How to Make the Recipe

Let’s walk through the steps to make these Black-Raspberry Bliss Bars:

  1. Preheat your oven to 375 degrees F (190 degrees C). Grease a 9×13 inch pan and set it aside.
  2. In a medium bowl, stir together 1 cup sugar, 3 cups flour, and baking powder. Mix in salt and lemon zest. Use a fork or pastry cutter to blend in the butter and egg. The dough will be crumbly. Pat half of the dough into the prepared pan.
  3. In another bowl, stir together the sugar, cornstarch, and lemon juice. Gently mix in the black raspberries. Sprinkle the black raspberry mixture evenly over the crust. Crumble the remaining dough over the berry layer.
  4. Bake in the preheated oven for 45 minutes, or until the top is slightly brown. Cool completely before cutting into squares.

Pro Tips for Making the Recipe

Here are some tips to ensure your Black-Raspberry Bliss Bars turn out perfectly:

  • Use fresh black raspberries for the best flavor. If fresh raspberries aren’t available, you can use frozen raspberries, but thaw and pat them dry first.
  • Don’t overmix the dough, as it can make the crust tough.
  • Let the bars cool completely before cutting to ensure they hold their shape.
  • Consider using other types of raspberries or a mix of raspberries and blackberries for a different twist.

How to Serve

These Black-Raspberry Bliss Bars are versatile and can be served in various ways:

  • Serve warm with a scoop of vanilla ice cream for a delicious dessert.
  • Cut into smaller squares for a quick snack or lunchbox treat.
  • Pair with a cup of coffee or tea for a mid-afternoon pick-me-up.
  • Bring to a potluck or picnic for a crowd-pleasing dessert.

Make Ahead and Storage

These bars are perfect for making ahead and storing:

  • Store in an airtight container at room temperature for up to 3 days.
  • Refrigerate for up to 5 days for freshness.
  • Freeze for up to 2 months. Thaw at room temperature or reheat in the microwave.
