These Gluten-Free Raspberry Bars feature a buttery oat and almond flour crust, a naturally sweet raspberry filling, and a crumbly topping that bakes up golden and crisp.
Preheat the oven to 350°F. Line an 8x8 baking dish with parchment paper.
In a food processor, combine the almond flour, oats, coconut flour, honey, and salt. Pulse a few times to mix. Add the cold, cubed butter and pulse until the mixture forms coarse crumbs.
Press ⅔ of the mixture into the bottom of the prepared pan to form a crust. Bake for 10 minutes.
In a medium saucepan over medium heat, combine the raspberries, honey, lemon juice, and vanilla extract. Cook for 5–7 minutes, stirring often, until the berries break down and become saucy.
Stir in the cornstarch and cook for 1–2 more minutes until thickened. Remove from heat and let cool slightly.
Spread the cooked filling evenly over the partially baked crust.
Crumble the remaining oat mixture evenly over the top of the filling.
Bake for 25 minutes, or until the topping is golden and the filling is bubbling.
Cool completely in the pan. For clean slices, chill in the fridge for 1–2 hours before cutting.
