Method
- Crust: Mix crumbs, sugar, and melted butter; firmly press into a 9-inch pie pan; chill.
- Filling: Beat cream cheese, mascarpone, and powdered sugar until smooth. Gently incorporate liqueurs and espresso concentrate.
- Stabilize (optional): Melt bloomed gelatin over simmering water, then whisk into filling.
- Whip & Fold: Whip cold cream to soft peaks, fold into filling. Pour into crust and smooth top.
- Chill: Cover and refrigerate for 6 hours or overnight.
- Finish: Whip topping ingredients to stiff peaks; pipe or spread on pie. Garnish and serve chilled.
Notes
- Alcohol retention: Since this is a no-bake pie, the alcohol in Baileys and Kahlúa does not evaporate. According to USDA research, foods that are not heated retain up to 100% of their alcohol content. This pie should therefore be served only to adults or made with alcohol-free substitutions like coffee concentrate and vanilla extract for all-ages gatherings.
- Texture balance: Using both cream cheese and mascarpone creates a balance of structure and silkiness. Cream cheese alone can make the filling dense; mascarpone lightens it, giving a mousse-like mouthfeel.
- Optional stabilizer: Incorporating a small amount of gelatin or agar into the filling helps it slice cleanly, especially important in warmer environments or for make-ahead entertaining. This is common practice in mousse-based pies.
- Coffee depth: A spoonful of espresso concentrate or strong cold brew amplifies the mocha undertone of the Mudslide without thinning the filling, unlike brewed coffee.
- Serving tip: For clean slices, chill the pie overnight, then cut with a sharp knife dipped in hot water and wiped dry between cuts.
- Storage: Cover tightly and refrigerate for up to 3–4 days. For longer storage, wrap unfrosted pie well in plastic wrap and foil, then freeze for up to 1 month. Thaw overnight in the refrigerator before serving.
- Make-ahead: The crust and filling can be prepared a day ahead; garnish just before serving to maintain the whipped cream’s structure.
- Presentation ideas: Garnish with chocolate curls, cocoa nibs, or chocolate-covered espresso beans for a professional finish. Individual “mudslide dessert in a cup” portions (served in clear glasses or jars) make for an elegant party presentation.
