This cake is for my Father-in-Law, Dennis Rettke.

He passed away last week.  Its was very sudden, very unexpected, and has left a huge gaping whole in our family.

Dennis and my Mother-in-Law Patty are quite beloved in their community and around the world.  Since Dennis retired from his job as a   Superintendent, they have traveled around the world.  (Living life without regret!) Thailand, Australia, Alaska, and England just to name a few.

But no matter where they go, Dennis would be quick to tell you his favorite place to go is one where he is surrounded by his eight grand-kids.

As people have come forward to share, story after story told reveals the great depths of Dennis’ generosity and kindness.  To call him beloved is a mighty understatement.

Everywhere they went, people were charmed and impacted by these two amazing people.

Patty has had guests and family in her home since the moment we heard the news.  She has been surrounded by love and prayers.  Being the exceptional entertainer she is, she has made meals and had desserts and provided nourishment for all.  Of course, many people have generously brought over meals and snacks.  We are so thankful for their kindness.

But this Thursday and Friday, when the viewing and funeral are going to take place, she will have more people in her home than can reasonably fit.  They are coming from far and near… traveling for many hours and even days.

And I wanted to help in any way I could.

Quite honestly, it has been very natural for me to turn to baking in my grief.  This past week I have made cakes and breads and much more.  But this cake, this cake is special.

It’s all for Dennis.

His favorite cake is, was, his wife’s specialty.  Chocolate Zucchini Cake.  But Dennis also loved all things blueberry.  So I decided to combine the two to make a cake that would encompass what he loved most.

Normally I try to adapt recipes and make them unique, but not this time.  I wanted to make the cake exactly as Patty does, exactly as Dennis loved to eat it.

After making this cake I realized how much friends had influenced me.  I recalled a beautiful Dark Chocolate and Raspberry Buttercream Cake that the talented Sweetapolita made.  I also remembered the fantastic Blueberry Buttercream from My Baking Addiction.  For the ganache, I recalled the best and easiest recipe I have ever come across, Ganache Three Ways by Savory Sweet Life.

I am thankful for these talented woman whose talent left such an impact on me that my subconscious mind recalled their creations long before conscious mind did.

I am sorry to have shared here the deep sadness and grief we are in the midst of.  I normally love to keep this blog joyful and light.  I am just hoping that among all the hundreds of family and friends gathering together to celebrate one phenomenal man, that we can focus on the love and light Dennis brought to this world.

That we can be together and soak up the stories, photos, and memories of someone who truly made the world a better place.

And that over his special cake, we can move towards the future holding his memory, his wisdom, and his unfailing love close to our hearts.

  • Tiffany | baking at tiffanys says:

    Thank you for sharing your grief. I can relate, having recently lost a friend myself, and wondering whether people wanted to read only about “happy” things. But life is precious (and so short!) and we should all be able to share in each other’s good times and bad times as well. Your cake is beautiful too, what a lovely tribute. God bless.

    I made this cake last night for a party this evening. It was a hit. And no one could tell there was zucchini in it. Of course I didn’t offer up the info, till everyone was done with cake eating. LOL Great cake, Easy to make, time consuming, but easy to follow instructions and quite a tasty cake. Thank you.
    I was gonna try to post pictures but I am not that tech savy.
