Preheat and Prep: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats to prevent sticking.
In a large bowl, whisk together the whole wheat flour, all-purpose flour, brown sugar, cinnamon, baking soda, and salt.
Ensure everything is evenly combined – this step is key for uniform flavor in your graham cracker recipe.
Add the cold, cubed butter to the dry mixture.
Use a pastry cutter, fork, or your fingers to work the butter in until the mixture resembles coarse crumbs, like pie dough.
In a small bowl, stir together the honey, milk, and vanilla extract.
Pour the wet mixture into the dry ingredients.
Stir with a wooden spoon until a dough forms – it should be slightly sticky but hold together. If too dry, add a teaspoon of milk; if too wet, add a sprinkle of flour.
Divide the dough in half and form into discs.
Wrap in plastic wrap and chill in the fridge for at least 30 minutes. This makes rolling easier and prevents spreading during baking.
On a lightly floured surface, roll one disc to about 1/8-inch thickness.
Use a pizza cutter or knife to cut into 2×3-inch rectangles (or fun shapes!).
Prick each cracker with a fork to mimic the classic dotted look and prevent puffing.
Transfer cut crackers to prepared baking sheets, spacing them 1 inch apart.
Bake for 12-15 minutes, rotating sheets halfway, until edges are golden brown.
Cool on the sheets for 5 minutes, then transfer to a wire rack to cool completely. They’ll crisp up as they cool!
Optional Topping: For extra sweetness, sprinkle with cinnamon sugar before baking.
