  1. Preheat oven to 350 F. Line a 9 x 13-inch baking pan with non-stick foil or grease liberally with butter.

  2. Blend the flour, baking powder , and salt together in a small bowl. Set aside.

  3. In a large mixing bowl, cream butter and sugar together with a mixer, beating until blended. Add the eggs, 1-1/2 teaspoons Key lime zest, and 1 tablespoon Key lime juice.

  4. Into the butter-cream mixture in the large bowl, add 1/3 of the flour mixture, stirring by hand until combined. Add 1/3 of the buttermilk , stirring until combined. Continue alternating one-third of each until all is mixed well. Fold in white chocolate chips.

  5. Spread batter evenly in pan. Bake 35 to 40 minutes or until wooden pick inserted in center comes out clean. Spread Key Lime Glaze (instructions below) evenly over top of the warm cake and cool to room temperature. Just before serving, cut into serving pieces, and sift powdered sugar (optional) over the top of the pieces. Serve immediately.

  6. Key Lime Glaze:

  7. While the cake is baking, whisk powdered sugar and 1/8 cup Key lime juice together until combined and smooth. Use to glaze warm cake.

  8. Note: Key limes are about the size of a golf ball and yellow when ripe. The flavor is a bit sweeter and less acidic than Persian limes. If you cannot find fresh Key limes, bottled Key lime juice is available at most markets. As a last resort, standard Persian limes may be used.
