What is the best type of cake to make on an anniversary but which too rich?

It sounds like you're looking for a cake that's celebratory but not overly heavy. Here are some ideas for cakes that fit the bill, striking a balance between deliciousness and lightness:

Lighter Options:

* Fruit cakes: A classic choice, fruitcakes can be made with lighter batters and less dense fillings. Try a citrus cake with orange zest or a berry cake with fresh raspberries.

* Sponge cakes: Sponge cakes are airy and fluffy, perfect for a celebratory occasion. You can enhance them with flavorful fillings like whipped cream and fruit.

* Angel food cake: This light-as-air cake is made with egg whites and is perfect for a special occasion. It can be topped with fresh berries or a simple dusting of powdered sugar.

* Cheesecake: While rich, cheesecake can be made in a lighter style. Try a New York-style cheesecake with a graham cracker crust or a ricotta cheesecake with a fruit topping.

* Fruit tarts: A tart filled with fresh berries or seasonal fruit is a beautiful and lighter alternative to a traditional cake.

Tips for making lighter cakes:

* Use less butter and sugar: This will help to keep the cake from becoming too dense.

* Use lighter flours: Cake flour is a good option for a lighter cake.

* Add leavening agents: Baking powder and baking soda will help to make the cake rise and become more airy.

* Use fresh fruit: Fruit adds moisture and flavor without adding too much richness.

* Make a simple frosting: A simple whipped cream or powdered sugar frosting will be lighter than a buttercream frosting.

Remember, ultimately the best cake for your anniversary is the one you and your partner will enjoy the most!
