Time is important and so precious. It seems to become more valuable when we lose someone that we love! Yesterday my mama left this world, 19 years ago. And then, it seems like only yesterday she was here on earth, one of the best persons I’ve ever known. Today is her birthday, and she would have been 82 years old. That is hard to fathom. So Happy Birthday Millie!

Mom showed me a lot, specifically the joy that comes from cooking for others. To serve them. To serve Him. To cook comfort foods, like a Sunday roast beef dinner, with veggies from the garden and hot buttered dinner rolls, and a delicious homemade dessert.

Mom’s garden was full of zucchini, so when I found this recipe in the pile that she left behind, I knew I needed to bake a cake for Mom today! (That’s mom’s handwriting from a card she sent me, on this plate, and then a little about her last letter to our family, here. Sweet keepsakes!)

Zucchini adds texture, and chocolate is always so satisfying!

I love to stir the cake batter by hand, because it’s nice and lumpy.

Another thing I learned from mom? You can make this cake ahead, and store it for 3-4 days! My mom was always baking cakes, freezing them, and frosting them right before the guests would arrive.

Making the most of our days is rewarding and enjoyable. How we choose to spend our time may not be the same for one person, as it is for another. I personally love to host people in our home. Others may prefer to meet for a meal out, or simply dessert and coffee.

I think my mom would approve of both, and of this cake for dessert today!

Happy Birthday, sweet mama Mildred!

  1. Blessings of peace & comfort as well as the joy of happy memories. Millie raised a wonderful daughter & this simple cake makes me think of how warm & gracious Millie must have been. Thank you for sharing a cherished recipe. PW

  2. I have a chocolate zuch recipe we love, too! SO moist!! We bought some rhubarb to make one of my Grandma’s recipes and inside the cookbook was a note she had written to my Granny saying she was cutting up rhubarb and how many calves had been born on the farm – my daughter got a kick out of that!

    One of your sons looks so much like your mom!

  3. Sandy, you are on my heart and in my prayers each time I read a post about your Mom.❤️Big hugs to you today.

  4. That looks so good. Definitely pinned it to make later. Hugs to you as you. I love to think of how much my mom would’ve enjoyed doing life with all of us were she still here. I LOVE making a recipe that was from her, and thinking about times she made it when we were younger.
