These gluten-free apple streusel muffins are soft, moist, and packed with chunks of fresh apple and cinnamon. Made with almond flour and topped with a buttery streusel, they bake up with a golden, crisp topping and a tender crumb.
Preheat oven to 350°F (180°C). Line 12 muffin cups with liners or lightly grease them.
For the crumble:
Mix gluten-free all-purpose flour and sugars in a medium bowl. Add diced cold butter and mix with your fingertips until crumbs form. Place the crumble on a plate in the refrigerator.
For the muffins:
In a medium bowl, whisk together the gluten-free all-purpose flour, almond flour, baking powder, baking soda, salt, ground cinnamon, and ground nutmeg.
Beat the oil, brown sugar, granulated sugar, eggs, milk, and vanilla extract in a large bowl.
Add the sifted dry ingredients and the apples and mix until well incorporated. At this moment, you can also add chopped toasted walnuts. Don't overmix the batter; mix until combined.
Pour the mixture into the previously prepared pans. Fill the muffin cups ¾ full, dividing the mixture as evenly as possible. Sprinkle with the crumble.
Bake for 20-25 minutes until the tops are golden, and a toothpick inserted into the center comes out clean with no batter streaks.
Let cool before removing.
Notes
Store the muffins covered at room temperature or in the refrigerator for five days.
