Whisk together the flour, baking powder, sugar and salt for the scones and place in the fridge.
Whisk together the egg, vanilla extract, and yogurt/coconut cream and set aside.
Cut your butter into cubes and add it to the flour mixture. Use a pastry cutter or fork to cut in the butter until you have a sand like texture, with little pea-sized bits of butter (the butter should be mostly broken down, but not melted).
Add the remaining wet ingredients and use a fork to combine the dough until it holds together. If it is not coming together, add more yogurt/coconut cream 1 tablespoon at a time.
Mix in your raspberries then form the dough into a disk on a parchment lined baking sheet. The disk should be about 8-9 inches in diameter and about an inch thick. Place the dough in the fridge for 30 minutes.
While dough rests, make your crumble topping by mixing all crumble ingredients together with a fork.
Preheat the oven to 350F.
When ready to bake, top the scones with the crumble topping, pressing down gently. Slice the dough into 8 scones and separate them on the baking sheet. They will expand during baking.
Bake for ~30 minutes until golden.
Let cool for 10 minutes on the baking sheet before transferring to a wire rack to finish cooling.
When ready to serve, mix together ¼ cup of powdered sugar with 1 tablespoon of yogurt/coconut cream until you have a thin mixture. Add more yogurt if it is too thin. Drizzle over the scones and enjoy!
