Yes, it can be made in advance and frozen. Once you have prepared the Matzo brittle, allow it to cool completely and break into pieces. Place them in an airtight container or resealable freezer bag. It can be stored in the freezer for up to 2-3 months. When you are ready to serve, simply let it come to room. However, it's important to note that the texture and crispiness of the Matzo may not be the same after freezing and thawing. The toffee layer may become slightly soft or sticky, but it should still taste delicious.
