Scale
- 1 3/4 cups (165 grams) cake flour
- 1/2 tsp baking powder
- 1/2 tsp baking soda
- 1/2 tsp salt
- 1/2 cup (115 grams) cool unsalted butter, cut into 8 pieces
- 1 1/4 cups (280 grams) granulated sugar
- 2 large eggs (room temperature)
- 2 1/2 tbsp (37 mL) key lime juice
- 1 tbsp key lime zest
- 1 drop green food coloring paste
- cup (177 mL) buttermilk (room temperature)
Icing
- 1 stick cool unsalted butter, cut into 8 pieces
- 8 oz (225g) cream cheese (room temperature), cut into 8 pieces
- 2 1/4 cups (5.3dl) powdered sugar, sifted
- 1 tbsp key lime zest
Instructions
- Preheat oven to 350*F/177*C. Line a muffin tin with 12 paper liners.
- Sift the cake flour, baking powder, baking soda, and salt three times, set aside.
- Using a mixer fitted with the paddle attachment, beat the butter on low until it’s softened a bit. Add the sugar and increase the speed to medium. Beat until fluffy, about four minutes. Add one egg at a time, beating well after each addition. Add the lime juice, zest, and food coloring and beat until mixed. (The mixture will look curdled.)
- Add the flour in three additions, alternating with the buttermilk, beginning and ending with the flour, scraping down the bowl as necessary. Mix on low until just combined. Fill each cupcake liner 2/3 full.
- Bake 20-25 minutes, until cupcakes spring back when touched. Cool completely and frost with cream cheese icing.
Icing
- Using a mixer fitted with the paddle attachment, beat the butter on low until it’s softened a bit. Increase speed to medium and add the cream cheese one piece at a time. Reduce speed to low and slowly add powdered sugar until combined. Beat in zest.
Notes
- For cool butter, remove from refrigerator 20-30 minutes prior to using.
