In a medium bowl, whisk together the flour, baking powder, baking soda and salt. Set aside.
2 1/2 cups (300g) all-purpose flour, 1 Tbsp baking powder, 1/4 tsp salt, 1/2 tsp baking soda
In a large bowl whisk together the melted butter and sugar until they’re well combined.
1/2 cup (113g) salted butter, 1 1/4 cup (250g) granulated sugar
Add in one egg and whisk until it’s well combined and has lightened in color, about 30 seconds. Repeat with the next two eggs, one at a time.
3 large eggs
Add in the Greek Yogurt and the vanilla extract and whisk until it’s completely smooth.
3/4 cup (170g) Greek Yogurt, 2 tsp pure vanilla extract
Add in the heavy whipping cream and whisk until it’s completely smooth.
3/4 cup (6oz) heavy cream
Add in the dry ingredients and mix just until the last streak of flour is incorporated.
Toss the blueberries with the cornstarch and fold them into the batter, just until they’re almost evenly distributed. Don't over-mix or you'll color the whole batter blue (if they're frozen).
1 1/2 cups (210g) wild frozen blueberries, 1 Tbsp (7g) cornstarch
Preheat the oven to 350F (177C) and grease and line a 10 inch springform pan.
Spread the batter into the prepared pan, sprinkle with a few more blueberries and 1-2 Tbsp of granulated sugar for a crispy muffin-like top.
2-3 Tbsp sugar
Bake for 45 minutes, until it's golden brown on top and a toothpick comes out clean. Remove from the oven and allow to cool for at least 30-60 minutes before serving.
Top with a dusting of powdered sugar and/or fresh whipped cream or more fresh blueberries.
