Pre-heat your oven to 160C Fan/350F/Gas Mark 4. Prepare your bundt tin by melting 5g butter and brushing it all over the inside of the tin, into every crevice and nook, this is best done with a pastry brush. Then use a sieve to dust the inside of the tin with flour. Tap the tin over your sink to remove any excess
Make the cake by mixing the baking spread (or butter) and caster sugar together in a mixing bowl until fluffy (around 3 minutes), ideally using an electric mixer
Add the eggs, vanilla extract and milk, and mix until fully incorporated
Add the self raising flour and whisk or fold in gently until you can't see any flour anymore
Add the batter into the tin and smooth it out into an even layer. Bake for 45-50 minutes, or until a thin skewer inserted comes out clean
Let the cake cool for 10-15 minutes. Remove the cake from the tin by placing a cooling rack on top of the tin and flipping it over then removing the tin. Leave to cool completely
To decorate the cake, mix the icing sugar and water together. Aim for a thick, but spreadable paste. Pipe, drizzle or spoon it over the bundt cake. Add the sprinkles while the icing is still wet
Leftovers will keep in an airtight container in a cool place for 3 days
Notes
Make sure all your ingredients (particularly the butter/baking spread and eggs) are at room temperature before you start baking.
For the best flavour, make sure to use a good quality vanilla extract and not an essence.
I used a baking spread for the cake, you can also used unsalted butter.
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.
