Creating Easy Cranberry Orange Muffins with Streusel Topping is simple if you follow these steps:

1. Preheat the Oven: Set your oven to 375°F (190°C) to preheat.

2. Prepare Muffin Tin: Grease a muffin tin or line it with paper liners for easy removal.

3. Mix Dry Ingredients: In a large bowl, whisk together flour, granulated sugar, baking soda, baking powder, and salt.

4. Combine Wet Ingredients: In another bowl, mix the orange juice, egg, vegetable oil, vanilla extract, and orange zest.

5. Combine Mixtures: Pour the wet ingredients into the dry ingredients, folding gently until just combined. Do not overmix. Gently fold in the cranberries.

6. Prepare Streusel Topping: In a small bowl, combine brown sugar, flour, oats, softened butter, and cinnamon until crumbs form.

7. Fill Muffin Cups: Spoon the batter into muffin cups, filling them about ¾ full. Sprinkle the streusel topping generously over each muffin.

8. Bake: Place the muffin tin in the oven and bake for 25-30 minutes or until a toothpick inserted into the center comes out clean.

9. Cool: Once baked, remove the muffins from the oven and let them cool for about 10 minutes in the pan before transferring them to a wire rack.

These steps will guarantee a batch of scrumptious muffins that everyone will love!
