Preheat the oven to 350°F (175°C).
Place the butter pieces evenly on the bottom of an 8-inch pie dish.
In a medium bowl, add the berries, sugar, cornstarch, salt, vanilla, orange zest, and lemon juice, gently folding until thoroughly combined.
Spread mixture evenly into prepared dish.
In a separate medium bowl, whisk together flour, almond flour, sugar, baking powder, and salt. Stir in milk, melted butter, orange zest, and vanilla until just combined - it’s okay if it has a few lumps.
Pour the batter over the berries, spreading it evenly. Sprinkle the almond slices on top.
Bake for 25-35 minutes or until the cobbler is golden brown and a toothpick inserted into the center comes out clean.
Allow it to cool for about 15 minutes before serving.
Serve the cobbler warm, with whipped cream or vanilla ice cream.
