Recipe Yield: 9–12 bars

INGREDIENTS

1 box angel food cake mix (16 oz, dry mix only)
3/4 cup lemon curd
2 large eggs
Optional: powdered sugar, for dusting

INSTRUCTIONS

1. Preheat oven to 350°F (175°C):
Grease or line an 8×8 or 9×9-inch square baking pan with parchment paper, leaving a bit of overhang for easy lifting.

2. Mix the batter:
In a large bowl, stir together the dry angel food cake mix, lemon curd, and eggs until fully combined. The batter will be thick, fluffy, and a little glossy.

3. Pour and spread:
Spread the batter evenly into your prepared pan using a spatula. Smooth the top.

4. Bake until golden and set:
Bake for 25–30 minutes, or until the top is golden and a toothpick inserted in the center comes out clean. The bars should feel springy to the touch.

5. Cool, chill, and slice:
Let the bars cool completely in the pan. For the cleanest slices, refrigerate for 1 hour before cutting. Dust with powdered sugar before serving, if desired.

Helpful Tips to Perfect This Recipe

• Use Real Lemon Curd: Store-bought or homemade lemon curd with real lemon juice and zest gives these bars a vibrant, natural citrus flavor.
• Don’t Skip the Chill: A quick chill helps firm up the bars for slicing without affecting the soft, cakey texture.
• Dress Them Up: A dusting of powdered sugar or a drizzle of lemon glaze makes these bars look bakery-worthy with almost no effort.
