Heat oven to 375 degrees F.

In food processor, add flour, baking powder and baking soda, 3 tablespoons sugar. Pulse a few times to combine. Add butter to the mixture and pulse about 25 times, or until butter pieces are the size of small peas.

Empty into bowl, and starting with just 1/4 cup of the heavy cream, stir in gently until combined. Batter should be thick and slightly tacky. If the texture is crumbly, add a little more cream until it holds shape when gently squeezed. Add blueberries and gently stir until combined.

Turn out onto floured surface, knead a couple times and shape into 8 inch circle, about 1 1/2 inches thick.This is optional, but I pressed frozen berries into the top before baking (to add more berries and little flare).

Slice like pie into 8 pieces.

Bake for about 25 minutes until tops are golden brown
