Why This Recipe is a Winner
- Pumpkin puree adds lots of moisture, color, and flavor, creating a dense and delicious cake
- Cornstarch helps to create a lighter crumb, softens the protein in the gluten, and acts as a binder
- Pumpkin pie spice adds the perfect blend of seasonings, delivering a delicious seasonal flavor to this fall dessert.
You can find the full printable recipe, including ingredient quantities, below. But first, here are some explanations of ingredients and steps to help you make this recipe perfect every time.
- Lemon — We’ll use both the zest and the juice of the lemon.
- Oats — I used rolled oats for this recipe, but you can substitute instant oats.
- Chia — We’ll add some ground chia seeds to create a thicker texture. You can use whole chia seeds; I just prefer ground because it creates a smoother finished texture.
- Syrup — I used maple syrup, but you can substitute agave nectar.
- Milk — We’ll use almond milk for the best overnight oats! Substitute your favorite plant-based milk.
- Yogurt — I love adding some plant-based yogurt (plain, unsweetened) for an even more tangy flavor.
- Protein Powder — I add some vanilla protein powder for increased flavor and nutrients. If your protein powder is not sweetened, you may want to add an extra teaspoon or two of sweetener.
- Cornstarch — We’ll use cornstarch to thicken the lemon curd topping.
- Turmeric — A pinch of turmeric makes that lemon curd sunny yellow.

Ever experience a cake failure? Here are my best tips on how to fix undercooked cake.
Does Pumpkin Cake Have to Be Refrigerated?
Pumpkin cake will keep at room temperature for up to 4 or 5 days. So, if you’ll be eating it within that time-frame, it will be fine. However, if it’s unusually warm in your kitchen or if you will be taking longer to eat it, it should be refrigerated.
- Create a pumpkin spice birthday cake by adding candles or baking it as a layer cake.
- Make pumpkin spice cake muffins by distributing the batter into muffin pan compartments. Cook them for 20 to 25 minutes.
Most recipes for pumpkin spice cake use canned pumpkin puree, meaning you can make this delicious cake all year round!
