Ingredients for banana cake crock pot
Six simple ingredients plus optional mix-ins for a cake that feels indulgent yet effortless.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 medium | Mashed, about 1.5 cups |
| All-Purpose Flour 🌾 | 2 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 cup | White or brown preferred |
| Vegetable Oil 🫒 | ½ cup | Light or canola oil |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Baking Powder 🧂 | 2 tsp | Aluminum-free for best rise |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated for warmth |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Vanilla Extract 🥛 | 1 tsp | Pure vanilla preferred |
| Walnuts 🌰 | ½ cup | Chopped, optional topping |
| Semisweet Chocolate Chips 🍫 | ½ cup | Enjoy Life brand for allergies |
The bananas are the star—overripe ones pack the most flavor, but any ripe bananas work. Trader Joe's and Whole Foodsg usually have the best selection of spotty ones. If you can't find overripe, slightly green bananas will work but need longer cooking time. The flour matters too—King Arthur or Bob's Red Mill brands give the best texture. Sift it before measuring to avoid dense cake. I always double-check the baking powder expiration date—old leavening is the #1 reason cakes fail.
No vanilla extract? Vanilla bean paste works in a pinch, or even a pinch of vanilla sugar. Short on walnuts? Pecans or chopped dates add sweetness and texture. Chocolate chips optional, but Enjoy Life brand is my go-to for allergy-friendly baking. The oil can be swapped for melted butter (same amount) if you prefer. Just make sure it's room temperature—cold butter creates lumps. For extra moisture, add 2 tbsp of applesauce to the batter. The nutmeg is non-negotiable though—it's what makes this taste like real banana cake.
This batter keeps 2 days in the fridge if you're prepping ahead. The walnuts and chocolate chips can be stored separately and added fresh before serving. When reheating, cover the crock pot with a lid or foil to keep it moist. Leftovers reheat beautifully—just 10 minutes on low restores that warm, gooey texture. The cake freezes surprisingly well too—up to 3 months if wrapped tightly. I always make a double batch because it disappears fast.
Why You'll Love This Recipe
- No Mixing Required: I swear by this recipe because it’s literally just dump-and-go. Mash those bananas, toss in the dry ingredients, and let the crock pot do the work—no electric mixer, no sifting, no stress. The eggs and oil bind everything together while you’re sipping coffee or scrolling through your phone.
- Spice That’s Actually Good: That caramelized sugar crust? Chef’s kiss. The ripe bananas turn into a deep, buttery sweetness, while the flour and eggs create a tender crumb that’s not too dense, not too cakey—just right. Honestly, I’ve made banana bread that tasted like a sad, mushy brick, but this? It’s the kind of cake you’ll eat straight from the pot.
- Leftovers for Days: Between us, this recipe makes two full cakes in one go. That means breakfast for the week, a snack for your kid’s school lunch, or even a midnight treat when you’re craving something sweet but don’t want to bake. I’ve had slices for days, and they stay moist—no dry, sad cake here.
- Budget Breakfast Win: You’re using pantry staples—flour, sugar, eggs—and turning overripe bananas into something magical. No fancy ingredients, no markup, just solid, reliable flavor that won’t break the bank. Plus, it’s cheaper than buying a pre-made cake, and way better than store-bought banana bread.
Step-by-step instructions for banana cake crock pot recipe
Here's how to create a moist, spiced banana cake with minimal effort—no oven required.
👨🍳 Step 1: Mix the Dry Ingredients
In a medium bowl, combine the 2 cups all-purpose flour, 2 teaspoons baking powder, 2 teaspoons ground cinnamon, ½ teaspoon ground nutmeg, and ½ teaspoon salt. Whisk everything together until smooth—you should see no lumps remaining. I like to sift the flour first for an even lighter texture, but whisking works too if you're short on time.
Set this mixture aside while you prep the wet ingredients. The spices will infuse the entire cake, so make sure they're evenly distributed. If you're using freshly ground cinnamon or nutmeg, you'll notice an even more aromatic flavor compared to pre-ground versions.
🍳 Step 2: Combine Wet Ingredients
In a separate large bowl, mash the 3 medium ripe bananas until smooth—about 1.5 cups of mashed banana. Add the 1 cup granulated sugar, ½ cup vegetable oil, 2 whole large eggs, and 1 teaspoon vanilla extract. Mix everything together until fully combined and creamy.
This is where the magic happens—the bananas add natural sweetness while keeping the cake moist. I always let the bananas sit at room temperature for 10 minutes before mashing to make them easier to blend. If your bananas are extra ripe with brown spots, that's perfect—they'll be even sweeter and create a richer cake.
🥘 Step 3: Mix Wet and Dry Ingredients
Gradually add the dry ingredients to the wet mixture, stirring gently just until combined. Be careful not to overmix—once everything is incorporated, stop stirring. The batter should be thick but pourable.
Fold in the ½ cup semisweet chocolate chips and ½ cup chopped walnuts by hand using a spatula. I like to distribute the chocolate chips evenly throughout, with a few extra sprinkled on top before baking. The walnuts add a nice crunchy texture that contrasts beautifully with the soft cake.
⏰ Step 4: Prepare the Crock Pot
Lightly grease a 6-quart slow cooker with vegetable oil or line it with parchment paper for easy removal. Pour the batter into the crock pot and smooth the top with a spatula. If you want extra browning, sprinkle a thin layer of granulated sugar on top before cooking.
Cover the crock pot and cook on high heat for 3 to 3.5 hours. I check it at the 2.5-hour mark—the cake is done when a toothpick inserted in the center comes out clean with just a few moist crumbs. The cake should be golden on top and slightly springy to the touch.
