- First, preheat your oven to 350 degrees F (175 degrees C). Line a square 9x9 inch cake pan with parchment paper, allowing some overhang on the sides to easily lift the squares later. Set the prepared pan aside.
- In a large mixing bowl, combine the 14 ounces of sweetened condensed milk and 1 1/4 cups of self-rising flour. Use a sturdy spoon or spatula to stir these two ingredients together until they are just combined and no dry flour streaks remain. The batter will be quite thick.
- Next, add the 2 cups of fresh diced rhubarb into the bowl. Gently fold the rhubarb into the thick batter until it is evenly distributed. Do not overmix; just combine it. The batter will be extremely thick, which is perfectly normal, so do not be alarmed.
- Transfer the thick batter to your prepared, parchment-lined cake pan. Press the batter firmly and evenly into the pan, making sure to push it into all the corners. Use your spatula or the back of a spoon to get the top as flat and even as possible. This ensures even baking.
- Bake the squares in the preheated oven for 25 minutes. The top should be lightly golden and set when done.
- Remove the pan from the oven and place it on a wire rack. Allow the 3 Ingredient Rhubarb Squares to cool completely in the pan before attempting to remove them. This is a critical step for proper setting. Once fully cooled, use the parchment paper overhang to lift the entire slab out of the pan. Cut into 16 squares. If desired, dust the tops with confectioner's sugar before serving. Enjoy your homemade rhubarb treats!

Notes
Sweetened condensed milk is crucial; do not use evaporated milk. If you don't have self-rising flour, combine 1 1/4 cups all-purpose flour with 1 7/8 teaspoons baking powder and 1/4 teaspoon salt. For best results, use fresh, firm, vibrant rhubarb stalks. The batter will be thick, which is normal. Cooling completely is essential for proper setting. Store leftovers in an airtight container at room temperature for up to 3 days; refrigeration or freezing is not recommended. For variations, add vanilla extract, orange zest, fresh berries, or a streusel topping. Ensure precise measurements for optimal results.
