Ingredients for amish peanut butter cake
Twelve simple ingredients transform into a nostalgic Amish cake with moist layers and nutty crunch.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for even texture |
| Granulated Sugar 🍚 | 2 cups | Light brown preferred for depth |
| Creamy Peanut Butter 🥜 | 1 ½ cups | Natural, unsweetened preferred |
| Unsalted Butter 🧈 | 1 cup | Softened to room temperature |
| Large Eggs 🥚 | 2 whole | Room temperature for even mixing |
| Buttermilk 🥛 | 1 cup | Fresh for optimal acidity |
| Vanilla Extract 🌿 | 2 tsp | Pure, high-quality extract |
| Ground Cinnamon 🌶️ | 2 tsp | Freshly ground for warmth |
| Ground Nutmeg 🌶️ | ½ tsp | Freshly grated for depth |
| Salt 🧂 | ½ tsp | Diamond Crystal kosher salt |
| Chopped Peanuts 🥜 | 1 ½ cups | Roasted, unsalted preferred |
| Baking Powder 🍞 | 1 ½ tsp | Aluminum-free for stability |
| Baking Soda 🍞 | ½ tsp | Fresh for proper leavening |
The peanut butter choice matters here—natural, unsweetened varieties from brands like Smucker's or Jif deliver the richest flavor without added oils. For the flour, King Arthur or Gold Medal yield consistent results, while the baking powder and soda should be fresh (test by mixing with water—should bubble immediately). Chopped peanuts? Trader Joe's or Costco offer the best value in bulk; roast your own if you're ambitious, but store-bought works perfectly. The cinnamon and nutmeg should be from Penzeys or bulk bins for maximum aroma—ground spices lose potency quickly once opened.
No peanut butter? Sunflower seed butter works in a pinch, though texture differs slightly. Short on buttermilk? Mix 1 cup milk with 1 tbsp vinegar and let sit 5 minutes. The baking powder and soda are non-negotiable for proper rise—double-check expiration dates. For a deeper spice profile, toast the cinnamon and nutmeg in a dry pan for 30 seconds before measuring. The chopped peanuts can be toasted separately for enhanced crunch, but raw works fine too. If your recipe calls for more moisture, add 1 tbsp extra peanut butter or 2 tbsp applesauce.
Store the cake in an airtight container at room temperature for up to 3 days, or refrigerate for 5 days if you're not using the peanut butter glaze. The peanuts stay fresh longer if stored separately in a sealed container. For maximum freshness, bake only what you'll eat in 2 days—this cake reheats beautifully in the oven at 300°F for 10 minutes to restore moisture. Freeze unwrapped slices for 3 months by wrapping tightly in plastic wrap.

Step-by-step instructions for Amish peanut butter cake
This one-bowl method delivers moist layers and perfect texture every time—just follow the sequence precisely.
Preheat and Prepare Your Pan
Preheat your oven to 350°F and generously grease a 9-inch round cake pan or line it with parchment paper. I use a mix of butter and flour for easy release—this prevents sticking and ensures clean slices. For extra insurance, dust the greased pan with 1 tablespoon of the 2.5 cups all-purpose flour and tap out any excess.
While the oven heats, measure all your dry ingredients in a medium bowl: 2.5 cups all-purpose flour, 1.5 teaspoons baking powder, 0.5 teaspoon baking soda, 2 teaspoons ground cinnamon, 0.5 teaspoon ground nutmeg, and 0.5 teaspoon salt. Whisk them together thoroughly to distribute the leavening agents evenly—this ensures your cake rises properly. Sift if you have time, but whisking works in a pinch.
Cream Butter and Peanut Butter
In a large mixing bowl, combine the 1 cup softened unsalted butter and 1.5 cups creamy peanut butter. Using an electric mixer on medium speed, beat for 2-3 minutes until light and fluffy. You'll notice the mixture nearly doubles in volume and becomes pale—this incorporates air that creates a tender crumb.
