These homemade cheese cracker sandwiches feature crisp, buttery pastry squares filled with a savory chive and cream cheese spread. Making the cracker dough from scratch yields a beautifully flaky texture that pairs well with the rich, herby filling. They are an excellent choice for afternoon snacks, lunchboxes, or casual entertaining. You can prepare the crackers and filling ahead of time and assemble them just before serving to keep the pastry crisp.