🍽️ Step 5: Serve Warm and Enjoy
Let the cake cool in the crock pot for 10 minutes before carefully removing it. If you lined the crock pot with parchment paper, it should lift right out with the cake intact. Transfer to a serving plate and let it cool for another 10 minutes before slicing.
Serve warm with a dollop of whipped cream or a scoop of vanilla ice cream. The cake will be moist, tender, and infused with warm banana and spice flavors—perfect for a cozy dessert without turning on the oven. Store leftovers in an airtight container in the refrigerator for up to 3 days, or freeze slices for up to 2 months.
Pro Tips For Making Banana Cake Crock Pot
- MASH THE BANANAS FIRST: I learned this the hard way—adding whole bananas to the crock pot just makes for a lumpy, uneven mess. Mash them with a fork first, then mix in the wet ingredients. If you’re using very ripe bananas, you might not even need extra liquid—they’ll release enough moisture on their own.
- USE LOW HEAT FOR EVEN COOKING: Crock pots love patience. High heat will dry out the cake before it’s fully set. Start on low for 3–4 hours, then switch to warm if it needs more time. The center should jiggle slightly when done—overbaking turns it into a brick.
- SIFT THE FLOUR TO AVOID DENSE CAKE: Packed flour means a heavy, gummy cake. Sift the dry ingredients (flour, baking powder, salt) directly into the crock pot before adding the wet mix. This also cuts down on lumps and guarantees a lighter texture—trust me, it’s worth the extra 30 seconds.
- SWAP VEGETABLE OIL FOR BUTTER (IF YOU DARE): Vegetable oil keeps this cake moist, but butter adds depth. Melt ½ cup butter and cool it slightly before mixing—it won’t curdle the batter like cold butter would. The flavor upgrade is noticeable, especially if you’re serving it with coffee or ice cream.
Perfect pairings for these flavors
Classic Whipped Cream
Whipped cream is the ultimate classic pairing for this warm banana cake. I use Cool Whip for convenience or make homemade with heavy whipping cream and a pinch of vanilla. For extra flair, dust with powdered sugar or a sprinkle of cinnamon before serving. The coolness of the cream contrasts beautifully with the warm spiced cake, balancing the flavors perfectly. 🥛
Caramel Drizzle
A rich caramel sauce takes this dessert to the next level. I recommend Storebrand Caramel Sauce or homemade with ½ cup brown sugar, ¼ cup butter, and ¼ cup heavy cream. Drizzle generously over each slice or create a caramel pool in the center of the plate. The buttery sweetness complements the banana's natural sugars without overpowering the spice notes.
Vanilla Ice Cream
For a nostalgic twist, serve slices of cake with a scoop of bluebell vanilla ice cream or Breyers. The cold, creamy texture contrasts wonderfully with the warm cake. I like to let the ice cream soften slightly before serving so it doesn't melt too quickly. A drizzle of warm caramel on top creates a "sundae" effect that's hard to resist. 🍦
Warm Spiced Applesauce
For a lighter option, try serving with warm spiced applesauce. Simmer 1 cup applesauce with ½ tsp cinnamon, ¼ tsp nutmeg, and 1 tsp maple syrup until heated through. The apple's natural sweetness and warm spices harmonize perfectly with the banana cake, creating a balanced dessert experience. This pairing is especially great for those watching their sugar intake.
Chocolate Ganache Dip
Melt ½ cup semisweet chocolate chips with ¼ cup heavy cream for a decadent chocolate ganache. Dip the cake slices halfway into the ganache before serving. The chocolate's bitterness contrasts the cake's sweetness while adding a luxurious touch. I often pair this with a sprinkle of crushed peppermint for a festive holiday twist. 🍫
Fresh Berries
Add a pop of freshness with sliced strawberries or blueberries. The bright acidity cuts through the richness of the cake, creating a refreshing balance. I like to arrange the berries in a circular pattern around the plate for an elegant presentation. This pairing works especially well during summer months when berries are at their peak. 🍓

Frequently asked questions
Can I make this banana cake in a regular oven instead?
Transfer the batter to a greased 9x13-inch baking dish and bake at 350°F (175°C) for 45-55 minutes or until a toothpick comes out clean. The oven version cooks faster but may dry out slightly more than the slow cooker method. For best results, cover loosely with foil after 25 minutes to prevent over-browning.
Why does my crock pot banana cake turn out dense?
Overmixing the batter is the #1 culprit—stop stirring once all ingredients are combined. Also check your baking powder (must be fresh) and don't skip sifting the flour. For extra moisture, add 2 tbsp applesauce or 1 tbsp yogurt to the wet ingredients. The slow cooker's gentle heat should prevent dryness, but if it's still dense, reduce cooking time by 15 minutes.
How do I adjust this for gluten-free baking?
Replace the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill) plus ½ tsp xanthan gum. For best results, add 1 extra tbsp of oil to compensate for the lack of gluten structure. The texture will be slightly denser but still moist. Test with a toothpick at 2.5 hours since gluten-free cakes often cook faster.
Can I make this vegan? What substitutions work?
Yes! Replace the eggs with 2 tbsp flaxseed meal + 6 tbsp water (let sit 5 minutes to thicken) and use vegan butter or coconut oil instead of vegetable oil. For the sour cream topping (if using), substitute with vegan sour cream or mashed silken tofu. The cake will still be rich and moist, just with a slightly different texture.
What's the best way to reheat leftover banana cake?
For 1-2 slices, microwave for 10-15 seconds covered with a damp paper towel. For larger portions, wrap slices in foil and warm in the oven at 300°F (150°C) for 8-10 minutes. The crock pot method works too—place slices in a small dish with 1 tbsp water, cover, and cook on low for 10 minutes. Always reheat until warm through.
