    White Chocolate Peanut Butter Cake with Peanut Butter Filling

    white chocolate peanut butter cake

    A Cake for Serious Peanut Butter Lovers

    Maybe I should rename this peanut butter cake  “The Must Absolutely Love Peanut Butter Cake”, since Peanut Butter is the main ingredient in the cake, filling and pieces.  I did think about using a peanut butter whipped icing.  However, I went with white chocolate whipped icing to go with the white chocolate pieces.  The white chocolate whipped icing works really well with this flavor combination.

    Decadent and Rich

    There is no doubt that this is one of the most decadent and rich cakes that I have created.  I would also put this layer cake in the “Show Stopper” category for presentation.  I love how this cake looks on top of a cake stand.   Need a centerpiece? No problem just make this White Chocolate Peanut Butter Cake.

    Cake, Filling, Pieces and Icing, Oh My

    Okay, so this layer cake doesn’t exactly fall in the easy and quick category.   There are four (4) parts that have to be completed before assembly.  Most often, I make all the elements a day or so early and then assemble on a different day.   From experience, I can tell you that assembly of layer cakes goes much better with all items are well chilled.  Also, I like to let my cakes settle a day or so before assembly.

    From Scratch Peanut Butter Cake

    I love this scratch recipe.  I took my standard butter cake recipe and changed it up for this peanut butter cake.  Basically, I swapped out some of the granulated sugar for brown sugar and added peanut butter.

    This is a reversed creamed method cake recipe.  The recipe starts with the dry (flour/sugars) ingredients.  To the dry mixture the butter is cut in, very much like pie crust or biscuits.  Then the liquids are added.  The last ingredient is the peanut butter.  I am a huge fan of the reversed creaming method.  I really like the crumb the cakes have with this method.

    You will want to pay special attention to wrapping and cooling the cake.  Unless noted, never cool cakes in the pan.  As soon as you can turn a cake out (3 to 5 minutes) and wrap loosely in plastic food wrap.  Then let the cakes cool on the counter.  Once cool, move to either the refrigerator or freezer until assembly.

    The Peanut Butter Filling

    The peanut butter filling for this peanut butter layer cake is also the filling for my peanut butter pie. I’ve scaled down the amounts to use as a cake filling.  Make sure you really chill this filling before using.  Chill at least 4 hours or overnight.   Again, I usually make the filling a couple days before I assemble the cake.

    White Chocolate Pieces

    You have a couple options for the filling and topping pieces.  I’ve been in a pinch and used chopped Reese’s white chocolate cups for the top and the filling.  However, I prefer to make my own.  You can find the complete step-by-step directions here :  Learn to Make Chocolate Peanut Butter Pieces.

    White Chocolate Whipped Pudding Icing

    I love pudding icing!  The key is sifting the pudding and mixing until the mixture is no longer gritty.  I will never forget the first time I tried to make pudding whipped icing.  I didn’t sift or mix long enough, wasn’t a pretty sight.   The other suggestion when making this icing, is to use cold milk if the icing gets to thick.

    Let’s Build a Peanut Butter Layer Cake!

    Time to find that pretty cake plate or pedestal to display your beautiful cake!

    Start with a layer of cake, then add a layer of filling.  Sprinkle some of the white chocolate pieces on top of the filling.   Keep on going until you have used all the layers.  The top will not have filling or pieces.   Chill the cake for 15 to 20 minutes before icing.

    The Icing on the Cake

    On a very chilled cake, cover the top and sides with the White Chocolate Whipped Icing.   I like to add a top and bottom border to this cake but it’s up to you on how you would like to decorate.  To finish off, sprinkle white chocolate pieces on top of the cake.

    Add peanut butter and mix well. Make sure that the peanut butter is well incorporated.


    Divide batter between the 2 8 x 2” pans.