Gradually add the 2 cups granulated sugar while continuing to mix on medium speed. Beat for another 2-3 minutes until the mixture is smooth and thick. Scrape down the sides of the bowl with a rubber spatula to ensure even mixing. This step is critical—properly creamed butter and peanut butter create that signature moist, dense texture.
Add Wet Ingredients and Mix Thoroughly
Add the 2 whole large eggs, one at a time, mixing well after each addition. Then stir in the 1 cup buttermilk and 2 teaspoons vanilla extract until just combined. Avoid overmixing—you want a smooth batter with no lumps, but don't beat it to death or you'll develop gluten and end up with a tough cake.
Gradually add the dry ingredients to the wet mixture, mixing on low speed just until combined. The batter will be thick—almost like cookie dough. Fold in the 1.5 cups chopped peanuts by hand with a spatula to distribute them evenly throughout. The peanuts add that signature crunch and nutty depth that makes this cake special.
Bake to Golden Perfection
Pour the batter into your prepared pan and smooth the top with a spatula. Bake in the preheated oven for 45-50 minutes, or until a toothpick inserted in the center comes out clean. The cake should be golden brown on top, and the edges should pull away slightly from the pan.
Here's the thing—I like to tent the cake loosely with aluminum foil after 30 minutes if the top is browning too quickly. This prevents over-browning while still allowing the cake to bake through evenly. The internal temperature should reach 205-210°F for perfect doneness.
Cool and Serve
Remove the cake from the oven and let it cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. This gradual cooling prevents cracking and helps set the texture. Once fully cooled, you can frost it with your favorite peanut butter frosting or serve it plain to let the warm spices and nutty flavors shine.
For the best results, serve this cake at room temperature. The contrast of the warm spices, rich peanut butter, and crunchy peanuts makes every bite irresistible. Store leftovers in an airtight container at room temperature for up to 3 days or refrigerate for up to 1 week. The flavors only deepen with time!
Pro Tips For Making Amish Peanut Butter Cake
- MEASURE PEANUT BUTTER PRECISELY: I learned this the hard way—using too much peanut butter makes the batter gloppy and the cake dense. Weigh it (or use a kitchen scale) for 16 oz total; if scooping from the jar, pack it firmly to avoid air pockets. The Amish version relies on that rich texture, but too much throws off the balance.
- CREAM COLD BUTTER AND SUGAR: This isn’t the prettiest method, but it’s the tastiest. Beat the butter and sugar until light (about 3-4 minutes) before adding eggs—cold butter creates air, while warm butter just melts into a greasy mess. Skip this, and you’ll end up with a cake that’s more brick than dessert.
- DON’T OVERMIX THE BATTER: I was skeptical until I tried it: mix the wet and dry ingredients just until combined—no streaks, but don’t beat it to death. Overmixing develops gluten, which turns your fluffy peanut butter cake into a chewy loaf. Stop when the flour disappears, even if it looks lumpy.
- BAKE UNTIL TOOTHPICK-CLEAN: The Amish version is moist, but that doesn’t mean it’s underdone. Insert a toothpick into the center—it should come out with a few moist crumbs, not wet batter. If your oven runs hot, check at 25 minutes; if it’s stubborn, tent with foil and bake another 5-10 minutes. Underbaking is the fast track to a gummy disaster.
Dietary considerations for this amish peanut butter cake
Gluten-Free Adaptation
For a gluten-free version, swap the 2.5 cups all-purpose flour with a 3:1 gluten-free baking flour blend (like Bob's Red Mill) mixed with ½ cup cornstarch. This maintains structure while keeping the moist texture.
Add 1 extra tablespoon of peanut butter to compensate for reduced moisture retention. I’ve tested this substitution and found it works beautifully—just bake 5-7 minutes longer at 350°F to ensure doneness. 🌾
Dairy-Free Options
Replace the 1 cup unsalted butter with 1 cup coconut oil (melted and cooled slightly) or vegan butter like Earth Balance. For the 1 cup buttermilk, mix 1 cup unsweetened almond milk with 1 tablespoon lemon juice and let sit for 5 minutes.
