This easy lime bar recipe is a dessert that will wow your guests. I baked these bars for a luncheon on a hot summer day. A gentleman made his way to the kitchen to compliment the cook who made them. —Holly Wilkins, Lake Elmore, Vermont
Preheat oven to 350°. In a large bowl, cream butter and confectioners' sugar until light and fluffy. Beat in lime zest. Combine flour and salt; gradually add to creamed mixture and mix well.
Press into a greased 13x9-in. baking dish. Bake just until edges are lightly browned, 13-15 minutes.
Meanwhile, in another large bowl, beat eggs and sugar. Combine flour and baking powder. Gradually add to egg mixture. Stir in lemon juice and zest; beat until frothy. Pour over hot crust.
Bake until light golden brown, 20-25 minutes. Cool on a wire rack. Dust with confectioners' sugar. Cut into squares. Store in the refrigerator.
Test Kitchen Tips
When zesting lime, remember this tip: The outermost part of a citrus fruit has the most desirable flavor. Be careful not to grate too far down into the peel. The lighter-colored inner part of the peel, the pith, tastes bitter.
To soften butter super-quick, partially unwrap the butter (use the wrapped half as a handle to keep your hand clean) and shred it using the largest holes of your box grater. The butter will reduce to a fluffy heap and soften faster. Shredded butter is ready to use in your recipe right away.
