Trivia and Origins
- Peanut butter muffins gained popularity in early American home baking, blending pantry staples into quick treats.

Ingredient breakdown
- Peanut Butter: I use creamy, natural peanut butter for a rich, oozing flavor that keeps the muffins moist. Swap with almond or cashew butter if you want a different nutty note, but expect a slightly different texture.
- Flour: I stick with all-purpose flour for structure, but you can try whole wheat for a heartier crumb. Just expect a denser muffin with a deeper, nutty aroma.
- Sugar: I prefer brown sugar for a subtle caramel undertone that enhances the nutty flavor. You could swap with coconut sugar for a hint of earthiness, though it may change the moisture.
- Eggs: They help bind everything together and keep the muffins fluffy. If you’re vegan, applesauce or mashed banana work, but may make the muffins a bit denser.
- Baking Powder: I always ensure it’s fresh for a good rise. If it’s old, the muffins might not puff up properly, so do a quick test first.
- Milk: I use whole milk for richness, but almond or oat milk can be good dairy-free options, adding a slight nutty or creamy note, depending on the milk.
- Vanilla Extract: A splash enhances sweetness and depth. Skip if you want a more straightforward nutty hit, but don’t skip altogether; it rounds out the flavors nicely.

Notes for ingredient swaps
- Dairy-Free: Swap cow’s milk for almond, oat, or soy milk. It keeps the batter moist, but expect a slightly nuttier or creamier taste depending on the milk. Skipping dairy won’t affect the rise much.
- Nut Butters: Use almond or cashew butter instead of peanut. They add different nutty nuances but can change the flavor profile slightly. Creamy versions work best for smooth muffins.
- Sweetener: Replace brown sugar with coconut sugar or honey. Coconut sugar offers a caramel note, while honey adds moisture and a floral touch. Adjust quantities to taste to avoid overly sweet muffins.
- Flour: Whole wheat or spelt flour can replace all-purpose flour for a denser, heartier crumb. Expect a nuttier flavor and slightly more compact muffins. Sift if you want a lighter texture.
- Eggs: For vegan options, substitute with applesauce or mashed banana. These will make the muffins a touch denser and add a subtle fruit flavor, but they help keep the muffins moist.
- Add-ins: Chocolate chips or chopped nuts can be omitted or swapped with dried fruit or shredded coconut for different textures and flavor surprises. Keep in mind they may affect baking time slightly.
- Baking Powder: Ensure it’s fresh for proper rise. If you notice flat muffins, double-check your baking powder’s potency or try adding a pinch more for extra lift.
Equipment & Tools
- Muffin tin: Holds the batter during baking for even shape.
- Mixing bowls: Combine ingredients separately and then mix together.
- Whisk or spoon: Blend wet ingredients smoothly.
- Measuring cups/spoons: Ensure accurate ingredient portions.
- Cooling rack: Allow muffins to cool evenly, preventing sogginess.
Step-by-step guide to peanut butter muffins
- Preheat your oven to 180°C (350°F). Line a muffin tin with paper liners or grease it well. Have your ingredients ready and measured.
- In a large bowl, mix 1 cup (120g) all-purpose flour, 1/2 cup (100g) brown sugar, and 1 teaspoon baking powder. Stir to combine.
- In a separate bowl, whisk together 1 large egg, 1/2 cup (125ml) milk, 1/4 cup (65g) melted butter or oil, and 1/2 cup (125g) creamy peanut butter. Mix until smooth.
- Pour the wet ingredients into the dry. Gently fold together until just combined—don’t overmix; some lumps are okay.
- If using add-ins (chocolate chips, chopped nuts), fold in now. They add texture and fun surprises.
- Spoon the batter into the prepared muffin tin—about 2/3 full. Smooth the tops with the back of a spoon.
- Bake for 18-20 minutes. The muffins should turn golden and a toothpick inserted in the center comes out clean.
- Check for doneness: the tops should be slightly cracked, smell toasted and nutty, and the edges golden.
- Remove from oven. Let the muffins rest in the tin for 5 minutes, then transfer to a wire rack to cool slightly.
- Finish with a light drizzle of honey or a sprinkle of sea salt if desired. Serve warm or at room temperature.