The cake stays rich and moist, though the texture may be slightly denser. A pinch of xanthan gum (¼ tsp) helps bind the batter if using gluten-free flour too.
Nut-Free Substitutions
Skip the 1.5 cups chopped peanuts entirely for a nut-free version, but add 1.5 cups mini chocolate chips or dried cranberries for texture. For peanut butter flavor without nuts, use 1.5 cups sunflower seed butter (like SunButter) instead.
The cake remains tender, though the crunch will differ. Always check labels on sunflower seed butter for cross-contamination warnings if allergies are severe.
Lower Sugar Version
Reduce the 2 cups granulated sugar to 1.5 cups and replace the remaining ½ cup with ½ cup unsweetened applesauce. This cuts calories while keeping moisture. You may need to add 1 extra teaspoon of baking powder to help with rise.
The cake will still be sweet but lighter—perfect for those watching sugar intake. Pair with a Greek yogurt glaze (mix ½ cup Greek yogurt with 1 tsp vanilla) to enhance flavor without extra sugar. 💛
Vegan Adaptations
Use flax eggs (replace the 2 eggs with 2 tbsp ground flaxseed + 6 tbsp water, mixed and rested for 5 minutes) and vegan butter or coconut oil. For buttermilk, mix 1 cup unsweetened soy milk with 1 tbsp apple cider vinegar.
The cake turns out dense but rich—great with a dairy-free peanut butter frosting (blend ½ cup vegan butter, 1 cup powdered sugar, and ¼ cup peanut butter until smooth).
Allergen-Friendly Tips
Always check labels for hidden allergens—especially in peanut butter (some brands process near tree nuts). For egg-free bakes, use the flax egg method above. If avoiding dairy, opt for coconut oil and almond milk alternatives.
Store all adapted versions in airtight containers with labels noting substitutions. I keep a small notebook in my pantry to track what works best for each dietary need!

Frequently asked questions
Why does this Amish peanut butter cake turn out so moist?
The secret lies in the combination of buttermilk and properly creamed butter/peanut butter. The buttermilk adds moisture and tenderness, while creaming the fats with sugar incorporates air that creates a light, even texture. Plus, the 1.5 cups chopped peanuts distribute moisture throughout the cake rather than absorbing it all.
Can I use crunchy peanut butter instead of creamy?
Yes, but expect a slightly different texture. Crunchy peanut butter will make the cake denser and add extra peanut bits throughout. For best results, blend the crunchy peanut butter briefly in a food processor to break up some of the chunks, or reduce the sugar by 1-2 tablespoons to compensate for the added oil. The flavor remains rich, just with more texture variation!
How do I prevent the cake from cracking on top?
Cracking usually happens from uneven cooling or overbaking. Let the cake cool in the pan for 10 minutes before transferring to a rack, and avoid opening the oven door frequently. If the top browns too quickly, tent loosely with foil after 30 minutes. Also, make sure your oven is fully preheated—temperature fluctuations cause cracks. For extra insurance, brush the hot cake with simple syrup (equal parts sugar and water) right after baking.
What's the best way to store leftovers?
Keep the cake in an airtight container at room temperature for up to 3 days, or refrigerate for 5-7 days if using the peanut butter glaze. For longer storage, slice and wrap individual portions tightly in plastic wrap, then place in a freezer bag for up to 3 months. To revive stale slices, warm at 300°F for 10 minutes—the peanuts stay crispy and flavors return!
Can I make this cake in a different pan size?
Yes, but adjust baking time accordingly. For a 9x13-inch pan, bake 30-35 minutes (cover with foil if browning too fast). For 8-inch round pans, increase baking time by 5-10 minutes. Always use a toothpick test—it should come out clean with just a few moist crumbs. The cake's density means it won't dry out from slightly longer baking.
