Heavenly Hash Cake Is Just as Good Wheat Free!


A couple of months ago, I posted my grandmother’s recipe for Heavenly Hash Cake.  I was missing her, and baking always makes me feel a little bit closer to her.  The only problem was my son could only have that version one day out of the week.  It’s heartbreaking to watch a little one, who LOVES chocolate, have to use such restraint because it means his mother, who also LOVES chocolate, must also use restraint.

My oldest always has great ideas and this particular day was no different.  My son was out of the house with his dad and I was trying to think of something to make for dessert.  I wanted Heavenly Hash, but didn’t want to deprive my son.  When asked to brainstorm other dessert ideas with me, she couldn’t let go of the idea of how good it would be to have a Heavenly Hash Cake again.  Her suggestion was to just make it without wheat.  She makes everything sound so easy. She’s like having your own personal cheerleader.  “Mommy, I know you can make this without wheat”, she says.  “Just try…You can figure out anything…You always come up with something great when you think you can’t…It would be a great surprise when they come home!”

I fell for it hook, line, and sinker as I always do.  Good thing because the wheat free version was just as good as the original!
