Preheat the oven to 400°F. Line a muffin tin with tall paper liners.
In a medium bowl, whisk together dry ingredients, including the sugar and pudding mix.
In a separate bowl, mix wet ingredients and zest.
Gradually add the wet ingredients to the dry ingredients and fold until combined. Do not over-mix the batter.
Fill each tulip liner 3/4 of the way full.
In another bowl, combine all of the crumble topping ingredients.
Mix until the ingredients form a crumble.
Add 1/8 to 1/4 cup over each muffin batter.
Bake in a preheated 400-degree oven for 20 minutes. Check the muffins after 15 to make sure they need more time.

Notes
Always remember not to overmix—stirring just until the ingredients are combined is my secret to preserving that perfect muffin texture.
Do not overmix: The batter should be folded until just combined.
Baking time varies: Adjust the time based on the size of the muffins.
Experimental flavors: Mix in fruits or chocolates for variety.
Texture matters: A light touch ensures a tender muffin.
This recipe is for nine large, bakery-style muffins. If you are using a smaller muffin liner, you will need to adjust the baking time. This recipe will also make 18 muffins if they are smaller.
