Ingredients
Shortbread Crust and Topping
- 2 ¼ cups all-purpose flour
- ¾ teaspoon salt
- ¾ cup unsalted butter, at room temperature
- ¾ cup granulated sugar
- 1 teaspoon pure vanilla extract or vanilla bean paste
- ¾ cup Bob’s Red Mill extra thick rolled oats
- 3-4 tablespoons confectioners’ sugar
Lemon Curd
- ¾ cup granulated sugar
- 3 tablespoons lemon zest, finely chopped
- 4 egg yolks
- 6 tablespoons freshly squeezed lemon juice
- ¼ cup unsalted butter
- ¼ teaspoon salt
Red Currant Filling
- 2 cups red currants (fresh or frozen)
- ¼ cup granulated sugar
Preparing the Shortbread Crust and Topping

Preheat and Prepare the Pan
First, preheat your oven to 350°F. While that’s happening, choose an 11″ x 8″ tart pan with a removable bottom, a 10″ springform pan, or a quarter sheet pan lined with parchment paper. This ensures easy clean-up and beautiful bars!
Mix Flour and Salt
In a medium-sized bowl, whisk together the salt and flour. It’s okay if it takes a minute; just be sure everything is combined. Set this mixture aside for now.
Cream Butter and Sugar
Now, let’s beat the room-temperature butter and granulated sugar. Using a stand mixer with the paddle attachment, whip them on medium/high speed for about 5 minutes until fluffy. It’s essential to scrape the bowl’s sides as you mix to ensure a well-blended mixture. Once fluffy, add in the vanilla and blend once more.
Combine Dry Ingredients
Slowly reduce the mixer speed to low. Begin to gradually add the flour mixture and mix until the dough is crumbly but holds together when pressed.
Form the Crust
Next, set aside ¾ cup of the dough. With the rest, evenly spread it into the bottom of your prepared pan, pressing gently to hold it in place. Make sure it slightly climbs up the sides; it’s all part of the charm!
Bake the Crust
Bake this crust for about 25 minutes until it turns golden brown and puffy. Your kitchen will smell heavenly during this process!
Make the Oat Crumble
While that’s baking, combine the reserved dough with the oats using your fingers until evenly mixed. Pop this mixture into the fridge until you’re ready to use it. This ensures a lovely crumble texture when baked.
Preparing the Lemon Curd and Red Currant Filling
Combine Ingredients for Lemon Curd
Now, let’s get that zesty lemon curd ready! In either a bowl or the top of a double boiler, whisk together the sugar, lemon zest, and egg yolks. Place it over some simmering water and whisk continuously until the sugar dissolves.
Add Lemon Juice and Cook
As you’re whisking, start adding the lemon juice. Continue to stir while cooking for about 5 minutes. Then, toss in the butter and salt, stirring constantly until it thickens; this should reach about 170°F, creating a luscious lemon curd.
Strain the Curd
To ensure smooth curd, strain it through a fine mesh sieve and set this aside. If you’re not using it immediately, cover with plastic wrap and refrigerate.
Prepare Red Currants
In another bowl, gently toss your red currants with the granulated sugar. This simple step allows the fruit to sweeten a bit while you finish the preparation.
Assemble and Bake
Layer the Ingredients
Start layering your beautiful creation! Spread the lemon curd evenly over the baked crust. Next, add the sugared red currants on top. Finally, sprinkle the oat crumble mixture generously over everything. For an extra pop of color, dot a few additional currants on top.
Bake the Bars
Bake the assembled bars for 35-40 minutes, rotating the pan halfway through. You’ll know they’re ready when the topping is slightly browned and the filling is softened and deepened in color.
Cool and Slice
Post-baking, dust the top with confectioners’ sugar for a finishing touch. Then, let it cool slightly before removing from the pan and slicing into 12 equal bars. They look stunning, don’t they?
Serving Suggestions
These delightful bars can be enjoyed warm or cold. For an extra treat, serve alongside a scoop of vanilla ice cream or with a dollop of whipped cream. The options are endless!
Tips for Success
- For a richer flavor, let the butter sit out at room temperature for a few hours before you mix it. This allows it to become nice and fluffy!
- Be sure to whisk the lemon curd continuously to avoid curdling. It may seem tedious, but trust me, it’s worth the extra effort.
Variations
Want to mix things up? Consider substituting different berries like blueberries or raspberries for a twist that suits your taste buds! You can even add chopped nuts to the crumble for added texture and crunch.
