Creating Low-Carb Rhubarb Dream Bars is a simple process when you follow these clear steps:

1. Preheat your oven to 350°F (175°C) and grease a 9×9-inch baking dish.
2. Prepare the rhubarb: Chop the rhubarb into small pieces and set aside.
3. Mix the dry ingredients: In a large bowl, combine almond flour, erythritol, baking powder, coconut flour, and salt. Stir until well combined.
4. Combine the wet ingredients: In another bowl, whisk together the melted butter, eggs, and vanilla extract until smooth.
5. Combine mixtures: Gradually add the wet mixture to the dry ingredients, mixing until fully incorporated.
6. Fold in the rhubarb: Gently fold the chopped rhubarb into the batter, ensuring even distribution throughout.
7. Pour the batter into the greased baking dish, smoothing the top with a spatula.
8. Bake: Place the baking dish in the oven and bake for 30-35 minutes or until the edges turn golden brown and a toothpick inserted in the center comes out clean.
9. Cool: Once baked, remove the dish and let it cool for about 15 minutes before cutting into bars.
10. Serve: Cut into squares and enjoy your Low-Carb Rhubarb Dream Bars!
