Ingredients You’ll Need

For the Crust

• 2 cups all-purpose flour
• 1 teaspoon baking powder
• ½ cup butter (cold)
• 1 egg
• 2 tablespoons milk

For the Filling

• 5 cups rhubarb (fresh or frozen, sliced)
• 1 package strawberry gelatin mix
• 2 cups sugar

For the Topping

• 1 cup all-purpose flour
• ½ cup butter
• 1 cup sugar

How to Make Rhubarb Bars

Step 1: Prepare the Crust

Preheat your oven to 375°F (190°C) and grease a baking pan.
Mix flour and baking powder, then cut in butter until crumbly. Add egg and milk, mixing just until combined. Press the dough evenly into the bottom of the pan.

Step 2: Add the Filling

Spread sliced rhubarb over the crust. Sprinkle gelatin powder evenly on top—this adds flavor and helps create that signature sweet-tart balance.

Step 3: Make the Crumb Topping

Combine sugar and flour, then cut in butter until crumbly. Sprinkle this mixture over the rhubarb layer.

Step 4: Bake to Perfection

Bake for about 40–45 minutes, or until the top is golden brown and the filling is tender. Let cool completely before cutting into bars.

Tips for Perfect Rhubarb Bars

• Use fresh or frozen rhubarb – Both work well, but thaw frozen rhubarb first and drain excess liquid.
• Don’t overmix the crust – Keep it crumbly for a tender texture.
• Cool before slicing – This helps the bars hold their shape.
• Balance sweetness – Adjust sugar depending on how tart your rhubarb is.
