If you can't find key limes, you can use regular Persian limes, but the squares won't be quite as tart.

How to Make It

Step 1

Preheat oven to 350°.

Step 2

Place first 5 ingredients in a medium bowl; beat with a mixer at medium speed until creamy (about 2 minutes). Lightly spoon 1 cup flour into a dry measuring cup; level with a knife. Gradually add 1 cup flour to butter mixture, beating at low speed until mixture resembles coarse meal. Gently press two-thirds of mixture (about 1 1/3 cups) into bottom of an 8-inch square baking pan coated with cooking spray; set remaining 2/3 cup flour mixture aside. Bake at 350° for 12 minutes or until just beginning to brown.

Step 3

Combine 2/3 cup sugar, 3 tablespoons flour, baking powder, and 1/8 teaspoon salt in a medium bowl, stirring with a whisk. Add lime juice and eggs, stirring with a whisk until smooth. Pour mixture over crust. Bake at 350° for 12 minutes. Remove pan from oven (do not turn oven off); sprinkle remaining 2/3 cup flour mixture evenly over egg mixture. Bake an additional 8 to 10 minutes or until set. Remove from oven; cool in pan on a wire rack. Sprinkle evenly with powdered sugar.

I made these using Persian limes and they were a big hit!! Also tried them with Key Limes and everyone preferred the Persian limes version -- will definitely make them again -- others have asked for this recipe

This recipe is just "okay" - I was incredibly dissapointed in the overall texture and taste of these squares. I think I was expected a great key lime pie flavor - the cream of the texture, the tartness that tightens up your jaw and then the sweet ending that just melts in your mouth. Not even close on these bars and juicing all the tiny key limes just to get the 1/2 cup required makes me sad for the wasted effort and ingredients to have the flavor fall so flat. The crust and the streusel just aren't up to snuff, and perhaps I'm expecting to much from a "light" dessert here. I won't be making these again, and if I take the time to juice another 1/2 of key limes, I'll probably just make myself the full fat pie version...

I love this recipe. My daughter is a big key lime fan and we enjoy these bars. Yes they are tart, but isn't that what lime is all about? Simple to prepare and a wonderful addition to a summertime meal. Try them out!

VERY sweet. I used high quality key limes, reduced the sugar to 1/2 cup in the egg mixture, and did not use powdered sugar on top. The lime taste was OK but I will not make these again.

I ended up not serving it at my shower since the squares were a big mess (streusel topping and powdered sugar everywhere) and didn't look very good. They tasted good to me (I tried them after everyone left), but were a lot of work. I used 3 regular limes and supplemented with bottled lime juice. I don't think the crumbly topping added much value or taste. Probably won't make them again.
