Ingredients
- Digestive biscuits or graham crackers: Choose the kind with a slightly sweet buttery flavor for a firm crust
- Unsalted butter: Look for high-fat European style for richer taste and holds the crust together
- Granulated sugar: Fine sugar ensures even blending in both crust and filling
- Salt: Just a pinch balances the sweetness in both layers
- Cream cheese: Use full-fat and bring to room temperature for ultimate creamy texture
- Sour cream: Adds tang and helps create a velvety cheesecake layer
- Eggs: Opt for large free-range eggs which blend more smoothly into batter
- Pure vanilla extract: Real vanilla rounds out floral and citrus flavors
- Lemon juice: Freshly squeezed brings brightness to the filling
- Cornstarch: Prevents the cheesecake from cracking and sets it firm
- Butterfly pea flower powder or dried flowers: Try to find high quality vibrant blue powder or well-dried flowers for the strongest color
- Purple gel food coloring: Optional but deepens the galaxy effect if desired
- Whole milk: Needed only to adjust swirl consistency if the colored batter is thick
Step-by-Step Instructions
- Prep the Pan:
- Line a nine inch square baking pan with parchment paper making sure there is enough overhang on the sides to lift the cheesecake bars out after chilling
- Make the Crust:
- Mix the crushed cookies melted butter sugar and salt in a bowl The texture should look like damp sand Press the crumbs into the bottom of the lined pan using your hands or the back of a measuring cup Aim for an even layer with no gaps Bake for about ten minutes No browning is needed just enough to set the crust
- Blend the Cheesecake Filling:
- With an electric mixer beat room temperature cream cheese and sugar on medium speed until silky and lump free Crack eggs into a small bowl then add them one at a time mixing until just absorbed after each Add sour cream vanilla lemon juice and cornstarch Stir only until blended to avoid overmixing which leads to cracks
- Prepare the Galaxy Swirl:
- Separate half a cup of cheesecake batter into a small bowl Stir in butterfly pea flower powder or the blue butterfly pea liquid Add purple food coloring if a deeper violet is desired If the batter looks too thick stir in up to two tablespoons milk for easy swirling
- Assemble Layers:
- Pour the plain cheesecake batter over the cooled crust Smooth the surface so it fills all corners Dollop blue and purple batter over the top in random spots
- Swirl the Galaxy Design:
- Using a thin skewer or knife gently swirl through the colored spots to create marbled indigo and purple patterns Avoid overmixing so the colors stay distinct
- Bake:
- Slide the pan into a preheated oven and bake for about twenty five to twenty eight minutes The center should jiggle slightly but not be liquid Resist overbaking since the bars firm up as they cool
- Cool and Chill:
- Remove from oven and let the pan cool on a rack to room temperature Cover and place in the refrigerator for at least four hours or overnight for best texture
- Serve:
- Carefully lift the bars from the pan using the parchment paper edges Slice into neat squares using a sharp knife wiped clean between cuts Serve chilled for prettiest swirls and clean edges
