This one, Marionberry-Hazelnut Cake is filled with his favorites, not marionberries or hazelnuts though. What is a marionberry? I used blueberries and planned to use almonds until I realized, I was out. I pulled out walnuts instead. I keep ground flours on hand with a celiac husband. Nut flours give flavor and are a partial substitute for the all-purpose flour. I use a gluten-free mixture and the nut flour. A Great Combo!
You can find the recipe here. My substitutions are as above, walnut flour, gluten free mix, blueberries. Otherwise, I was true to the recipe, another good recipe from this book.
