1) Adjust oven rack to middle position and preheat oven to 350ºF /180ºC.
Butter and flour an 8-by 8-inch square pan.
Place the pan on an insulated baking sheet or on two regular baking
sheets stacked on top of the other (this helps even baking).
2) In a medium bowl, whisk the flour, baking powder and salt together,
set aside.
3) In a large bowl, rub the sugar, cinnamon, lemon zest, vanilla and
almond extract together until the sugar is moist and fragrant.
(We use our fingers to rub aromatics into the sugar.) Whisk in the eggs
until blended then whisk in the cream.
4) Switch to a large rubber spatula. Add the dry ingredients in 3 parts,
stirring gently until they disappear and the batter is smooth.
Fold in the melted butter in 2 parts. The batter will be smooth and
thick.
5) Spread about 1/3 of the batter in the bottom of the prepared baking
pan.
Fold in all but a handful of the blueberries to the remaining batter
left in the bowl.
6) Layer the blueberry-batter mixture on top of the batter already in
the baking pan.
Smooth the top then scatter remaining blueberries over the batter.
7) Bake 50 to 60 minutes, or until a knife inserted into the center of
the cake comes out clean.
When baked, transfer the cake, in the pan, to a wire rack to cool for 5
minutes.
Unmold the cake and place right side up on the rack. Cool completely
before serving.
Notes
1) To keep the blueberries from sinking, cut it half and make sure they
are dry.
Alternatively, toss the blueberries with a dusting of flour.
2) Substitute sour cream for greek yogurt.
3) When you combine vanilla extract with a little bit of almond extract
in butter cakes, the flavor is much better.
Your cake will taste like it came from a fancy bakery.
You won’t really be able to tell almond extract is in there, but the
cake will taste amazing.
