Heat your oven to 325 F.
In a medium bowl, combine the wet ingredients and mix well.
In a second bowl, stir together the flour, baking powder and oatmeal.
Combine the wet and dry mixtures until a tacky dough forms. If you use a stand mixer, you may have to switch to the dough hook.
Roll out the dough on a lightly floured surface to ¼-inch thickness and cut out shapes with a cookie cutter.
Place the biscuits on a nonstick baking sheet* and bake for 15 minutes.
Flip the biscuits over and bake for another 10 minutes.
*If you don’t have a nonstick baking sheet, you can line your baking sheet with parchment paper or a silicone baking mat.
