Preheat oven to 350 F.
In a large bowl, cream 3/4 cup of butter with 3/4 cup of brown sugar until light and fluffy using a hand or a stand mixer.
Add 1 and 1/2 cups of rolled oats, flour, vanilla, baking powder, and salt to the mixture. Continue to blend until fully combined. The mixture should resemble crumbs.
Move the mixture into a 9x9-inch baking pan, and tightly press it in to create an even layer on the bottom. Spread cranberry sauce on top to create the topmost layer.
In a saucepan, melt 3 tablespoons of butter over medium heat. Then remove from heat once melted and stir in the remaining 1/4 cup brown sugar, 1/2 cup oats, pecans, and cinnamon. Stir until fully integrated. Sprinkle and equally distribute the topping on top of the layer of cranberry sauce.
Bake for 30 to 35 minutes until the mixture becomes lightly browned. Place on a wire rack to cool down and rest then cut into 9 squares.
Enjoy!
