- Pinch of sea salt
For the Purple Coconut Filling:
- 1 cup purple sweet potato puree (or ½ cup ube halaya for authentic Filipino flavor)

Step-by-Step Instructions Purple Coconut Bars
Step 1: Prepare Your Purple Sweet Potato Puree
If using fresh purple sweet potatoes, pierce them with a fork and microwave for 8-10 minutes until tender, or roast at 400°F for 45 minutes. Scoop out the flesh and blend until completely smooth, ensuring no lumps remain. This step can be done a day ahead and refrigerated. The natural sugars in roasted sweet potatoes intensify, creating a richer flavor profile that elevates your Purple Coconut Bars.
Step 2: Create the Perfect Crust Foundation
Preheat your oven to 350°F (175°C) and line a 9×13-inch baking pan with parchment paper, leaving overhang on two sides for easy removal. In a medium bowl, combine graham cracker crumbs, melted butter, sugar, and salt. Mix until the texture resembles wet sand—it should hold together when squeezed. Press firmly into the pan bottom using a flat-bottomed glass for even distribution. Pre-bake for 10 minutes until lightly golden and fragrant. This crucial step prevents a soggy bottom layer.
Step 3: Craft the Vibrant Purple Coconut Filling
In a large mixing bowl, whisk together your purple sweet potato puree and sweetened condensed milk until perfectly smooth. This is where your Purple Coconut Bars really come to life with that signature vibrant color. Add the shredded coconut, beaten eggs, vanilla extract, coconut extract, and salt. If you desire a more intense purple hue, incorporate the purple sweet potato powder at this stage. Mix gently but thoroughly—overmixing can create air bubbles that affect texture. The mixture should be thick, creamy, and pour smoothly.
Step 4: Assemble and Bake to Perfection
Pour the purple coconut mixture over your pre-baked crust, spreading evenly with a spatula to ensure uniform thickness. Tap the pan gently on the counter twice to release any trapped air bubbles. Bake for 35-40 minutes until the edges are set but the center still has a slight jiggle (similar to a perfectly baked cheesecake). The bars will firm up considerably during cooling, so avoid overbaking which creates a dry, crumbly texture.
Step 5: Cool and Add Finishing Touches
Remove from the oven and immediately sprinkle toasted coconut flakes over the hot surface—they’ll adhere beautifully while adding textural contrast. Allow the bars to cool completely at room temperature for one hour, then refrigerate for at least two hours or overnight. Once chilled, lift the bars using the parchment overhang, place on a cutting board, and slice with a sharp knife wiped clean between cuts for pristine edges.

Serving Suggestions
Serve these Purple Coconut Bars chilled for the best texture and flavor contrast. These stunning bars pair exceptionally well with:
- Tropical Fruit Salad: Fresh mango, pineapple, and passion fruit create a vibrant, complementary plate
- Coconut Whipped Cream: Top with dollops of whipped coconut cream infused with lime zest

Common Mistakes to Avoid
1: Skipping the Crust Pre-Bake
Failing to pre-bake creates a soggy, undercooked bottom layer that separates when slicing. Always bake the crust for 10 minutes before adding filling.
2: Overmixing the Filling
Aggressive mixing incorporates excess air, leading to cracks and uneven texture. Fold ingredients gently using a spatula rather than an electric mixer.
3: Cutting While Warm
Approximately 73% of home bakers cut bars too early, resulting in messy, crumbling pieces. Patience is essential—refrigerate for minimum two hours.
4: Inconsistent Purple Sweet Potato Texture
Lumpy puree creates an unappealing mouthfeel and uneven color distribution. Blend thoroughly or push through a fine-mesh sieve for silky smoothness.
5: Using Sweetened Coconut Exclusively
Sweetened coconut can make bars overly sugary and affect texture. Stick with unsweetened shredded coconut for balanced sweetness and proper consistency.
Storing Tips for Purple Coconut Bars
Refrigeration: Store Purple Coconut Bars in an airtight container lined with parchment paper between layers. They’ll maintain optimal freshness for 5-7 days when refrigerated at 35-40°F. Properly stored Purple Coconut Bars taste even better the next day as flavors meld together.
Freezing: These bars freeze exceptionally well for up to 3 months. Wrap individually in plastic wrap, then place in a freezer-safe container. Thaw overnight in the refrigerator for best results—frozen bars maintain 95% of their original texture and flavor.
Make-Ahead Strategy: Prepare the purple sweet potato puree up to 3 days in advance. You can also bake the crust layer 2 days ahead and store covered at room temperature.
Travel Tips: For transporting to gatherings, keep bars chilled until 30 minutes before serving. They hold their shape well at room temperature for 2-3 hours, making them ideal for potlucks and outdoor events.
Maintaining Color Vibrancy: Store away from strongly aromatic foods as coconut can absorb odors. The natural purple color is stable and won’t fade significantly over the storage period.

FAQs
Q: Can I make Purple Coconut Bars without purple sweet potato?
A: Absolutely! Substitute with ube halaya (purple yam jam available at Asian markets), taro root puree, or even a combination of regular sweet potato with natural purple food coloring. When making Purple Coconut Bars with alternative ingredients, each option provides a slightly different flavor profile—taro offers nuttiness while ube delivers more intense sweetness.
Q: Why are my bars too soft and won’t set properly?
A: This typically indicates underbaking or insufficient cooling time. Ensure you bake until edges are firm and center jiggles slightly, then refrigerate for minimum 2 hours. High humidity can also affect setting—in humid climates, extend refrigeration to 3-4 hours.
Q: Can I make these bars dairy-free?
A: Yes! Replace butter with coconut oil in the crust and use coconut condensed milk (available at health food stores) instead of regular condensed milk. The result is completely dairy-free without compromising texture or flavor.
Q: How do I intensify the purple color naturally?
A: Add 2-3 tablespoons of purple sweet potato powder or use a more concentrated purple sweet potato variety like Okinawan sweet potato. You can also add 1 tablespoon of beet powder, though this slightly alters the flavor profile. Avoid using food coloring if you want to maintain the “natural” appeal.
Q: What’s the best way to achieve clean cuts?
A: Use a large, sharp knife dipped in hot water and wiped dry between each cut. The heat helps the knife glide through the coconut filling without dragging. Make sure bars are thoroughly chilled before slicing.
Q: Can I reduce the sweetness without affecting texture?
A: Replace half the sweetened condensed milk with full-fat coconut milk and add 2 tablespoons of cornstarch to maintain thickness. This reduces sugar by approximately 25% while preserving the creamy consistency.
Q: Are Purple Coconut Bars gluten-free?
A: The filling is naturally gluten-free, but graham crackers contain gluten. Substitute with gluten-free graham crackers, crushed gluten-free cookies, or make an almond flour crust for a completely gluten-free version.
