A fun twist on a classic recipe - this blood orange poppy seed cake has a bright citrus flavor!
Preheat oven to 375 degrees. Lightly grease a 9-inch round cake pan.
Whisk the spelt flour, sugar, baking powder, salt, orange zest, and poppy seeds together in a large bowl.
Store leftover cake in the refrigerator in an airtight container. It should stay fresh for up to 4 days.
If you can't have poppy seeds, go ahead and leave them out.
I have not made this recipe with gluten free flour, so I'm not sure how well it will work.
