Ingredients
Before You Begin
Greek yogurt gives our pie a creamy texture; don’t substitute it.
Instructions
- Adjust oven rack to middle position and heat oven to 350 degrees. Process graham crackers and sugar in food processor to fine crumbs. Add butter and 2 tablespoons cream cheese and pulse until combined. Press crumbs into bottom and sides of 9-inch pie plate. Bake until lightly browned and set, 12 to 14 minutes. Cool completely.
- Combine 3 tablespoons lime juice and gelatin in small bowl and let sit until gelatin softens, about 5 minutes. Microwave until mixture is bubbling around edges and gelatin dissolves, about 30 seconds. Wipe out food processor and process condensed milk, yogurt, and remaining cream cheese until smooth, about 1 minute. With machine running, pour in gelatin mixture, remaining lime juice, zest, and vanilla and process until thoroughly combined.
- Scrape mixture into cooled pie shell and smooth top. Cover with plastic wrap and refrigerate until firm, at least 3 hours or up to 2 days. Serve.

Why This Recipe Works
We combined neufchatel cheese (a type of cream cheese with one-third less fat) with fat-free Greek yogurt for a creamy Reduced-Fat Icebox Key Lime Pie. The tanginess from the yogurt also enhanced the lime flavor, letting us cut back on the number of limes. Tasters found that fat-free sweetened condensed milk was almost indistinguishable from its full-fat counterpart. To further cut calories, we eliminated half the sugar in the crust before any of our tasters complained about a lack of sweetness. We reduced the amount of butter in the crust by mixing it with some of the neufchatel. This combination held the crust together without making it gummy.
