Step-by-step overview

Making strawberry rhubarb bars is a breeze, and the process is quite enjoyable. You will begin by mixing the fruity filling while preparing a crumbly base and topping. Layering these components together leads to a lovely baked treat that’s worth every minute of your time. Let’s dive into how each part comes together.

What you’ll need

To prepare these delightful bars, gather the following ingredients:

  • 2 cups fresh strawberries, diced
  • 2 cups rhubarb, diced
  • 1 cup granulated sugar
  • 1/4 cup cornstarch
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour
  • 1 cup rolled oats
  • 1/2 cup brown sugar
  • 1/2 teaspoon salt
  • 1/2 cup unsalted butter, melted

Feel free to switch up the sugar with coconut sugar for a more caramel-like flavor or to use frozen fruits if fresh isn’t available. Just ensure to adjust the cooking time slightly as frozen fruits will release more moisture.

Directions to follow

  1. Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking dish.
  2. In a medium bowl, combine the diced strawberries, rhubarb, granulated sugar, cornstarch, and vanilla extract. Set this fruity mixture aside and let it marinate a bit.
  3. In another bowl, mix the flour, rolled oats, brown sugar, and salt. Pour in the melted butter and stir until you achieve a crumbly texture.
  4. Press half of this crumb mixture firmly into the bottom of your prepared baking dish to form the base.
  5. Next, pour that beautiful strawberry-rhubarb mixture over the crumb base. Spread it out evenly to ensure every bar has that perfect fruity filling.
  6. Crumble the remaining mixture on top of the fruit layer. A little unevenness in the topping creates a charming homemade feel—don’t worry about perfection.
  7. Bake in the preheated oven for 40-45 minutes or until the top is golden brown and your kitchen is filled with the enticing scent of baked fruit.
  8. Allow to cool completely before slicing into squares. Patience will reward you with cleaner cuts!

Best ways to enjoy it

These strawberry rhubarb bars shine on their own, but you could elevate the experience by serving them with a scoop of vanilla ice cream or a dollop of freshly whipped cream. For an extra touch, a sprinkle of sliced almonds or crushed pistachios adds a delightful crunch. Enjoy them warm or at room temperature for the best of both worlds!

How to store & freeze

To keep your strawberry rhubarb bars fresh, store them in an airtight container at room temperature for up to three days. If you have leftovers—or if you’re preparing ahead—these bars freeze beautifully! Just wrap the cooled squares tightly in plastic wrap and store them in a freezer-safe container. They’ll keep well for about three months.

When ready to enjoy them again, allow them to thaw in the fridge overnight, or simply leave them at room temperature for a while before digging in.

Helpful cooking tips

  • Use ripe strawberries for the best flavor. The sweetness of the berries balances the tartness of the rhubarb beautifully.
  • Make sure to evenly distribute the cornstarch with the fruit mixture; this will help thicken the filling without leaving gritty bits.
  • If your rhubarb is particularly tart, consider adjusting the sugar to suit your taste. There’s no shame in a little extra sweetness!

Creative twists

Feeling adventurous? Why not introduce some zest? A teaspoon of lemon or orange zest in the fruit mixture can brighten the flavors even more. For a more adventurous take, try adding a hint of cinnamon or nutmeg to the crumbly topping, giving the bars a cozy, spiced dimension.
