Instructions

Preheat oven to 350ºF. Line a 12-cup muffin pan with paper liners.
Prepare chai spice mix and set aside.
In a bowl, whisk together cake flour, almond flour, baking powder, salt, and 1 Tbsp chai spice mix.
In a separate bowl, mix melted brown butter, sugars, eggs, and vanilla.
Stir in half the dry mixture, then espresso. Add remaining dry mix and stir until smooth.
Divide batter evenly into liners (¼ cup each).
Bake 18–22 minutes, until a toothpick comes out clean. Let cool completely.

To make buttercream:

Beat brown butter and powdered sugar until smooth.
Add chai spice mix, vanilla, and milk as needed.
Beat on high 4–5 minutes until fluffy.
Frost cooled cupcakes and dust with extra chai spice if desired.

Notes

Brown butter adds rich, nutty depth—don’t skip it.

Espresso can be replaced with strong coffee or milk.

For best buttercream texture, use softened brown butter.

Almond flour adds moisture and tenderness but can be swapped with all-purpose flour.

Store buttercream separately if making in advance.
