These bliss bars are a holiday favorite: rich, buttery, and bright with festive flavors. A soft, chewy blondie base is topped with a white chocolate cream cheese frosting and finished with chopped dried cranberries. They’re easy to make with all-purpose, white whole wheat, or a gluten-free measure-for-measure flour, and they’re the sort of dessert that vanishes quickly at parties.
Inspired by the well-known cranberry bliss bars, this version balances sweet and tart with a pillowy frosting and a tender blondie. They’re traditionally cut into triangles for a special presentation, but you can slice them any way you prefer.
Blondie base – The blondie batter used here is based on a classic recipe that relies on melted butter for the best texture and flavor. For these bliss bars the sugar was adjusted to 1 cup brown sugar plus 1/2 cup granulated sugar (instead of 2 cups brown sugar) and 1/2 teaspoon baking powder was added so the bars are set but still moist.
The batter is thick and holds add-ins well. White chocolate and chopped dried cranberries are stirred into the batter before baking to give pockets of sweet and tart throughout.
To finish the bars, a white chocolate cream cheese frosting is spread over the cooled blondies, then topped with more chopped dried cranberries and a little reserved frosting piped on top for decoration.
Ingredients
Overview of what you’ll need to make cranberry bliss bars:
- Butter – Unsalted butter, melted; it gives the blondies the best flavor and texture. Solid baking fats like butter are preferred over liquid oils.
- Brown sugar – Adds caramel notes and moisture.
- Granulated sugar – Provides structure and sweetness.
- Eggs – Bind the batter; avoid egg substitutes unless you are experienced with them in bar recipes.
- Flour – Use all-purpose, white whole wheat, or a gluten-free 1:1 measure-for-measure blend (see notes for adjustments).
- White chocolate – Chips or chopped white chocolate stirred into the batter and melted into the frosting.
- Dried cranberries – Chopped; they give a festive color and bright tartness.
- Cream cheese – The base of the frosting; use room temperature cream cheese for smooth frosting.
- Powdered sugar – For the frosting texture and sweetness.
- Milk – A few teaspoons to loosen the frosting if needed.
- Vanilla – Standard flavoring; almond or orange extract may be used in part for a citrus or nutty note.
- Optional – Orange zest, nuts, or warm spices like cinnamon for variations.
How to make them
Quick overview of the process—see the full instructions below for details.
The blondie batter will be thick; do not add extra liquid. Fold the white chocolate and chopped dried cranberries into the batter, spread it into a prepared 9″ x 13″ pan, and bake until the edges are lightly browned and the center is set. Cool completely before frosting.
After spreading the white chocolate cream cheese frosting over the cooled bars, scatter additional chopped cranberries on top and pipe reserved frosting as a finishing touch. Chill briefly before slicing for clean edges.
Pro tip: chill the bars before slicing and use a sharp, non-serrated knife to get neat cuts. Refrigerating makes the frosting firmer and helps prevent crumbling while cutting.
Why cut them into triangles?
Triangular slices give bliss bars an elegant, festive look that’s popular for holiday trays and parties. This shape is traditional for this style of bar, but feel free to cut them into squares or rectangles if you prefer.
Troubleshooting
- If the bars are dry, they were likely overmixed or overbaked. Aim for a center that is set but still moist.
- If the frosting is too loose, add more powdered sugar a tablespoon at a time until it thickens.
- If the bars crumble when slicing, make sure they are fully cooled and chilled briefly, and use a sharp knife.
Storage, make-ahead, and freezing
- Unfrosted bars: Store in an airtight container at room temperature up to 3 days, or refrigerate up to 5 days. Freeze layers wrapped with parchment between them for up to 3 months.
- Frosted bars: Refrigerate in an airtight container up to 5 days. To freeze, freeze frosted bars on a baking sheet until solid, then transfer to a sealed container. Thaw in the refrigerator before serving.
Variations
Ideas to change up the flavor:
- Use a chocolate brownie base instead of blondies for a richer bar that pairs beautifully with cranberries and white chocolate.
- Add citrus zest (orange, lemon, or lime) to the batter or frosting for a bright note.
- Replace part of the vanilla with almond or orange extract to complement the cranberries.
- Fold in chopped nuts like pecans or macadamias for crunch.
- Add warm spices such as cinnamon, nutmeg, or cardamom for a seasonal twist.
- Swap cranberries for dried cherries or apricots for a summer-friendly variation.
- Bake as mini bliss bars in a mini-muffin tin for bite-sized servings.
Gluten-free option
Use a 1:1 gluten-free baking flour blend that is designed to replace all-purpose flour directly. Two commonly used measure-for-measure blends produce good results; if you use a different brand, check package recommendations and be aware that weight adjustments may be needed for best texture.
Enjoy these bliss bars as an easy, festive dessert for holiday gatherings. If you try them, note any tweaks you make so you can repeat your best version.
