Introduction

These Rainbow Vanilla Cheesecake Bars are a vibrant and delightful twist on classic cheesecake. With colorful swirls and a creamy texture, they’re perfect for celebrations or any time you want a cheerful treat.

The image shows several square cheesecake bars with three distinct layers on a white marbled surface. The bottom layer is a crumbly brown crust, the middle layer is thick and creamy white cheesecake, and the top layer is a vibrant, colorful swirl of bright yellow, pink, orange, green, purple, and blue in a smooth, marbled pattern. The bars are cut neatly with sharp edges, and some crumbs are scattered around them. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

Cooking spray, for pan
9 graham crackers, crushed
6 tbsp. butter, melted
1/4 cup sugar
2 (8-oz.) blocks cream cheese, softened
1/4 cup sour cream
2/3 cup sugar
3 large eggs
1 tsp. pure vanilla extract
1 tsp. kosher salt
Neon food dye in 6 colors

Instructions

Step 1: Preheat the oven to 325°F and grease an 8″x8″ pan with cooking spray. In a bowl, combine crushed graham crackers, melted butter, and 1/4 cup sugar. Mix until well combined and press firmly into the bottom of the prepared pan to form the crust.
Step 2: In a large bowl, beat together the softened cream cheese, sour cream, and 2/3 cup sugar until smooth. Add the eggs, vanilla extract, and kosher salt, then beat until fully incorporated. Pour about half of this cheesecake mixture into the prepared crust and set aside.
Step 3: Divide the remaining cheesecake mixture evenly into six small bowls. Add a few drops of different neon food dyes to each bowl and stir until the color is evenly mixed. Spoon dollops of the colored mixtures over the plain cheesecake layer in the pan, alternating colors.
Step 4: Use a butter knife to gently swirl the colors together, creating a marbled effect. Place the cheesecake pan inside a larger roasting pan and pour boiling water into the roasting pan until it reaches halfway up the sides of the cheesecake pan.
Step 5: Bake for about 45 minutes, until the cheesecake is set but still slightly jiggly in the center. Turn off the oven and leave the door slightly open. Let the cheesecake cool in the oven for 1 hour.
Step 6: Remove the cheesecake from the water bath and refrigerate for at least 3 hours or overnight to fully set. Once chilled, slice into bars and serve.

Tips & Variations

Use a toothpick instead of a butter knife for more intricate swirling patterns.
Swap sour cream for Greek yogurt for a tangier flavor and added protein.
Try different food coloring shades to match holiday themes or party colors.
If you prefer a firmer crust, add a tablespoon of melted butter when mixing the crumbs.

Storage

Store the cheesecake bars in an airtight container in the refrigerator for up to 4 days. For longer storage, freeze the bars wrapped tightly in plastic wrap and foil for up to 1 month. Thaw in the refrigerator before serving. Enjoy chilled or at room temperature.
