Separate dates and put in a medium pot with all other filling ingredients. Bring to a boil, then reduce to a simmer while making cookies, stirring frequently.
In a medium bowl or stand mixer, combine butter, oil and both types of sugar. Beat until creamy then add egg and vanilla and mix until well combined.
In another bowl, combine quick oats, oat bran, whole wheat flour, all-purpose flour, baking powder and baking soda.
Add the dry ingredients to the wet. Use a cookie scoop or your hands to form balls about 2 Tbsp each. Flatten between palms and place on parchment-lined baking sheet. Bake at 375 °F (190 °C) for approximately 10-12 min until cookies have spread out and are golden brow.
Let cool on wire rack, then top a cookie with 3 Tbsp (45 mL) date filling. Top with second cookie and wrap in plastic or store in a single layer in an airtight container. They freeze well!
