Step 1: Preheat your oven to 350°F (175°C) and gather all your ingredients.
Step 2: In a round cake pan, melt the unsalted butter over low heat. Sprinkle the brown sugar evenly over the butter and arrange the halved loquats cut side up on top.
Step 3: In a large mixing bowl, whisk together the all-purpose flour, baking powder, and salt.
Step 4: In another bowl, whisk together the granulated sugar, vegetable oil, eggs, and vanilla extract until smooth. Gradually add the milk and blend until well combined.
Step 5: Carefully add the wet mixture to the dry ingredients and stir gently until just combined.
Step 6: Pour the batter over the arranged loquats in the cake pan and spread it evenly.
Step 7: Bake for about 40-45 minutes, or until a toothpick inserted in the center comes out clean.
Step 8: Let the cake cool in the pan for 10-15 minutes, then invert onto a serving platter.
Step 9: Serve warm or at room temperature, optionally with vanilla ice cream or whipped cream.
Notes
Make sure your loquats are ripe but firm. For a deeper flavor, consider adding a teaspoon of ground cinnamon or nutmeg to the dry ingredients.
