Ingredient List for Peanut Butter Cake

Each ingredient in this Peanut Butter Cake serves a purpose, contributing to the overall flavor and texture. The key players are the cake mix, peanut butter, and butter, which together create a wonderful balance of sweetness and richness. Let’s dive into the specifics!
- Duncan Hines Butter Golden Cake Mix: This pre-packaged mix is a time-saver, providing a delicious base with a buttery flavor that complements the peanut butter perfectly.
- ¾ Cup Water (room temp): Water is essential to hydrate the ingredients and help bring the batter together into a smooth consistency.
- 3 Large Eggs (room temp): Eggs provide structure and moisture, helping the cake rise and ensuring a tender crumb.
- 7 Tbs Butter (use real butter that is room temperature): Real butter adds richness and flavor, creating a moist cake.
- 1 Cup Peanut Butter (smooth): The star of the show! Smooth peanut butter enhances the cake’s flavor and provides moistness, making every bite a delight.
- 1 tsp Vanilla Extract: Vanilla adds depth to the flavor profile, rounding out the sweetness beautifully.
Preparation Steps for Peanut Butter Cake

Let’s get started on creating this delightful Peanut Butter Cake. The steps are simple, and I’ll guide you through each one to ensure your cake turns out perfectly every time!
- Preheat your oven to 350°F (175°C). This is a crucial step to ensure your cake rises nicely. Prepare your baking pan by spraying it with baking spray, which will help the cake release easily once baked.
- If you’re using 9×9 round cake pans for a layered cake, cut parchment paper to fit the bottom of the pan. This extra step guarantees that your layers come out perfectly intact and easy to frost.
- In the bowl of a stand mixer, combine the cake mix, water, eggs, butter, peanut butter, and vanilla. Mix on medium speed until everything is well blended. You’ll want to see a fluffy batter with a bit of air whipped in—this typically takes about 2 to 3 minutes.
- Pour the batter into your prepared baking pan, smoothing the top with a spatula. Make sure to distribute the batter evenly to promote even baking.
- Place the baking pan on the center rack in your warmed oven. Bake for about 25 minutes. I recommend starting to check at the 20-minute mark to avoid over-baking.
- To check if the cake is done, insert a toothpick into the center. If it comes out clean and the center isn’t jiggly, your cake is ready!
- Once baked, remove the cake from the oven and let it rest in the pan for a few minutes before transferring it to a wire cooling rack. This step is important as it stops the cooking process and prevents the cake from becoming too dense.
- Allow the cake to cool completely before applying any icing. This is crucial; applying icing on a warm cake can cause it to melt and slide off, ruining the beautiful presentation.
- Once cooled, you can frost the cake with your favorite frosting. Enjoy the delightful taste of your freshly baked Peanut Butter Cake!
Things Worth Knowing
- Use room temperature ingredients: Make sure to use room temperature eggs and butter for a smoother batter. This helps in achieving a better texture.
- Mixing technique matters: When combining ingredients, don’t overmix. Stop mixing as soon as you see the batter is smooth, as overmixing can lead to a denser cake.
- Cooling is crucial: Allow the cake to cool completely before frosting. This ensures the frosting stays intact and looks beautiful on your finished cake.
- Storage tips: Keep any leftovers in an airtight container at room temperature for up to three days, or refrigerate for longer freshness.
Making Adjustments

Here are some helpful tips to consider when making your Peanut Butter Cake to ensure it’s perfect every time!
- Storage: After the cake has cooled and is frosted, store it in an airtight container at room temperature for up to three days. If you have leftovers, it can also be refrigerated for added freshness.
- Freezing: You can freeze the cake before frosting. Wrap it tightly in plastic wrap and then in aluminum foil, and it will keep well for up to three months. Just thaw it in the fridge before frosting!
- Pairing: This cake pairs beautifully with a glass of milk or a cup of coffee, making it a perfect treat for an afternoon snack.
- Celebration cake: Consider decorating it with chocolate chips or sprinkles for a festive touch at celebrations.
- Adjust sweetness: If you prefer a less sweet cake, you can slightly reduce the butter and sugar in the frosting.
Accompaniments for Peanut Butter Cake
Serving your Peanut Butter Cake can elevate the experience even further! Here are some delightful ideas:
- Ice Cream: Serve slices of this cake warm with a scoop of vanilla ice cream for a decadent treat.
- Fresh Berries: Pair it with fresh strawberries or raspberries for a fruity contrast that balances the sweetness.
- Whipped Cream: A dollop of homemade whipped cream adds a light and airy element to the rich cake.
- Coffee or Tea: Enjoy the cake with a cup of hot coffee or tea; the warmth enhances the flavors of the peanut butter.
- Celebrations: This cake is perfect for birthdays, holidays, or any festive occasion, making it a go-to dessert for gatherings.
