I found this great recipe here after doing a Google search for cheese crackers. Mack loves cheese crackers and these are so much better than Goldfish.
Whole Wheat Cheese Crackers
Adapted from High Five Recipes
1/2 cup unsalted butter, room temperature
1/2 teaspoon sea salt
2 cups shredded sharp cheddar cheese, room temperature
2 cups whole wheat flour (I used King Arthur White Whole Wheat)
1/2 teaspoon baking powder
2 tablespoons cold water
Preheat oven to 350F degrees.
In a large bowl, beat butter and salt until creamy. Add cheese and mix well. Gradually add flour, baking powder and water, mixing until dough begins to form a ball. Remove the dough from the bowl, divide in half and pat into two balls with your hands. Cover with plastic wrap.
Using one ball of dough at a time, roll the dough into 1/8 inch thickness between two pieces of parchment paper. Cut the rolled out dough in shapes with cutters or simply cut into 1 ½ inch squares. Place on parchment or silicon baking mat lined baking sheets.
Bake 15-17 minutes or until lightly browned. Allow to cool on pan for 5 minutes before removing.
