Heat oven to 350°F. Line a 9-inch square pan with parchment, leaving overhang.
Stir together the topping sugar and cinnamon; set aside.
Cream softened butter with brown sugar and granulated sugar until light and fluffy.
Beat in the beaten egg and vanilla until smooth.
Whisk flour, baking powder, salt, and cinnamon in a separate bowl.
Blend dry ingredients into the butter mixture just until a soft dough forms.
Press about two-thirds of the dough evenly into the pan. Chill the rest for topping.
Bake the base for 10 minutes until slightly set.
Melt caramels with cream and 1 tbsp butter over low heat, stirring until smooth. Stir in cinnamon and sea salt.
Pour the warm caramel over the hot crust and spread gently to the edges.
Crumble remaining dough over caramel. Sprinkle with pecans and the cinnamon-sugar topping.
Bake 15–18 minutes, until golden on top and the caramel bubbles at the edges.
Cool completely in the pan. Lift out and cut into 16 bars.
Notes
Try drizzling the cooled bars with melted dark chocolate, or swap pecans for walnuts. For a softer bite, warm a bar for 8–10 seconds before serving.
