Step 2
Preheat the oven to 400°F. Sift together flour, sugar, baking powder, baking soda, and salt. Using a spoon or silicone spatula, mix in heavy cream until just combined.
Step 3
Place mixture in an ungreased 8X8 inch pan. Bake until golden, about 18-20 minutes. Cool 10 minutes before removing from the pan and placing on a wire rack to cool.
Step 4
Add the heavy cream, sugar, vanilla extract, and lemon zest to a large bowl. Using a mixer, beat starting on low speed and moving up to high speed for about 2 minutes or until soft peaks form.
