Preheat oven to 350 degrees F.
Spray a 9x5-inch loaf pan with nonstick cooking spray; set aside.
In a mixing bowl or stand mixer, combine Greek yogurt, protein powder and self rising flour until a thick dough forms (continue to knead or add more flour if it is too sticky to handle).
Divide dough in half and roll dough into two long strips. Use kitchen shears and cut off dough into 1-inch pieces.
Sprinkle chopped pecans in the bottom of the loaf pan. Top with half the dough.
Sprinkle half the dry pudding mix over the dough.
Combine melted I Can’t Believe It’s Not Butter, Swerve and protein powder together until smooth and pour half the mixture on top. Repeat layers.
Bake for 30 minutes, or until golden brown on top.
Remove from the oven, use a knife to cut around the edges of the pan and carefully invert the loaf pan onto a plate to serve.
