Crumb cake was actually created in Germany, and thank goodness it was! I can’t imagine my life without this delicious treat.
The great thing about making crumb cake is that you can change the ingredients. Sweet potatoes are one of my favorites, but you can also make fruit crumb cakes, too.
This recipe comes from a friends’ cookbook: Grandbaby Cakes by Jocelyn Delk Adams. Her cakes are LEGIT!
Ingredients in Sweet Potato Coffee Cake
The flavor of this dessert doesn’t showcase how easy this recipe really is! Just a few easy ingredients are all you’ll need.
- All-purpose flour – make sure that there aren’t any lumps in the flour.
- Granulated sugar – needed to sweeten the cake and the streusel topping.
- Brown sugar – boosts that sweetness factor!
- Ground cinnamon – you can never have too much cinnamon.
- Unsalted butter – the butter needs to be melted prior to use.
- Eggs whites and yolks separated – eggs need to be at room temperature.
- Vegetable oil – coconut oil would work as well.
- Sweet potatoes roasted, peeled, and mashed
- Hot water – the temperature of the water is important!
- Vanilla extract – adding vanilla always enhances the flavor.
- Baking powder – helps with the texture.
- Baking soda – adds a fluffy texture.
- Ground cloves – pairs perfectly with the cloves and nutmeg.
- Salt – just a pinch.
- Ground nutmeg – nutmeg adds a great warmth of flavor.
How to make this Sweet Potato Dessert
- This is one of my favorite sweet potato dessert recipes, and I think you’re going to love it as well!
- Preheat: Preheat the oven to 350°F. Line a 9×13” pan with foil or parchment paper and spray with nonstick cooking spray.
- Make the streusel: in a medium bowl, whisk flour, brown sugar, granulated sugar, and cinnamon. Slowly add melted butter and whisk until crumbs are formed. The mixture will look wet, but it’s supposed to look that way.
- Beat the eggs: In the bowl of a stand mixer fitted with the whisk attachment, beat the egg whites on high speed until stiff peaks form. Transfer the egg whites to a small bowl and chill until ready to use.
- Combine: Clean your stand mixer bowl and switch to the paddle attachment. Beat the granulated sugar and oil on medium-high speed until combined. Add the egg yolks 1 at a time, combining well after each addition and scraping down the sides of the bowl as needed. Add the mashed sweet potatoes, hot water, and vanilla and beat for another 3-4 minutes.
- Add the dry ingredients: Turn your mixer to its lowest speed and carefully add the flour, baking powder, cinnamon, cloves, salt, baking soda, and nutmeg. Mix until the batter is just combined, being careful not to over-mix. Remove the egg whites from the refrigerator and gently fold them in using a spatula or wooden spoon.
- Pour: Pour half the batter into the prepared pan. Top with half the streusel. Repeat with remaining batter and streusel. Bake for 55-65 minutes until a toothpick comes out moist but mostly clean. Let cool in the pan.
Storing and Freezing Instructions
Serve warm or at room temperature. Store tightly covered at room temperature for up to 3 days.
Expert Tips
You want to be very careful that you don’t overmix the ingredients. Also, if you can, use an egg separator for the whites and the yolks for the best results.
Make sure to follow the steps to make the crumble topping perfectly. It’s the star of the sweet potato show!

I would always pick a sweet potato over a regular one ? Favorite family recipe is my mom’s tomato sauce and her meatballs (they are the best!)
On my list for this weekend! Can’t wait!
This looks delicious. I love sweet potatoes.
This is not my favorite family recipe but it’s my husband & daughter’s … tuna macaroni salad. Simple and they love it! I have to make it all the time for them. That is a beautiful cook book cover!
We gave a chocolate chip cookie recipe that our family is known by at church.
