1/2 cup whole wheat flour
3/4 cup whole old-fashioned oats
1 tsp baking powder
1/2 tsp baking soda
1 pinch salt
1 Tbsp grapefruit zest
1 Tbsp poppy seeds
1/4 cup olive oil
3/4 cup whole milk Greek yogurt
1/4 cup raw, brown or coconut sugar
1 large egg
1/3 cup grapefruit juice
Preheat the oven to 410°F. Line a 12-muffin tin with silicone or paper cups.
Mix all dry ingredients in a large bowl.
Whisk together the wet ingredients in another bowl. Pour wet ingredients into the dry ingredients, stir just until combined (a few lumps are fine).
Divide the batter between the prepared muffin cups.
Reduce the oven temperature to 400°F and bake the muffins for 5 minutes. Reduce the temperature to 360°F and finish baking for 15-18 minutes, or, until a toothpick inserted comes out clean.
Cool the muffins in the pan for 5 minutes, then transfer them to a rack and cool completely.
