The Surprising History of Peanut Butter in Baking
- Peanut butter muffins are a favorite in many home kitchens, especially in the States, dating back to mid-20th century home baking.
- The combination of peanut butter and baking soda creates a quick rise, making these muffins fluffy inside.
- Peanut butter in baking was popularized during the wartime era when ingredients needed to be versatile and filling.
- Adding a sprinkle of sea salt on top before baking enhances the flavor and adds a nice crunch.
Ingredient Traits & Tweak Tips
- Peanut Butter: I prefer creamy for a smooth crumb, but crunchy adds texture. The smell of toasted peanuts is irresistible.
- Eggs: They bind everything together and add moisture. Use fresh eggs for best rise and flavor.
- Flour: All-purpose gives structure. Swap with gluten-free if needed, but expect a different crumb.
- Sugar: Sweetens and tenderizes. Brown sugar adds moisture and a caramel note.
- Baking soda: It reacts with peanut butter’s natural oils for a quick rise. For a tangy flavor, add a splash of vinegar.
- Vanilla extract: Enhances sweetness and depth. Skip if you want a more straightforward peanut flavor.
- Salt: Balances sweetness and highlights the peanutty aroma. Use sea salt for crunch on top.
Spotlight on Peanut Butter & Eggs
Peanut Butter:
- It’s naturally oily, so the batter will be thick and sticky. Toasted peanut flavor is richer.
- It melts into the batter, creating a chewy, dense crumb with bursts of nutty flavor.
Eggs:
- They add richness and help the muffins rise. Fresh eggs give a more vibrant yellow crumb.
- Room temperature eggs blend better, giving the batter a smooth, silky texture.
Ingredient Substitutions
- Dairy-Free: Substitute with almond or coconut butter for similar richness, but expect a slightly different flavor.
- Sugar: Use honey or maple syrup for a different sweetness profile. Reduce the liquid slightly.
- Flour: Swap with oat flour or gluten-free blend, but muffins may be more crumbly.
- Eggs: Use unsweetened applesauce or mashed banana for binding, though texture may change.
- Baking soda: Use baking powder if necessary, but adjust quantities for rise.
- Vanilla: Skip for a more straightforward peanut flavor, or add a splash of almond extract.
Equipment & Tools
- Mixing bowls: Combine wet and dry ingredients.
- Whisk or spoon: Stir ingredients smoothly.
- Muffin tin and liners: Shape and bake the muffins.
- Cooling rack: Cool muffins evenly and prevent sogginess.
Step-by-step for Perfect Peanut Butter Muffins
- Preheat your oven to 180°C (350°F). Grease a muffin tin or line it with paper liners.
- Mix 1 cup of peanut butter, 1 cup of sugar, 2 eggs, and 1 teaspoon of vanilla until smooth. The batter will be thick and sticky.
- In a separate bowl, whisk together 1 1/2 cups of all-purpose flour, 1 teaspoon of baking soda, and a pinch of salt.
- Gradually fold the dry ingredients into the wet, just until combined. Don’t overmix—lumps are fine.
- Divide the batter evenly into the muffin cups—about 3/4 full each. They’ll be quite dense.
- Bake for 20-25 minutes. Check at 20; the tops should be golden, and a toothpick inserted in the center should come out clean.
- Remove from oven and let cool in the tin for 10 minutes. Transfer to a wire rack or plate.
- Let the muffins rest for at least 10 minutes before serving. They’ll firm up slightly and smell amazing.
Cool in the tin for 10 minutes, then transfer to a wire rack. Serve warm or at room temperature.
How to Know It’s Done
- Muffins are golden on top and slightly cracked.
- Toothpick test: comes out clean when inserted in the middle.
- Edges gently pull away from the pan, indicating they’re baked through.

Method
- Preheat your oven to 180°C (350°F), and line a muffin tin with paper liners or lightly grease it.
- In a large mixing bowl, combine the peanut butter and sugar with a whisk or spoon until the mixture is smooth and slightly fluffy, releasing a warm, nutty aroma.
- Add the eggs one at a time, whisking well after each addition until the batter is thick, glossy, and cohesive.
- Stir in the vanilla extract, if using, to deepen the flavor and add a sweet aroma.
- In a separate bowl, whisk together the flour, baking soda, and salt to evenly distribute the leavening and seasoning.
- Gradually fold the dry ingredients into the wet mixture with a spatula or spoon, just until combined. The batter will be thick, lumpy, and sticky, with bits of peanut visible.
- Spoon the batter evenly into the prepared muffin cups, filling about three-quarters full. The batter should mound slightly above the rim, with a textured surface.
- Bake in the preheated oven for 20-25 minutes, or until the tops are golden brown and a toothpick inserted into the center comes out clean. You’ll smell warm peanut and vanilla notes filling the kitchen.
- Remove the muffins from the oven and let them cool in the tin for about 10 minutes, until they feel firm and release easily from the liners or pan.
- Transfer the muffins to a wire rack to cool completely or enjoy warm—either way, the texture should be soft and moist with gooey peanut bits in every bite.
- Serve these cozy muffins fresh for maximum flavor and aroma, or store in an airtight container for up to a day or freeze for longer storage.
