Preheat your oven to 350°F (175°C).
In a mixing bowl, combine the shredded cheddar and cream cheese.
Add Parmesan, garlic powder, onion powder, salt, and pepper to the mix.
Spread the cheese mixture onto half of the Ritz crackers.
Top with remaining Ritz crackers to create sandwiches.
Place the assembled crackers on a baking sheet lined with parchment paper.
Bake in the preheated oven for about 10-15 minutes, or until the cheese is melted and bubbly.
Remove from the oven and let cool for a few minutes before serving.
If desired, sprinkle with chopped parsley before serving for a touch of freshness and color.
