Heat your oven to 360°F (180°C) to get it ready for baking.
In a large bowl, whisk together the egg, honey, Greek yogurt, vanilla extract, and olive oil until smooth.
Add the flour, protein powder, baking powder, and baking soda to the wet mix and stir lightly just to combine, avoiding overmixing.
Carefully fold in the blueberries, making sure not to break them apart.
Divide the batter evenly into a lined muffin tin to fill 12 cups.
Bake in the center of the oven for 15-20 minutes, or until a toothpick comes out clean from the muffins.
Let the muffins cool in the pan briefly before moving them to a rack or plate to finish cooling and to keep their shape.
