Preheat oven to 375 degrees.Add strawberries and maple syrup to a medium saucepan. Cook on medium heat for 15 minutes stirring occasionally. Meanwhile add the lemon juice and cornstarch to a small bowl and whisk until the cornstarch has dissolved. Set mixture aside.
Add the cornstarch slurry to the saucepan and cook for another minute or two or until thickened. Stir in lemon zest.
To a large bowl add the oats, almond flour, coconut oil, maple syrup, salt and vanilla extra.
Stir to combine and set aside.
Grease an 8 x 8 baking dish with nonstick cooking spray. Cover with parchment paper. (The nonstick cooking spray helps the parchment to stick)Add half of the crumb mixture to the prepared pan. Using your fingers press the mixture into the bottom of the pan.
Spread the strawberry jam mixture on top. Then top with the remaining oat crumble and bake for 25-30 minutes or until the top looks set and golden brown.
Allow these bars to cool completely or they will make a huge mess. I like to pop them in the freezer to chill down faster. This also makes them a lot easier to cut.Slice, serve and enjoy!
