How to Make Sweet Potato Apple Cake

Prepare Sweet Potatoes: Wash, peel, and cook the sweet potatoes until tender-either boil for 20-30 minutes or roast at 400°F (200°C) for about 45 minutes. Once soft, mash them to yield about 1½ cups of creamy goodness.
Grate Apples: Peel, core, and coarsely grate the Gala apples. Make sure to lightly squeeze out excess moisture, but retain some juice to enhance the flavor in your cake.
Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, cinnamon, nutmeg, and ginger until well combined. This blend will add delightful warmth to your cake.
Combine Wet Ingredients: In another bowl, mix the vegetable oil, light brown sugar, eggs, and vanilla extract until smooth. Stir in your freshly mashed sweet potato and grated apples until everything is well incorporated.
Combine Mixtures: Gently fold the wet mixture into the dry ingredients, being careful not to overmix. You want just combined batter for a light and fluffy cake.
Bake: Preheat your oven to 350°F (175°C). Pour the batter into a greased baking pan and bake for 35-40 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
Cool & Glaze: Allow the cake to cool in the pan for about 15 minutes before transferring it to a wire rack. For the optional glaze, whisk together melted butter and brown sugar, then brush it over the warm cake for added richness.

Optional: Serve warm with a dollop of crème fraîche or a scoop of vanilla ice cream for an indulgent touch.

Expert Tips for Sweet Potato Apple Cake

Choose Fresh Ingredients: Use ripe sweet potatoes and fresh apples for the best flavor. Older ingredients can lead to a dull taste in your Sweet Potato Apple Cake.
Avoid Overmixing: Gently fold the mixtures to prevent a dense cake. Overmixing can make your cake tough instead of light and fluffy.
Roasting Sweet Potatoes: Opt for roasting your sweet potatoes for deeper flavor. This enhances the natural sweetness compared to boiling.
Customize Your Apples: Experiment with different apple varieties like Honeycrisp or Fuji to add unique tastes and textures to your cake.
Check for Doneness: Use the toothpick test and aim for moist crumbs to achieve perfect texture. A dry toothpick indicates overbaking.
Add Fun Mix-Ins: Consider folding in chopped nuts or dried fruits for extra flavor and texture in your Sweet Potato Apple Cake.

How should I store leftover Sweet Potato Apple Cake?
To keep your cake fresh, store it in an airtight container at room temperature for up to 3 days. If you find that you have more cake than you can eat, refrigerate it for up to 5 days, ensuring it's tightly wrapped to maintain moisture.
