Step‑by‑Step Instructions for Dairy Free Key Lime Pie
Step 1: Prepare the Crust
Begin by preheating your oven to 350°F (175°C). In a mixing bowl, crumble your gluten-free graham crackers and combine them with melted vegan butter until evenly moistened. Press this mixture firmly into the bottom and up the sides of a 9-inch pie dish. Bake the crust for about 10 minutes, or until it’s lightly golden and fragrant, then remove it from the oven and allow it to cool slightly.
Step 2: Mix the Filling
In a large mixing bowl, whisk together the sweetened condensed coconut milk, egg yolks, fresh key lime juice, lime zest, and tapioca flour until the mixture is smooth and well combined. This creamy filling should be fully blended with no lumps. Take a moment to appreciate the delightful zesty aroma of the key lime juice—it’s the heart of your Dairy Free Key Lime Pie!
Step 3: Bake the Pie
Pour the prepared filling into your slightly cooled pre-baked crust, spreading it evenly with a spatula. Place the pie in the oven and bake at 325°F (160°C) for 18-20 minutes. Keep a close eye on it; the center should jiggle slightly when shaken, indicating a creamy consistency—this is what makes your key lime pie so irresistible.
Step 4: Cool the Pie
Once baking is complete, remove the pie from the oven and allow it to cool at room temperature for about 30 minutes. After it has cooled, transfer it to the refrigerator to chill and firm up for at least 4 hours, or ideally overnight. This chilling time allows the flavors to meld beautifully, making every bite a delight.
Step 5: Serve
Before serving your Dairy Free Key Lime Pie, dollop generous amounts of coconut whipped cream on top, adding an extra layer of creaminess. You can also sprinkle additional lime zest over the whipped cream for a pop of color and a burst of fresh flavor. Slice the pie and serve it chilled to enjoy a refreshing treat that everyone will adore!
