Key Lime Pie Madeleines are a delicious mini dessert recipe! With French and Italian roots, these mini cakes, also thought of as cookies, are soft and full of lime citrus flavor plus graham cracker flavor just like the pie! A delicious holiday dessert recipe, for spring, and summer.
Measure the flour and cornstarch by first putting the cornstarch into the measuring cup, and then filling the rest of the way with the flour. This will give you the 2 Tablespoons cornstarch and 1 cup minus 2 Tablespoons flour.
Whisk the flour, cornstarch, 1/4 cup graham cracker crumbs, and salt together in a small bowl. Set aside.
In a stand mixer or with a hand mixer in a large bowl, whisk the eggs and egg yolk together at high speed until frothy, about 3 minutes.
Add the sugar, vanilla, and lime zest and continue whisking until the mixture is thick, about 3 minutes more.
Using a spoon or spatula, fold in the flour mixture until just combined.
Add the cooled melted butter and fold until just incorporated.
Refrigerate the batter for 30 minutes. (Optional, but will help give you the classic bump)
Spray your madeleine pan lightly with a nonstick spray.Fill each mold with the batter, about to the top of the mold.
Bake 5 minutes and rotate the pan.
Bake an additional 3-5 minutes and remove when the edges are a very slight golden brown and the centers are set and no longer liquid.
Let the madeleines sit in the pan 5-10 minutes before removing and setting on a cooling rack to finish cooling.
Let the pan cool so it is no longer hot. Refill with the remaining batter and repeat cooking time.(The batter is much thicker the second time around but it will flatten out very quickly in the oven).
Decorating
If choosing to decorate, let the madeleines cool completely first.
Dunk each madeleine into lime glaze at an angle, about 1/3 to 1/2 way up. Let excess glaze drip off.
Immediately dunk into a small bowl of graham cracker crumbs.
Let dry on parchment paper.
Madeleines can be stored in an air tight container for up to 3 days but are best when eaten fresh.
