Kitchen Utensils
- Mixing bowls
- Electric mixer or whisk
- Measuring cups and spoons
- Loaf pan (8×4 inches)
- Spatula
- Toothpick or cake tester
Ingredients
- 1/2 cup (115g) unsalted butter, softened
- 1/2 cup (130g) creamy peanut butter
- 1 cup (200g) granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup (120ml) sour cream
- 1 3/4 cups (220g) all-purpose flour
- 1 1/2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
How To Make Peanut Butter Loaf Cake Recipe
Step 1:
Start by preheating your oven to 350°F (175°C). Then, grab your loaf pan and give it a good greasing with butter or some non-stick spray. To make sure nothing sticks, you can also sprinkle a little flour on top or line the pan with parchment paper. This helps your cake come out perfectly every time!
Step 2:
In a big bowl, use an electric mixer or a whisk to beat together the softened butter, peanut butter, and sugar. Keep going for about 3 to 5 minutes until the mix looks light, creamy, and fluffy—that’s when you know it’s just right.
Step 3:
Now, add your eggs one at a time, beating well after each one so everything blends smoothly. Then stir in the vanilla and milk (or sour cream) until the batter feels nice and combined.
Step 4:
In another bowl, whisk together your flour, baking powder, baking soda, and salt. Slowly add this dry mix to your wet ingredients, alternating with any extra milk if the batter seems too thick. Mix gently and just until everything comes together—you don’t want to overwork the batter.
Step 5:
Pour your batter into the prepared pan and smooth out the top with a spatula. Pop it into the oven for 45-50 minutes. To check if it’s done, stick a toothpick in the middle—if it comes out clean, you’re good! Let the cake cool in the pan for about 10 minutes before moving it to a wire rack to cool completely.

Why Should You Make This Recipe
You should make this peanut butter loaf cake recipe because it’s rich, moist, and packed with real peanut butter flavor. It uses simple pantry ingredients and requires minimal effort, making it accessible even for beginner bakers.
The texture is soft but sturdy, making peanut butter loaf cake recipe easy to slice and enjoy anytime. It’s great for quick snacks, casual get-togethers, or just when you’re craving something homemade and satisfying.

My Tips For Success
● Make sure your butter, peanut butter, and eggs are at room temperature before you start. This helps everything mix together more smoothly and evenly.
● Take your time when creaming the butter, peanut butter, and sugar. That light and fluffy texture sets the stage for a soft, moist cake.
● Once you add the dry ingredients, mix gently—just until everything is combined. Over mixing can make the cake dense or tough.
● A standard 9×5-inch loaf pan works best. If you’re using a different size, you may need to adjust the baking time slightly.
● Oven temperatures can vary, so start checking for doneness around the 45-minute mark. A toothpick should come out clean or with a few moist crumbs—no wet batter.
● As tempting as it is to dive in right away, letting the cake cool completely helps the texture set and makes it easier to slice cleanly.

Additions For Make More Delicious
1. Swirl in melted chocolate or Nutella: Create a rich, gooey swirl by folding melted chocolate or Nutella into the batter before baking. This adds a luscious contrast to the peanut butter and makes each bite more indulgent.
2. Incorporate crunchy nuts: Mix in chopped roasted peanuts, walnuts, or pecans for a satisfying crunch that complements the smooth, creamy texture of the cake. Toasting the nuts beforehand boosts their flavor.
3. Add mashed ripe banana: Fold in a ripe mashed banana to naturally sweeten and moisten the loaf. The banana adds subtle fruity notes that pair beautifully with the nutty peanut butter taste.

Storage Recommendations
Keep the peanut butter loaf cake recipe in an airtight container at room temperature for up to three days to maintain freshness. For longer storage, wrap it tightly and refrigerate for up to a week.
To store even longer, freeze the peanut butter loaf cake recipe well wrapped for up to three months, then thaw it in the fridge before enjoying.
FAQs Your Peanut Butter Loaf Cake Recipe
Can I use natural peanut butter instead of creamy peanut butter?
Yes, natural peanut butter works well, but because it tends to separate and have more oil, you should stir it thoroughly before measuring. Using natural peanut butter may result in a slightly denser and oilier texture, but the flavor will be just as rich and delicious.
How can I tell when the peanut butter loaf cake is fully baked?
The best way is to insert a toothpick or cake tester into the center of the loaf. If it comes out clean or with only a few moist crumbs clinging to it, the cake is done. If there’s wet batter, it needs more time. Baking times can vary, so start checking around 45 minutes.
Is it possible to make this recipe gluten-free?
Absolutely! Replace the all-purpose flour with a gluten-free flour blend that’s designed for baking. Because gluten-free flours absorb liquids differently, you might need to slightly adjust the amount of milk or other liquids to keep the batter moist.
Can I freeze the baked peanut butter loaf cake?
Yes, freezing is a great option to keep the cake fresh longer. Wrap the cooled loaf tightly in plastic wrap or aluminum foil, then place it in a freezer-safe bag or container. It will keep well for up to three months. Thaw at room temperature or gently warm slices before serving.
Can I add mix-ins like chocolate chips or nuts?
Definitely! Adding mix-ins such as chocolate chips, chopped roasted peanuts, or even dried fruit can enhance both the texture and flavor of the cake. Fold them gently into the batter just before baking to evenly distribute.
Conclusion
This easy and delicious peanut butter loaf cake recipe is a wonderful way to enjoy the rich, nutty flavors you love with minimal effort. The simple ingredients come together quickly to create a moist, flavorful treat that’s perfect any time of day.
