Aura Indigo Galaxy Cheesecake Bars (Print Version)

Vibrant cheesecake bars with a blue-purple galaxy swirl, buttery crust, and subtle floral notes.

# Ingredients:

→ Crust

01 - 200 g digestive biscuits or graham crackers, finely crushed
02 - 70 g unsalted butter, melted
03 - 2 tablespoons granulated sugar
04 - Pinch of salt

→ Cheesecake Filling

05 - 450 g cream cheese, softened
06 - 120 g sour cream
07 - 120 g granulated sugar
08 - 2 large eggs
09 - 2 teaspoons pure vanilla extract
10 - 1 tablespoon lemon juice
11 - 1 tablespoon cornstarch

→ Color & Galaxy Swirl

12 - 2 teaspoons butterfly pea flower powder or 8–10 dried butterfly pea flowers, steeped in 3 tablespoons hot water and strained
13 - 1/4 teaspoon purple gel food coloring (optional)
14 - 1–2 tablespoons whole milk (if needed for swirling)

# Steps:

01 - Preheat oven to 170°C. Line a 23x23 cm square baking pan with parchment paper, leaving an overhang for easy removal.
02 - Combine crushed biscuits, melted butter, granulated sugar, and a pinch of salt in a bowl. Press the mixture firmly and evenly into the base of the prepared pan. Bake for 10 minutes, then allow to cool slightly.
03 - In a large mixing bowl, beat cream cheese and sugar until smooth and creamy. Add eggs one at a time, mixing thoroughly after each addition. Blend in sour cream, vanilla extract, lemon juice, and cornstarch just until incorporated.
04 - Reserve approximately 120 ml (1/2 cup) of the cheesecake batter in a separate bowl. Mix in butterfly pea flower powder or the strained blue liquid. Add purple gel food coloring if desired for depth of color, and thin with whole milk as needed to achieve a swirling consistency.
05 - Spread the plain cheesecake batter evenly over the cooled crust, smoothing the surface.
06 - Drop spoonfuls of the tinted batter randomly over the surface. Use a skewer or knife to gently swirl and create an indigo galaxy pattern.
07 - Bake for 25–28 minutes, or until the center is just set and slightly wobbly.
08 - Allow to cool completely at room temperature, then transfer to the refrigerator and chill for at least 4 hours or preferably overnight.
09 - Using the parchment overhang, lift from the pan. Slice into 12 bars and serve chilled.

# Notes:

01 - For enhanced galaxy visual appeal, top cooled bars with edible silver or white star-shaped sprinkles.
02 - For a more decadent base, substitute chocolate cookies for a darker crust.
03 - Lemon zest may be added for additional brightness and aroma.
04 - Store cut bars refrigerated in an airtight container for up to 5 days.
