Preheat the oven to 160ºC fan / gas mark 4/ 356ºF.
Grease the Bundt tin
Greasing the bundt tin well is so important.
Melt a tablespoon of butter in short bursts in the microwave. (Use the same butter that you are using in the cake).
Paint butter into the Bundt tin with a pastry brush. Then dust it with plain flour which helps to find any places on the tin I’ve missed to grease. Repeat if you find anywhere that isn't greased.
Making the chocolate bundt cake
In the mixer or by hand cream together the butter and sugar until fluffy.
Add the eggs one at a time. Mix between additions.
Add the Alpro chocolate soya milk into the butter/sugar/egg mixture and mix well.
In a separate bowl measure out and sieve the flour, bicarbonate of soda, salt and cocoa powder together.
Mix the flour/cocoa powder mixture in slowly until all the flour has disappeared.
Put half the mixture in the tin.
In the remaining half of the mixture, add in the chocolate chips. (The chocolate chips will sink so adding them to the top half will stop them from sinking to the bottom and ruining the decorative bundt shape)
Add the second half of the mix to the tin. Gently tap the Bundt tin onto the work surface to release any large air bubbles.
Bake in the centre of the oven for about 1 hour 15 minutes or until a skewer comes out clean. When the cake pulls away from the edge of the tin the cake is ready.
Be patient and allow the cake to cool for 20-30 minutes in the tin before turning out.
Decorating the chocolate Bundt cake
Allow the cake to cool before icing.
Place the chocolate, cream and butter into a bowl and place over hot water (don't let the bottom of the bowl touch the water) and allow the mix to melt together. Keep it on a low heat to allow it to melt slowly.
When it's all melted and mixed together, leave to cool and thicken for 20 minutes for a maluable chocolate that you can spread over the top. If you want it thicker, leave it for longer. It will firm up.
Once it's ready spread it over the cool cake and decorate it with chocolate eggs and sprinkles.
