Follow these simple steps to create your delicious Cranberry Bliss Bars:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease and line an 8×8-inch baking pan with parchment paper.
2. Combine Dry Ingredients: In a bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, and ground cinnamon.
3. Mix Wet Ingredients: In a separate mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until smooth.
4. Add Eggs and Vanilla: Beat in the eggs, one at a time, followed by the vanilla extract until well combined.
5. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, stirring until just combined.
6. Fold in Cranberries and Chips: Gently fold in the chopped cranberries and white chocolate chips.
7. Bake: Pour the batter into the prepared baking pan and spread evenly. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
8. Cool: Allow the bars to cool in the pan for 15-20 minutes. Then transfer to a wire rack to cool completely.
9. Prepare Frosting: In a mixing bowl, combine the softened cream cheese and unsalted butter. Beat until creamy, then gradually add the powdered sugar. Mix in the vanilla extract until smooth.
10. Frost and Garnish: Once the bars have cooled, spread the cream cheese frosting evenly over the top. Sprinkle additional chopped cranberries for garnish.
