Boston Cream Cake Recipe:

My Granny has never steered me wrong. Her classic Double Chocolate Fudge Fanciful Cake was a favorite among her kids and grandkids. I tweaked her original recipe in her honor for this shortcut Boston Cream Cake.

My Granny lived in the time before cake mixes and tubs of chocolate icing lined the grocery store shelves. I can only imagine how many from scratch cakes and desserts she made. (Her Homemade Chocolate Brownies are a favorite of mine). You see, she was a homemaker who cared and fed 8 kids (with 5 being boys).

With that being said, Granny truly appreciated the convenience behind a store-bought cake mix. It’s for this reason alone that I will never apologize for using shortcut ingredients.

Easy Yellow Cake Mix Boston Cream Cake

Let’s talk about this easy Boston Cream cake:

Granny’s cake is rich.

It’s decadent.

And moist.

It’s a home-run.

I swear the cake feels like it weighs 10 pounds when you lift it.  That’s because there’s a thick, cream cheese layer that sinks to the bottom.

Traditional Boston Cream Pie consists of a round yellow cake with a custard layer in the center.  My shortcut Boston Cream Pie has the custard layer at the bottom instead.  It magically sinks to the bottom during the cooking process.

If you are wondering should Boston Cream Cake be refrigerated?  Yes, you should cover and refrigerate due to the cream cheese layer.

  1. Your recipe for cream cheese doesn’t call for 4 eggs but instructions line 3 says eggs. Do I add?

    1. Maredith – So sorry about that! 3 eggs in the cake and 4 eggs in the filling. We fixed the ingredient list.
