So let me share with you how to make these healthy breakfast bars and use all your fresh strawberries!
How To Make Strawberry Slices
A strawberry slice is a three-layer slice made of one oat layer – some of this batter is then used for the third top layer of the strawberry bar.
And there are a few ingredients for the bar filling – the strawberry jam. But don’t worry, the recipe is pretty simple.
- Rolled oats – it means the larger kind of oats. This contains more fiber than quick oats, so it’s my favorite option. However, quick oats or instant oats work well here.
- Oat flour – it’s basically old-fashioned rolled oats pulsed into flour in your high-speed blender. You can swap this with almond flour or all-purpose flour.
- Maple syrup or any liquid sweetener you love, including agave syrup and honey.
- Vanilla extract
- Melted coconut oil or melted butter.
Jam Layer Ingredients
For the jam layer, you need:
- Fresh strawberries – or frozen strawberries slices, thaw overnight in the fridge or at least 3 hours before using in the recipe.
- Maple syrup or brown sugar
- Lemon juice
- Cornstarch or cornflour
Preheat oven to 350°F (180°C). Line an 8-inch x 8-inch baking pan with parchment paper. Slightly oil the paper with coconut oil. Set aside.
In a mixing bowl, combine all the ingredients for the bottom layer together. Start stirring with a spoon, then squeeze the batter with your hand to bring all the ingredients together.
It should be slightly dry but hold together when squeezed. If not, add a bit more maple syrup or 1 tablespoon of water to bring it together.
Set aside 1/2 cup of the mixture in a bowl – you will use this layer in the recipe.
Press the remaining batter into the prepared baking dish. Press firmly with a spatula until no holes can be seen.
Refrigerate while making the fruit jam.
How To Slice Strawberries
The next step consists of cleaning the fresh strawberries under tap water in a sieve.
Then hull the strawberries by cutting out the green part. Finally, place the strawberries on the side on a chopping board and lice, as seen in the picture below.
Place the sliced strawberries in a saucepan, along with the remaining ingredients for the filling: cornstarch, vanilla, lemon juice, lemon zest, and maple syrup.
Bring saucepan over medium-high heat and cook, occasionally stirring, until it forms bubbles in the pan and the liquid thickens and looks like a shiny jam.
Remove the saucepan from the heat and set it aside.
Assembling The Slice
Now remove the baking dish from the fridge and spread the strawberry jam evenly on top of the bar.
Crumble up the remaining 1/2 cup oat mixture on top of the bar.
Bake the strawberry oat bars on the center rack of the oven for 20-30 minutes or until the strawberry jam is bubbly and the top of the slice is golden brown.
Cool completely on a wire rack before slicing. Pull out the bar from the baking dish using the hanging part of parchment paper on the side of the dish.
Release on a chopping board and cut into 16 bars.
Store the strawberry oatmeal bars in the fridge in a sealed container for up to 4 days.
To freeze, place the bars in an airtight box or bag and freeze for up to 3 months. Thaw the strawberry bars at room temperature.
These strawberry slices are delicious on their own as a healthy breakfast or kid snack for a school lunchbox.
We also love this recipe served with some of the toppings below:
- A scoop of vanilla ice cream
- A dust of powdered sugar
- Drizzle some extra maple syrup
- Whipped Cream
- Almond Butter
- Corn-free – you can replace cornflour with 2 tablespoons of chia seeds or tapioca flour.
- Oat-flour swap – you can use the same amount of all-purpose flour or a gluten-free all-purpose flour blend.
- Maple syrup replacement – any liquid sweetener works. Brown sugar can be used for the strawberry filling but not for the crumble mixture.
- Strawberries alternative – the same amount of blueberries, raspberries, or mixed berries work well in this recipe.
