• 2 large eggs
• 1 tsp vanilla extract

For the Walnut Streusel Topping:

• ½ cup chopped walnuts
• ¼ cup all-purpose flour
• ¼ cup brown sugar
• 3 tbsp unsalted butter, cold and cubed

Instructions

1. Prepare the Oven
   Preheat oven to 375°F (190°C). Line a 12-cup muffin pan with paper liners.
2. Make the Streusel
   In a bowl, mix walnuts, flour, and brown sugar. Cut in cold butter with a fork or pastry cutter until crumbly. Set aside.
3. Mix the Dry Ingredients
   In a large bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt.
4. Mix the Wet Ingredients
   In another bowl, whisk together milk, oil, eggs, and vanilla extract until well combined.
5. Combine Wet and Dry
   Pour the wet mixture into the dry ingredients and stir until just combined — do not overmix.
6. Fill the Muffin Cups
   Divide the batter evenly among the muffin liners. Sprinkle streusel topping over each muffin.
7. Bake
   Bake for 18–22 minutes or until a toothpick inserted in the center comes out clean.
8. Cool and Serve
   Let muffins cool for 5 minutes in the pan, then transfer to a wire rack. Serve warm or at room temperature.
