These whole wheat apple muffins have a tender, spiced muffin base dotted with chunks of apple and topped with a sweet, buttery streusel. They are mouth wateringly delicious!
Preheat the oven to 400°F with the rack in the center position. Line 6 standard size muffin cups with paper liners or grease well with butter.
In a small bowl, whisk together 1 cup soft white wheat flour, 1 teaspoon baking powder, ¼ teaspoon sea salt, 2 teaspoons ground cinnamon, ¼ teaspoon ground allspice, and ¼ teaspoon ground nutmeg.
In a medium bowl, using an electric mixer, beat ¼ cup unsalted butter and ⅓ cup packed brown sugar together until combined and fluffy. Add 1 large egg and beat on high speed until lightened in color, about 30-60 seconds. Add ¼ cup plain yogurt and 1 teaspoon vanilla extract, mix on low just until combined.
Add the dry ingredients and mix on low speed until combined, increase the speed to high and beat for about 30 seconds.
Fold in ⅔ cup peeled apple cunks.
Divide the batter evenly between the prepared muffin cups.
Combine all the streusel ingredients: 3 tablespoons soft white wheat flour, 2 tablespoons granulated cane sugar, 1 tablespoon melted butter and 1 pinch sea salt. Spoon evenly over the muffin batter, and press it lightly into the batter.
Bake for 14-16 minutes or until a toothpick inserted into the center of a muffin comes out with a few moist crumbs.
Let cool in the pan for 5-10 minutes before transferring to a cooling rack.
Notes
You can use brown sugar in the streusel topping, it will just be the same color as the muffins, taste is 10/10 though :)You can use hard white wheat flour or spelt flour in this recipe.
