Preheat the oven to 350º. Grab your Circulon mini loaf pan and set it aside.
In a mixing bowl, cream butter and sugar until light and fluffy. Add eggs, one at a time, beating until combined. Beat in lime juice and zest.
Combine flour, baking powder, and salt. With the mixer on low, add the flour mixture alternately with the milk.
Pour into your mini loaf pans. Bake at 350º for 25 minutes or until a toothpick inserted near the center comes out clean.
Cool for 10 minutes on a baking rack. Remove cakes and cool completely.
Combine glaze ingredients. If the glaze is too thick add more lime juice. If it's too thin, add a little more powdered sugar and whisk until smooth.
Drizzle cooled loaf with glaze or serve the glaze on the side. Top with a key lime slice for added decoration.
