Bright, nutty muffins made with fresh orange juice and zest, almond flour, and a touch of vanilla and almond extract. Moist, fragrant, and lightly sweet—perfect for breakfast, brunch, or an easy snack with coffee.
Preheat oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or grease lightly.
In a large bowl, whisk together all-purpose flour, almond flour, baking powder, baking soda, and salt.
In a separate bowl, combine granulated sugar and orange zest. Rub the zest into the sugar with your fingertips until fragrant and slightly orange in color.
Whisk eggs, Greek yogurt, orange juice, olive oil, vanilla extract, and almond extract into the sugar mixture until smooth.
Fold the wet ingredients into the dry ingredients just until combined. Do not overmix; a few small lumps are okay.
Divide the batter evenly among the muffin cups, filling each about 3/4 full. Sprinkle tops with sliced almonds and coarse sugar if using.
Bake for 17–20 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
Cool in the pan for 5 minutes, then transfer muffins to a wire rack to cool completely.
