01 - Combine flour, yeast, sugar, and salt in a large mixing bowl. Pour in lukewarm water and olive oil, stirring until incorporated. Transfer to a floured surface and knead for 5-7 minutes until smooth and elastic. Place in a lightly oiled bowl, cover with a damp cloth, and let rise in a warm area for 1 hour until doubled in volume.
02 - Preheat oven to 450°F. Line a baking sheet with parchment paper. Punch down the risen dough and roll out on a floured surface to approximately 1/4 inch thickness. Form into a heart shape using your hands or a heart template, ensuring even thickness throughout.
03 - Spread tomato sauce evenly over the dough surface, leaving a 1/2 inch border for the crust. Season sauce with dried oregano, garlic powder, salt, and pepper. Distribute shredded mozzarella cheese across the sauce, then arrange beef pepperoni slices in an even pattern.
04 - Brush the exposed crust border with olive oil for golden coloring. Transfer to preheated oven and bake for 13-15 minutes until crust is deep golden brown, cheese is fully melted and bubbly, and pepperoni edges are slightly crisp.
05 - Remove pizza from oven and immediately scatter fresh basil leaves over the hot surface to release their aromatic oils. Allow to rest for 2-3 minutes before slicing to set the cheese. Serve warm while basil is still fragrant.
