These Best Pumpkin Coffee Cake Muffins taste so close to the original Starbucks version that my sister accused me of just buying them and pretending I made them. After twelve batches, I finally cracked the code for perfectly moist muffins with a buttery streusel layer baked in the middle and piled high on top.
Room temperature ingredients are crucial. Cold eggs or buttermilk can seize the melted butter. Let streusel cool before layering to prevent sinking. Store muffins with paper towels in an airtight container to keep streusel crispy. For best results, use fresh baking powder.
