Ingredients
 
 

For the crumb

For the cinnamon roll filling

For the glaze

  • 1 cup powdered sugar sifted
  • 1 tbsp sour cream room temperature
  • 1 tbsp heavy cream room temperature
  • 1/4 tsp vanilla
  • Pinch of salt
  • 1-2 tsps milk optional

Instructions
 

  • Preheat the oven to 350℉/180℃. Line a 9x9 pan with parchment paper and set aside.

For the crumb

  • Add the flour, softened butter, white sugar, baking powder, and salt into a bowl. Mix with your hands or a fork until a crumb forms. Set 1 1/2 cups aside for the topping.
    3 cups all-purpose flour, 1 cup unsalted butter, 1/4 cup white sugar*, 3/4 tsps baking powder, 1/4 tsp salt
  • With the remaining crumb, transfer it into the prepared pan and spread evenly. Press down gently but not to firmly, and slightly up the side of the pan as well.
  • Bake the base for 20 minutes.

For the filling

  • Melt the butter and pour it into a bowl. Then add the brown sugar and cinnamon in and mix until combined.
    6 tbsp unsalted butter, 3/4 cups dark brown sugar, 2 tsp cinnamon
  • Once the base is baked, remove from the oven and increase the oven temperature to 375℉/190℃.
  • Gently spread the filling on top, making sure not to disturb the base layer and leaving about 1cm around the edges. Take the remaining crumb and sprinkle it on top.
  • Place the bars back in, and bake for 40-50 minutes, or until the top has become a light golden brown color.

For the glaze

  • In a pot over medium heat, add the heavy cream and sour cream and whisk together until combined. Remove from heat, then add in vanilla, salt, and powdered sugar. Whisk to combine until smooth. If the glaze is to thick for your liking, add 1 tsp of milk and mix.
    1 cup powdered sugar, 1 tbsp sour cream, 1 tbsp heavy cream, 1/4 tsp vanilla, Pinch of salt, 1-2 tsps milk
  • Drizzle the cooled bars, allow to set, slice, and enjoy!

Notes

White sugar*: If you prefer a sweeter crumb, feel free to add another 1/4 cup (50g) of white sugar, making the total 1/2 cup (100g).
Brown sugar: I use dark brown sugar in this recipe as it carries more molasses and therefore adds more flavor. I highly recommend you also use dark brown sugar, but if you don't have any on hand, light brown will also work. White sugar will not work.
Heavy cream: I used 35% heavy whipping cream, but 18% also works. I believe 10% would be to thin, but if you enjoy a thinner drizzle, you may try it.
