any gaps, and press down slightly so they sink in a little bit.  Set aside while you make the brownie layer.

For the Brownie Layer:

  1. In a large saucepan over a low heat melt the butter and chocolate together.  Add the sugar and stir together.  Crack the eggs into a large jug and whisk up, slowly pour the eggs into the chocolate mixing as you go until combined.  Add the flour and stir until the white streaks just disappear.  Pour the brownie mixture over the cookie dough and Bueno layer making sure everything is covered. Drop spoonfuls of the white chocolate hazelnut spread over the top of the brownie and swirl it through with a sharp knife. Bake for 35 minutes, until just set.
  2. Allow to cool in the fridge over night before cutting into 16 squares.
