I made this for my mom’s birthday celebration this year. We spent a restful weekend at the coast. This cake added to the glory and fun of the retreat. I had so much fun frosting it with feminine embellishments. The Satin Buttercream is really special. It contains BUTTER and gelatin. Together~ a dance of texture occurs. If you like piping… you will really enjoy decorating this cake. If you don’t, well– this is one easy frosting to work with! How about the cake? MOIST! Parsnips are super cool. Their starchy-good sweetness make them an excellent choice for the spice-cake genre. The pecans function as flour, as do the teeny bit of chia seeds. The cake is soft but not crumbly and excellent the second day for breakfast. (wink, wink)

The frosting for this cake is amazing. It is glorious to pipe. If, however, you intend to frost the entire cake- top, sides etc, I recommend serving it room temperature. It firms up in the fridge and will not stick to the cake as well. I love it both ways. When I pipe, as you see in the photos, I personally like to chill it. The embellishments will also hold their shape beautifully if left at room temperature, though. You could always chill it and then pull it out 1 hour before serving for the best of both worlds.

  • 6 eggs preferably pasture-raised
  • 1.5 cups sprouted pecans, see method below in Recipe Notes*
  • 1 cup boiled and pureed parsnips
  • 3/4 cup avocado oil or butter melted
  • 1/2 cup raw honey
  • 2 T. chia seed meal, see method below in Recipe Notes**
  • 1/2 tsp. cinnamon
  • 1/2 tsp. baking soda, sifted
  • 1/4 tsp. sea salt
  1. Grease desired cake pan(s) and line the bottom(s), too, with parchment paper cut to size. Preheat the oven to 325 degrees Fahrenheit.
  2. Place chia seed meal, cinnamon, baking soda and sea salt in a small bowl. Stir well to mix. Set aside.
  3. Place remaining ingredients into blender: eggs, pecans, parsnip, fat of choice and honey. Blend for 30-50 seconds until the batter is smooth.
  4. With the motor on, add the dry ingredients. Process just long enough to incorporate them thoroughly, without over-mixing, about 5-8 seconds. Use a spatula to quickly fold in any dry ingredients by hand, if needed.
  5. Pour batter into prepared pan(s) and bake until toothpick inserted into center comes out clean or with dry crumbs adhering. Cool on rack before slicing or frosting.
  6. When cake is cool, slice horizontally through the middle, if desired, to frost the center as well as the top, for a layered cake.
Recipe Notes

* For every 4 cups of raw pecans, cover with room temperature, filtered water by two inches, and 2 tsp. sea salt.  Stir well to dissolve the salt.  Leave out overnight at room temperature to soak. Drain in a colander; and rinse well.  Place in your dehydrator or low temperature-capable oven at 95-145 degrees.  The process of completely drying out the nut can take as long as 48 hours, depending on your dehydrator. To check your nuts’ doneness, let one or all cool to room temperature.  Eat one.  It should be very dry and crispy, no softness or chewiness to the inside.  The nuts are now ready for use in this recipe. They will also have a good shelf life and leftovers may be stored in a sealed container in your pantry.

** To make chia seed meal, simply blend chia seeds in high-powered blender for 10 seconds. I blend 2 cups at a time for best results and store leftovers in the fridge.
