These are easy enough to make with a box of mix, some oil and a couple eggs. I'll give you the full from scratch recipe I was going to use though. If only I hadn't run out of cocoa powder!
Blood Orange Brownies
from scratch version
2 cups sugar
3/4 cup Blood Orange Olive Oil
1 1/2 cup all purpose flour
1/2 tsp baking powder
1/2 tsp salt
1/2 cup unsweetened cocoa powder
Preheat the oven to 350 degrees. Grease an 9x13 inch pan.
Cream the eggs, sugar and olive oil together in a large bowl. Gently add the dry ingredients one at a time, stirring until fully combined.
Pour into your greased pan and bake for 20-25 minutes.
For the easy version, grab a box of brownie mix. Mix it all up according to the directions, except where it says to use vegetable oil. Use the olive oil instead. And you are done.
