Preheat oven to 350F. Line the bottom of a round 9-inch cake pan with parchment paper. Grease the pan and parchment with cooking spray.
In a large bowl, whisk together the honey, orange juice, oil, egg yolks, and orange zest.
In another bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
In a separate bowl, use an electric mixer to beat the egg whites until soft peaks form.
Add the dry ingredients slowly to the honey/egg mixture and mix until just combined, being careful to not over-mix. Gently fold in the egg whites.
Pour into the prepared pan and bake for 30-35 min or until golden brown and a cake tester comes out clean. Cool in pan for 10 minutes, then gently turn out the cake and continue cooling on a wire rack.
Serve with sliced almonds, powdered sugar, and additional drizzles of honey on each slice. You can also serve with whipped cream or vanilla ice cream.
