Preheat your oven 180 degrees celsius (fan-forced) and line the base and sides of a loaf tin.
Place the softened butter, caster sugar and vanilla extract into your Thermomix bowl and mix for 45 seconds, speed 3. Scrape down the sides of the bowl and mix for a further 20 seconds, speed 4 or until pale and creamy.
Turn the Thermomix onto speed 4 and remove the measuring cup. Add the eggs one at a time, leaving 5 seconds of mixing between each egg. Turn off your Thermomix.
Add the self raising and plain flour and mix for 12 seconds, speed 5 to combine. Scrape down the sides of the bowl and mix for a further 8 seconds, speed 5.
Transfer the mixture to your prepared cake tin and gently smooth the surface. Place the cake into your preheated oven and bake for 50 mins - 1 hour or until cooked when tested with a skewer.
Carefully remove the cake from the oven and allow it to cool for 10 minutes before transferring to a wire rack to cool completely.
Notes
The times in this recipe are based on butter being at room temperature (approximately 24 degrees celsius) if your butter is still quite firm (doesn't give when pressed) then the time it takes to combine with the sugar will increase.
You want the butter and sugar mixture to be pale and creamy before moving onto the next step.
After adding the eggs the mixture will look curdled, please don't worry this is completely fine!
You can bake your Pound Cake in a loaf or round cake tin, however please note the cooking time will vary.
The cake will develop a golden crust, this is normal. If you feel your cake is getting too brown, simply cover the top with some foil.
Store the cooked cake in an airtight container in a cool dry place and enjoy wishing one week.
