Ingredients

Gather your simple ingredients to create these irresistible 3 Ingredient Rhubarb Squares:

• 14 ounces canned sweetened condensed milk
• 1 1/4 cups self-rising flour
• 2 cups fresh diced rhubarb
• 1 tablespoon confectioner’s sugar, for optional garnish

Notes & Substitutions

Sweetened condensed milk is crucial here, not evaporated milk, as it provides the sweetness and thick base for our squares. If you do not have self-rising flour, easily make your own by combining 1 1/4 cups all-purpose flour with 1 7/8 teaspoons baking powder and 1/4 teaspoon salt. For the best taste, choose fresh rhubarb stalks that are firm, crisp, and vibrant in color. You can find helpful tips on selecting quality rhubarb at The Produce Moms. Look for stalks that are mostly red; you can enhance their pink color by letting them sit in the batter for a few minutes before baking.

Equipment

You won’t need many special tools for this straightforward recipe. Just grab a few basics and get ready to bake!

• 9×9 inch baking pan
• Parchment paper
• Large mixing bowl
• Sturdy spatula or spoon

Instructions

Creating these easy 3 Ingredient Rhubarb Squares is incredibly simple. Follow these steps for perfect results every time.

First, preheat your oven to 350 degrees F (175 degrees C). Line a square 9×9 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!

Pro Tips & Troubleshooting

Do not be alarmed by the thick batter; it is essential for the structure of these rhubarb squares. Use a silicone spatula or the back of a spoon to press the batter firmly and evenly into the pan. Cooling time is crucial for these bars to set properly; if you cut them too soon, it might be crumbly. Always use fresh, firm rhubarb for the best flavor and texture. If your squares turn out crumbly, it might be due to not cooling them long enough or slight measurement discrepancies in the flour. Ensure precise measurements for optimal results.

Serving, Storage, & Variations

These delightful 3 Ingredient Rhubarb Squares are best served at room temperature, allowing their flavors and textures to shine. Store any leftovers in an airtight container at room temperature for up to 3 days. Avoid refrigerating, as it can alter the texture, making the squares too firm. Freezing is also not recommended, as the rhubarb can become watery upon thawing. For an extra layer of flavor, try adding a teaspoon of vanilla extract or a pinch of orange zest to the batter. You can also mix in a handful of fresh berries like strawberries or raspberries along with the rhubarb for a berry-rhubarb blend. For a different texture, sprinkle a simple streusel topping or a handful of rolled oats over the batter before baking.
