Preheat your oven to 350 degrees. Wash your berries and set them in the freezer until we are ready to work them into the dough.
Whisk the flour, sugar, and baking powder in a large bowl. Stir in the heavy cream until your dough starts to come together. Finish mixing with clean hands. Fold in the berries.
Turn the dough out onto a floured surface. Roll to 1/2 inch thickness and cut into circles using a glass or biscuit cutter. Place on a baking tray and cook for 10 minutes or until lightly browned.
While your biscuits are cooling combine all of the glaze ingredients in a small bowl. Whisk until smooth and drizzle over your biscuits.
