Substitutes In This Recipe

Can I Substitute Milk or Half and Half For the Heavy Cream?

No. You cannot substitute milk or half and half in place of the heavy cream. The high fat content is needed in the heavy cream to allow stiff peaks to form when it is whipped. Using milk or half and half would not give the same texture and outcome.

Can I Use Chocolate Chips in This Chocolate Mousse Cake Recipe?

Yes. Using chocolate chips where chocolate is called for works just fine for this recipe. Chocolate chips, white chocolate chips and semi-sweet chocolate chips are usually readily available in most grocery stores. Using chocolate chips does not alter the flavor or consistency and is a good solution.
