This lemon raspberry cake is moist, fluffy, filled with a creamy, tangy raspberry curd, and frosted with a lemon raspberry cream cheese frosting. It's packed full of lemon and raspberry flavors, and is the perfect refreshing cake! The raspberry curd is so easy to make and is really the star. It's tangy, has so much raspberry flavor, and has a smooth, buttery texture. You'll need 4 ½ cups of raspberries plus a few extra for decorating. That's about 550g or 18.5 oz by weight.
