Step-by-Step Patisserie Baking Timeline

1. Step 1
   Prep the patisserie pan: Preheat your oven to 350°F (175°C) with the rack centered, and line your anodized aluminum pan with parchment for Pumpkin Cinnamon Streusel Muffins.
2. Step 2
   Whisk the dry aerated base: Sift the cake flour, flavor base, sugars, baking powder, baking soda, and fine sea salt into a large bowl, whisking for 30 seconds to distribute the leaveners evenly.
3. Step 3
   Emulsify wet ingredients & bloom: Whisk the room-temperature eggs, buttermilk, melted butter, and vanilla together, fold into the dry ingredients just until combined, then stream in the warm liquid for a glossy patisserie batter.
4. Step 4
   Bake to a springy dome: Bake Pumpkin Cinnamon Streusel Muffins at 350°F (175°C) until the centers spring back lightly to the touch and a wooden skewer comes out with a few moist crumbs.
5. Step 5
   Whip & pipe the signature frosting: Beat the softened European butter for 4 minutes until pale and aerated, slowly incorporate the sifted confectioners' sugar and signature flavorings, and swirl generously over the cooled bake.
