Step‑by‑Step Instructions for Low Carb Strawberry-Rhubarb Meringue Pie Bars
Step 1: Prepare the Crust
In a mixing bowl, combine the almond flour, coconut flour, and granulated erythritol. Melt the unsalted butter and pour it into the dry ingredients, mixing until crumbly. You’re aiming for a sandy texture, with no dry flour visible. Preheat your oven to 350°F (175°C) while you prepare the crust.
Step 2: Form and Bake Crust
Press the crust mixture firmly into the bottom of a greased baking dish. Use a flat-bottomed measuring cup or your hands for an even layer, smoothing the surface. Place the dish in the preheated oven and bake for about 12-15 minutes, or until the edges begin to turn golden brown. Keep an eye on it to avoid over-browning.
Step 3: Prepare Filling
While the crust bakes, wash and chop the strawberries and rhubarb into small pieces. In a separate bowl, toss the fruit together until well combined. Once the crust is baked and has cooled for a few minutes, pour the strawberry-rhubarb mixture evenly over the crust, spreading it out smoothly to cover.
Step 4: Make Meringue
In a clean mixing bowl, beat the egg whites with cream of tartar using an electric mixer on medium speed until they form stiff peaks. This may take around 4-6 minutes, and you should see glossy, firm egg whites that hold their shape. Gently spread the meringue over the fruit filling, ensuring it covers all edges.
Step 5: Bake Again
Return the baking dish to the oven for about 10-12 minutes, or until the meringue is golden brown on top. Keep an eye on it, as meringue can brown quickly. The fluffy texture should contrast beautifully with the vibrant strawberry-rhubarb filling.
Step 6: Cool and Serve
Once out of the oven, allow the Low Carb Strawberry-Rhubarb Meringue Pie Bars to cool completely in the baking dish. This helps the layers set. After cooling, cut into bars using a sharp knife, and serve chilled or at room temperature with a dollop of whipped cream if desired.

Low Carb Strawberry-Rhubarb Meringue Pie Bars Recipe FAQs
What kind of strawberries should I use?

How should I store the pie bars?
For best results, keep your Low Carb Strawberry-Rhubarb Meringue Pie Bars in an airtight container in the refrigerator. They will stay fresh for up to 5 days. Avoid stacking them to maintain their texture and presentation, but if you do stack, place parchment paper between layers.

What if my meringue isn’t fluffy?
No worries! If your meringue doesn’t whip up to stiff peaks, it could be due to grease on your mixing tools. Be sure to use clean, dry bowls and beaters.
