Tips
Chill your mixer bowl in the freezer for 10-15 minutes before whipping cream to help achieve better peaks and prevent overwhipping.
Reserve extra graham crackers from the box in case you need to cut pieces to fill gaps in your layers for complete coverage.
The coffee fudge mixture will look like chocolate milk when hot but will thicken to proper fudge consistency once cooled in the refrigerator.
Good to Know
Refrigerate covered for up to 3 days. The flavors continue to meld and improve after the first day.
Can be assembled completely up to 2 days in advance. Keep tightly wrapped in refrigerator until ready to serve.
Slice with a sharp knife wiped clean between cuts. Serve chilled directly from refrigerator for best texture and flavor.
Common Mistakes
Don't skip chilling the mixer bowl as warm equipment can prevent proper whipping of the cream.
Allow the coffee fudge mixture to cool completely before assembly or it will melt the whipped cream layers.
Line the pan thoroughly with plastic wrap or the cake will be difficult to remove intact.
