A homemade French Custard Cake with blueberries, lays on a Biscoff Crust and is topped with lemon frosting and a homemade blueberry sauce.

So remember on Monday when I talked about that delicious blueberry sauce and promised that I will share the magnificent cake I made with the extra blueberries I had on hand? Well, here it is, the most silky and indulgent French Custard Cake I have ever had. I love French desserts, they are creamy, decadent, rich and always look so fancy and put together, while the ingredient list is usually very simple.

Well, this cake is no exception, its silky smooth, baked to perfection, with a subtle vanilla flavor from the whipped mascarpone, juicy blueberries are added to the batter on the most amazing biscoff crust.

So when my husband asked me what I am going to make with the blueberries, I said CAKE – obviously. And since we are in the middle of planning a short getaway to Paris for his birthday in October, I felt I must make something French inspired to celebrate.

French desserts are romantic, indulgent, sweet and smooth, this cake is no different, this french custard cake is actually much better. To make it even better, I made a biscoff crust that is so buttery and sweet, and attains a caramelized flavor and taste after is baked that pairs so well with the delicate custard cake.

I wanted the cake to taste very fresh, the custard itself doesn’t feel heavy, since its made with just a little flour and few eggs, its very creamy and light, I added some lemon zest for some summery brightness and freshness and also 2 cups of blueberries. Every delicious bite of this creamy goodness is followed by a tart burst of juicy blueberries, a subtle lemon flavor and a delicious caramelized crumble from the biscoff crust.

This cake is perfection, I also went ahead and topped it with some lemon mascarpone buttercream and homemade blueberry sauce. The buttercream is so perfect here, its like another creamy layer, but so different in texture from the custard, it adds another decadent level of texture and fresh flavor, the lemon flavor works in harmony with the vanilla blueberry sauce to bring this dessert together.

You have it all here, creaminess, deliciousness, freshness and decadence, all in one beautiful french custard cake, that looks fabulous and it’s actually very easy to make. You can totally skip the buttercream if you want to keep the cake a little lighter, but make sure you top it with that homemade blueberry sauce!

This French custard cake is the ultimate summer dessert that you must try, we surely loved it and devoured every single crumb!And since we are planning our trip to Paris if anyone has any recommendations of things we must try, places we should go, please let me know!
