Whole Wheat Huckleberry Crumb Muffins

Ingredients

• cooking spray
• 0.75 cup milk
• 0.5 cup white sugar
• 0.25 cup butter, melted
• 1 egg
• 0.25 teaspoon vanilla extract
• 1.25 cups all-purpose flour
• 0.75 cup whole wheat flour, divided
• 1 tablespoon whole wheat flour
• 2.5 teaspoons baking powder
• 0.5 teaspoon salt
• 1 cup huckleberries
• 0.25 cup quick-cooking oats
• 0.25 cup light brown sugar, or more to taste
• 3 tablespoons cold butter
• 0.5 teaspoon ground cinnamon

Steps

1. Preheat oven to 350 degrees F (175 degrees C). Spray 1 muffin tin with cooking spray.
2. Combine milk, sugar, butter, egg, and vanilla extract in a bowl; mix until completely combined.
3. Whisk all-purpose flour, 1/2 cup plus 1 tablespoon whole wheat flour, baking powder, and salt in a separate bowl; fold into the milk mixture until batter is just combined. Fold in huckleberries to distribute them evenly.
4. Pour batter into the greased muffin tin.
5. Combine the remaining 1/4 cup whole wheat flour, oats, brown sugar, cold butter, and cinnamon in a bowl. Mix until crumbly and sprinkle over the muffins.
6. Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 15 minutes.
