Put the butter and the chocolate in a medium-sized heatproof bowl and set over a pan of simmering water, stirring occasionally until melted. Alternatively, cover the bowl loosely with cling film and microwave at 30 sec intervals until melted. Leave the melted chocolate mixture to cool to room temperature.

Heat oven to 180C/160C fan/gas 4. Grease a 20cm square tin with butter and line with 2 long strips of folded baking paper or foil – one running top to bottom, the other left to right then line the base with a piece of baking paper. The strips will help you lift it out later.

Break the eggs into a large bowl and tip in the caster sugar. With an electric mixer on maximum speed, whisk the eggs and sugar for around 5-8 mins or until they look thick and creamy and have doubled in size.

Pour the cooled chocolate mixture over the egg mixture, then gently fold together.

Sieve the flour and cocoa into the wet ingredients then continue to fold the mixture gently with a spatula just until everything is fully combined, try not to over-mix.

Pour the mixture into the prepared tin and carefully level the mixture with the spatula. Put in the middle of the oven and bake for 20 minutes.

Meanwhile, cut the fondant filled eggs in half and set aside then place the mini chocolate eggs into a pestle and mortar. Crush a few of the mini chocolate eggs but leave some whole. After 20 mins take the brownie out of the oven and press in the fondant eggs, cut side up. Scatter over half of the mini chocolate eggs too then put it back in the oven for a further 5 mins.

Once baked, top with the remaining mini eggs, leave to cool completely then place in the fridge for about 1hr to firm up. Lift it out of the tin using the strips of baking paper and cut into squares to serve. Decorate with little Easter chicks if you like.

Line a 20cm square brownie tin with baking parchment. Tip all the ingredients, except the mini chocolate eggs, into a saucepan set over a low heat. Stir gently until all of the sugar has melted. Turn up the heat and simmer for 10-15 mins, scraping the bottom of the pan regularly until the mixture reaches 115C on a sugar thermometer. If you don’t have a sugar thermometer, drop a teaspoon of mixture into a small bowl of cold water – if it’s ready, it will form a soft ball that can be easily flattened.

Remove the fudge mixture from the heat and leave to cool for 5 mins. Use a wooden spoon to beat the mixture for another 5 mins.

Roughly chop 100g of the mini chocolate eggs and tip these into the fudge mixture, then stir until evenly combined. Tip the fudge mixture into the prepared tin, smoothing the surface and pushing it into the corners using a rubber spatula. Scatter over the remaining mini chocolate eggs, then leave at room temperature until completely firm and set. Turn out onto a chopping board and cut into 20 squares before serving.

Heat oven to 180C/160C fan/gas 4. Line 24 holes of a mini muffin tray with paper cases. Put the butter, dark chocolate and sugar in a pan and heat it very gently, stirring all the time until the butter and chocolate have melted. Remove from the heat and leave to cool for a few mins.

Meanwhile, sift the flour, cocoa and a good pinch of salt into a large bowl. Stir in the warm, melted chocolate mixture and the beaten eggs, then add half the chocolate chips and mix until just combined.

Divide the mixture between the cases and place a mini egg into the middle of each muffin, pushing down gently. Bake for 12-15 mins until cooked but still gooey in the centre – they will continue cooking a little as they cool down. Leave to cool for 10 mins in the tin before transferring to a wire rack to cool completely.

Melt the rest of the chocolate chips in short bursts in the microwave, or in a bowl set over a pan of simmering water, stirring frequently. Leave to cool until it is quite thick, then dot a small amount on each cake and stick on some more mini eggs.

Heat oven to 190C/170C fan/gas 5. Line two baking sheets with baking parchment. Tip the butter, sugars and vanilla into a bowl. Beat with a hand-held electric whisk until pale and fluffy. Add the egg and beat again. Tip in the flour, bicarb and a pinch of salt, then use a spatula to mix together before adding the chocolate chunks and about half the crushed mini eggs (set aside the larger pieces) and mix again until everything is combined.

Scoop golf-ball-sized mounds of cookie dough onto the baking sheets, making sure you leave plenty of space between each one. (You should fit 4-6 cookies on each, so you’ll have to bake in batches to make the total 20 cookies.) Push the remaining mini egg pieces into the tops. Can be frozen at this point for up to three months. Defrost thoroughly in the fridge before baking. Bake for 15-18 mins, swapping the sheets around halfway through. For soft and chewy cookies, the cookies should be golden around the edges but still pale and soft in the middle. If you prefer a biscuit texture, you will need to bake them a little longer.

Remove from the oven and leave to cool for 10 mins before transferring to a wire rack, then bake the second batch. Continue until all the cookies are baked. Will keep in an airtight container for up to a week.
