Preheat your oven to 350°
Butter an 8”x4” loaf pan and line with a parchment paper sling leaving 2-3 inches overhanging on both sides
Thoroughly clean your oranges and slice off any thick ends (I like to add most of the peel, but will trim off the ends)
Place the prepped oranges into a blender and blend until a smooth pulp forms
In a large bowl, vigorously whisk 4 large eggs with 220 grams of granulated sugar and a teaspoon of pure vanilla extract until pale yellow and creamy
Add the orange pulp and mix until combined
Add 240 grams of almond flour and a teaspoon of baking powder and mix until just combined
Transfer the batter into the prepped loaf pan and bake in a 350 degree oven for about an hour or until a toothpick will come out of the center of the cake clean and it feels set to a light touch (if the cake wobbles in the middle, looks wet or feels soft in the center, let it bake longer or it will collapse as it cools)
