2 ½ cups (≈ 320 g) all-purpose flour
3 Tbsp (45 g) granulated sugar
1 tsp (5 g) salt
2 ¼ tsp (1 packet) instant yeast (or 2 ½ tsp active dry)
¾ cup (180 ml) buttermilk, room temperature (or milk + 1 Tbsp lemon juice)
3 Tbsp (42 g) softened butter
1 large egg, room temperature
½ cup (≈ 80 g) non-melting festive sprinkles
½ tsp vanilla extract (optional)
In a bowl, mix warm buttermilk, sugar, egg, butter, and vanilla. Add yeast, let sit ~5 minutes until foamy (if using active dry).
In another bowl, whisk flour + salt.
Combine wet + dry into a dough; knead until smooth and slightly tacky (~5–7 min).
Place dough in a greased bowl, cover, and let rise until doubled (45–60 min).
Deflate dough and turn onto a lightly floured surface. Gently fold in sprinkles (do not overmix). Shape into a loaf and place in a greased 9×5 pan.
Let rise again (~30 min) until dough rises just above the pan rim.
Preheat oven to 350 °F (176 °C). Bake 35–40 min until golden and internal temp ~190 °F (88 °C). Tent with foil if top browns too fast.
Cool in pan 10 min, then on wire rack at least 30 min before slicing.
Use non-melting jimmies sprinkles so color doesn’t bleed.
Let the loaf cool fully before slicing to avoid compressing the crumb.
For quicker rise, keep in a warm spot or slightly warmed oven (then turned off).
Slice and freeze leftover pieces for up to 3 months.
