A crumble bar that tastes just like pie. Say what?! Sweet strawberry and rhubarb jammy filling sandwiched between a buttery shortbread base and crumble topping, seriously they are amazing. Heartwarming and nostalgic, these Small Batch Strawberry Rhubarb Crumble Bars will have you reaching for another.
The sweet flavours of strawberry combined with the tartness of the rhubarb go together like chocolate and hazelnut! Basically they are two flavours worth pairing together. Trust me! Another small batch recipe aimed to help those in low number households during this lockdown. It’s the 8th in my Small Batch Series and one of my personal favourites. Maybe I say that because of my love for rhubarb, or its just because I love the ease in making them.
For these Strawberry Rhubarb Crumble Bars you will need:
For the base:
- Flour: the base ingredient for the crumble base and topping
- Golden Sugar: I use golden sugar but by all means sub with white sugar or light/dark brown sugar. The darker the sugar you use the depth of flavour in the topping will deepen.
- Old Fashioned Oats: provide a beautiful texture, particularly to the topping
- Baking Powder: to provide some lightness to the base and topping
- Salt: cuts through the sweetness. I always add salt to my desserts
- Butter: Helps bind the ingredients together and once baked allows the base in particular to be flaky and short. The perfect texture.
- Egg Yolk: The main binding agent and add a slight richness to the crumble topping and base. If doubling the recipe then adds a whole beaten egg into your mixture.
For the Filling:
- Strawberries and Rhubarb: When baked together these breakdown and their juices merge to create a sweet jammy filling.
- Lemon Juice: this helps cut through the sweetness. If you don’t have any then don’t worry, carry on with the recipe.
- Sugar: As the filling cooks the sugar combines with the fruit to help create the sweet sticky filling. Also needed to offset the sour rhubarb.
- Cornstarch: Helps to thicken the filling. Strawberries can contain a high water content and the cornstarch stops it from becoming too watery.
How do you make these crumble bars?
I am such a fan of crumble bars as they combine the tastes of a fruit pie in a really easy manner of making. With no need for pie pastry that requires refrigeration and waiting times. This beautiful crumble bar can be made in 15 minutes only. Quick and easy! We looooove quick and easy desserts around here.
Step 1 Make the crumble base and topping.
Talking of easy – these two separate components are made in one go!
Add your dry ingredients, flour, sugar, oats, baking powder and salt into a medium bowl and mix. Add the cubed butter and with your finger tips rub the butter into the flour until it resembles breadcrumbs. Add the yolk and mix until combined.
Step 2: Make the filling.
Add all the filling ingredients, strawberries, rhubarb, lemon juice, sugar and cornstarch, into a medium bowl and stir to combine.
Step 3: Assemble
Add 2/3 of the crumble filling to a prepared loaf pan. Using your finger tips to press the mixture flat into the pan. This is your base. Then add all the filling onto of the base and spread out evenly. Lastly sprinkle the remaining crumble onto the filling allowing some of the filling to still show. Then bake for 45 minutes!
Top Tips to make these Strawberry Rhubarb Crumble Bars
- When lining the loaf pan with baking paper. Ensure that the paper hangs over the sides of the pan. Once the bar is cooked and then cooled, having the paper overhang will help you pull the pars out.
- Make sure your butter is cold. Just like pastry if you use warm butter, when baked you’ll end up with a greasy base. The cold butter allows for a flaky crust which is perfect.
- Cut the rhubarb into 1/4 inch slices to ensure that it cooks in the allotted time.
- Ensure that you use the freshest strawberries for maximum flavour impact. If your strawbs aren’t at their freshest then add two tablespoons of strawberry jam/preserve into the fruit filling. This help intensify the strawberry taste.
- Lots of fruit is good! When you pour the filling on top of the base it will look like a lot. But trust me, go with it. As the fruit cooks it will reduce down and intensify into jammy goodness!
- Let the bars cool before slicing if you want beautiful clean slices. But if you aren’t fussed about this then tuck right in with a dollop of ice-cream (recommended serving suggestion!)