Method
- Preheat your oven to 180°C (350°F) and line a muffin tin with paper liners or grease it well.
- In a large mixing bowl, whisk together the flour, brown sugar, and baking powder until evenly combined. This helps distribute the leavening agents for a good rise.
- In a separate bowl, beat the egg, then stir in the milk, melted butter, and creamy peanut butter until the mixture is smooth and slightly frothy. This creates a rich, cohesive wet base.
- Pour the wet mixture into the bowl of dry ingredients, gently folding together with a spoon or whisk. Mix until just combined; avoid overmixing to keep the muffins tender.
- Spoon the batter into the prepared muffin cups, filling each about two-thirds full. Use the back of the spoon to smooth the tops and create an even surface.
- If desired, add a small dollop of peanut butter in the center of each muffin for gooey pockets, or swirl gently with a toothpick.
- Bake in the preheated oven for 18-20 minutes, until the muffins are golden and cracked on top, and a toothpick inserted into the center comes out clean.
- Once baked, remove the muffins from the oven and let them cool in the tin for about 5 minutes. Then transfer them to a wire rack to cool slightly, which prevents sogginess.
- If desired, drizzle with honey or sprinkle with sea salt for extra flavor. Serve warm or at room temperature for best taste.
Pro tips for perfect peanut butter muffins
- Bold the surface: Lightly sprinkle the muffin tops with sugar before baking to create a crackly, sweet crust.
- Room temperature ingredients: Ensure eggs and butter are soft for smoother mixing and better rise.
- Don’t overmix: Gently fold the batter until just combined to keep muffins light and fluffy.
- Use an ice cream scoop: For even-sized muffins, which bake uniformly and look tidy.
- Check oven temperature: Use an oven thermometer to avoid under- or over-baking, ensuring golden color and proper rise.
- Add a swirl: Drop a spoonful of peanut butter into the center of each muffin before baking for gooey pockets.
- Rest the batter: Let it sit for 5 minutes after mixing to allow the flour to hydrate, resulting in tender muffins.
Common mistakes and how to fix them
- FORGOT to check oven temperature → Preheat thoroughly before baking.
- DUMPED in all ingredients at once → Mix dry and wet separately first.
- OVER-TORCHED the muffins → Bake at 180°C (350°F) and watch for golden tops.
- UNDERSCORED the batter → Fill muffin cups 2/3 full for even rise.
Quick Fixes and Pantry Swaps
- If batter seems too thick, splash in a teaspoon of milk and stir gently.
- When muffins crack excessively, shield tops with foil halfway through baking.
- Splash a few drops of water on the oven floor if muffins over-torched and crackle.
- Dumped in too much baking powder? Add a tablespoon of flour to balance rise.
- When muffins are flat, rescue with a quick 5-minute rest in the oven at 150°C (300°F).
Prep, store, and reheat tips
- Prepare the dry ingredients—measure and mix the flour, sugar, and baking powder—up to a day in advance. Keep in an airtight container; the dry mix stays fresh and ready to go.
- Assemble wet ingredients and portion the batter into muffin cups. Cover tightly with plastic wrap and refrigerate for up to 24 hours. The batter thickens slightly overnight, but still bakes up moist and tender.
- Store baked muffins in an airtight container at room temperature for 1-2 days. They maintain moisture, but the peanut butter flavor intensifies over time, making each bite richer.
- For longer storage, freeze muffins in a sealed bag for up to 3 months. To reheat, wrap in a damp paper towel and microwave for 15–20 seconds. The smell of warm peanut butter will fill your kitchen, and the muffins will be soft and gooey inside.
