These homemade digestive biscuits have a thin, crisp texture and wholesome wholemeal flavor, with warm hints of cinnamon and vanilla. The dough comes together quickly and bakes in about 15 minutes, making them an easy everyday bake. Serve alongside a cup of tea or use them as a base for cheesecakes and tray bakes.
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper for easy cleaning.
In a large mixing bowl, combine the whole wheat flour, all-purpose flour, brown sugar, baking powder, cinnamon, and salt. Stir until evenly mixed.
Add cold, diced butter to the dry ingredients. Using your fingers or a pastry cutter, incorporate the butter until the mixture resembles coarse crumbs.
Mix milk and vanilla extract in a small bowl, then pour into the flour mixture. Stir until a dough forms.
Transfer the dough onto a lightly floured surface and roll it out to about 1/8-inch thickness.
Use a round cookie cutter to cut out biscuit shapes, re-rolling scraps as needed to utilize all the dough.
Place the biscuits on the prepared baking sheet and bake for 12-15 minutes, or until golden brown and crisp.
Allow the biscuits to cool on a wire rack before serving.

Notes
For a more rustic look, sprinkle a little raw sugar on top of the biscuits before baking.
For variations, consider adding a dash of nutmeg or substituting almond extract for a different flavor profile.
Keep the dough cool to prevent the butter from melting before baking; this helps maintain the crispness of the biscuits.
