If you can’t be fussed with making coffee and dessert after a big holiday dinner, consider this twofer instead. The silky, sliceable, cool custard is rich and intense with two kinds of coffee, while the oatmeal crust is a tweedy-textured study in contrast. It’s prebaked to mitigate sogginess but doesn’t require pie weights. Mascarpone keeps the whipped cream firm and fluffy for a full 24 hours.
Don’t be tempted to skip the cold-brew concentrate. You don’t want regular cold brew, and definitely not brewed and cooled coffee from your coffee machine at home, no matter how fancy. The concentrate (highly recommend Grady’s Cold Brew Coffee Concentrate) is consistent every single time with exactly the right strength to stand up to the dairy and eggs in the filling.
