Tangy Florida Key lime curd set in buttery graham cracker crusts and crowned with airy whipped cream — these mini Key lime pies deliver every bit of the classic’s bright, refreshing punch in a single perfect bite.
They’re one of the 20 recipes inside our Mini Dessert Cookbook, and we’re sharing them in full so you can taste the standard before you buy the book. The hands-on time is short; most of the work is simply letting the curd chill until it slices clean.
Why this recipe works
Streaming sweetened condensed milk into pale-whisked yolks before adding the acid means the Key lime juice sets the curd naturally — whisk just until it thickens and turns glossy, about a minute, because overmixing loosens it again. Pulling the pies while the centers still jiggle, then chilling overnight, is what gives them that clean, sliceable set.

Instructions
- Build the graham crusts. Preheat oven to 350°F. Stir graham crumbs, melted butter, sugar, and salt until sandy. Press 3 tablespoons firmly into the base and sides of 6 buttered muffin cups or mini tart tins. Bake 7 minutes until set and fragrant.
- Whisk the Key lime curd. In a bowl, whisk egg yolks until pale, then stream in sweetened condensed milk. Add Key lime juice and whisk just until the filling thickens slightly and looks glossy, about 1 minute. Do not overmix or it will loosen.
- Bake and chill. Divide the filling evenly among the warm crusts. Return to the oven for 8 minutes until the edges are set but the centers still jiggle slightly. Cool to room temperature, then refrigerate at least 3 hours, preferably overnight.
- Top and serve. Whip heavy cream with sugar to soft peaks and pipe a generous rosette onto each chilled pie. Finish with a thin Key lime wheel and a shower of lime zest. Serve immediately for the brightest citrus aroma.
Fancy tip
Always use fresh Key lime juice; bottled juice tastes flat. If Key limes are scarce, substitute 2 parts Persian lime to 1 part lemon juice for balance.
