Preheat the oven to 350°F. Line a cupcake pan with liners.
To make the batter: In a large bowl (or using a hand mixer or stand mixer) add the sugar, canola oil, heavy whipping cream, eggs, and vanilla extract. Whisk together.
Add in the cake flour, baking powder, and sea salt in that order and whisk to combine into a smooth batter.
Fill the cupcake liners three-quarters full.
Bake for 20 to 24 minutes or until a toothpick inserted in the center comes out clean.
Slice strawberries.
To make the frosting: In the bowl of a stand mixer fitted with the whisk attachment (or using a hand mixer) add the heavy whipping cream, powdered sugar, and vanilla extract. Whisk starting on low to avoid splattering, and gradually increase the speed as the frosting thickens, until you are at full speed. Whisk until stiff peaks form.
Transfer the frosting to a piping bag with Ateco tip #808 (or no tip at all). Pipe frosting onto the cupcakes.
Top with fresh strawberries and serve immediately.
Store extra cupcakes in the fridge for up to 3 days.
