For me, and I'm sure a lot of you too, Easter is all about chocolate indulgence! And it does not get more indulgent than these Creme Egg Slutty Brownies - also known as Creme Egg Brookies. They have a layer of yummy cookie that's dotted with chopped up Mini Creme Eggs, then a layer of Creme Eggs, then a layer of rich chocolate brownie, and finally they're drizzled with white chocolate (half of it coloured orange) for that Creme Egg 'splatter' look! They are absolutely delicious and are the ultimate Easter baking treat!

Ingredient Tips & Equipment Information

Make sure your eggs and the butter for the cookie dough are at room temperature before you start baking. The butter for the brownies can be cold for this recipe, as you are going to melt it anyway. It will just take slightly longer to melt.
I used unsalted butter for this recipe.
I used light brown soft sugar for the brownies and cookie dough, but you can also use caster sugar.
For the best results, use a good quality food colouring for the white chocolate topping. My favourite brands are Sugarflair and Pro Gel.
Although I provide cup measurements, I highly recommend weighing your ingredients out using digital kitchen scales. It is the most accurate way to measure ingredients and will ensure the best results. Digital scales are very low cost and can be purchased for around £12 ($16.50) .
For teaspoon (tsp) and tablespoon (tbsp) measurements, please use measuring spoons and not the type of spoons you eat with. Again this will ensure accuracy and provide the best results.

How to make Creme Egg Slutty Brownies

To make the cookie dough layer, mix butter and light brown soft sugar together, then add milk and vanilla extract. Then mix in plain flour, salt and chopped up Mini Creme Eggs.

Press the dough into the bottom of your tin. Add halved Creme Eggs over the top, then put the cookie dough in the fridge for 30 minutes. For the brownie layer, melt butter and dark chocolate together in a pan on a low heat. In a mixing bowl, whisk together light brown sugar, vanilla extract and eggs. Then pour the chocolate mixture into the egg mixture and whisk to combine.

Then stir in plain flour and cocoa powder. Add the brownie mixture on top of the cookie dough, and then bake for 45 minutes. Leave to cool completely in the tin. To decorate, melt the white chocolate then split it in half. Colour one half with orange food colouring. Drizzle both chocolates all over the brownies.

Why are they called Slutty Brownies?

I have to say I am not a huge fan of the name, I much prefer the terms brookies or ultimate cookie dough brownies (both better names if you're making them with your kids!) But the internet has grasped onto the term and it's now the most well known way to refer to this combination. From my research, the concept of Slutty Brownies emerged online in May 2011. Both KevinAndAmanda.com and The Londoner are credited with being the first to post recipes. Their recipes both use box mixes, which I personally cannot endorse as I am very much a make it from scratch girl! However, myself (along with thousands of others I'm sure) will always be grateful for them for introducing this recipe concept to the world!

How do you cut Creme Eggs in half?

The best way to do this is to use a large sharp knife, find the seal where the two halves of egg have been stuck together (sometimes there is a slight crack that can start of your cut), and saw the knife through the chocolate. Try not to just push down, as this can crack the chocolate. If is very likely that you won't get perfect halves for all of your eggs, but you can still use them as they are all tightly fitted together over the cookie dough base which holds the half together, or you can eat them!

What size tin do you need to make this recipe?

This recipe is designed for an 8″ square tin. These brownies are very rich and indulgent so when cut into 16 pieces, this size tin gives you a good portion size. If you only have a 9" square tin, please be aware that you will need to increase the ingredient quantities by 25%. They may also need slightly longer to bake. I really do recommend using an 8" square tin though for the best results.

How should the brownies be stored and can they be frozen?

They should be stored in an airtight container, or covered on a plate, in a cool place for 3 days. You can also freeze the brownies. Once they are fully cool, wrap them well and freeze for up to 3 months.

Can the brownies be made gluten or dairy free?

Yes! For gluten free you can replace the plain flour with a gluten free plain flour blend. You may like to add ¼ tsp xanthan gum to the cookie dough for better texture. For a dairy free version, use a dairy free baking spread instead of butter, dairy free milk and a dairy free dark chocolate for the brownies. You will also need to use a dairy free alternative to Creme Eggs, Mummy Meagz Chuckie Eggs are a brand I know of.

More tips for making the Creme Egg Slutty Brownies:

If you want to reduce costs when making this recipe, you could use Mini Creme Eggs for the filling, or a mixture of Mini and regular sized Creme Eggs.
The white chocolate decoration on top is optional, but it does look really fun!
