The Curious Roots of Peanut Butter Baking

• This recipe is inspired by childhood memories of peanut butter and banana snacks.

Ingredient Insights

• Peanut Butter: I use natural, chunky for texture, but smooth works too. The gooey, nutty aroma is irresistible.
• Eggs: They bind everything together and add richness. Use flaxseed meal for a vegan twist, but expect a slightly denser crumb.
• Flour: All-purpose gives the right structure. Whole wheat adds fiber and a nutty flavor, but might make muffins denser.
• Sugar: I prefer brown sugar for a richer taste, but honey or maple syrup can work for a different sweetness profile.
• Baking soda: The leavening hero that helps muffins rise. Baking powder can be a substitute, but results vary slightly.

Spotlight on Peanut Butter and Eggs

Peanut Butter:

• The natural oils in peanut butter can separate; stir well before using to ensure even flavor.
• It becomes gooey and fragrant when warmed, helping it blend smoothly into batter.
• Chunky peanut butter adds delightful texture; smooth makes for a velvety crumb.

Eggs:

• Eggs lend structure and moisture. Room temperature eggs blend more easily, avoiding lumps.
• They puff up slightly in the oven, giving muffins a tender crumb.
• Overbeating eggs can create tunnels; mix just until combined.

Substitution Tips for Different Needs

• Dairy-Free: Swap butter for coconut oil for a subtle coconut aroma.
• Gluten-Free: Use a 1:1 gluten-free flour blend, but expect a slightly denser crumb.
• Sweetener: Replace sugar with mashed bananas or applesauce for less sweetness.
• Nut-Free: Use sunflower seed butter instead of peanut butter.
• Vegan: Use flaxseed or chia seed gel instead of eggs for binding.

Equipment & Tools

• Mixing bowls: Combine ingredients comfortably and thoroughly.
• Whisk and spatula: Mix and fold ingredients evenly.
• Muffin tin and liners: Shape muffins and prevent sticking.
• Cooling rack: Allow muffins to cool evenly and prevent sogginess.

Step-by-Step Guide to Perfect Peanut Butter Muffins

1. Preheat your oven to 180°C (350°F). Line a muffin tin with paper liners.
2. In a large bowl, mix 1 cup (240g) peanut butter, 1/2 cup (100g) sugar, and 2 eggs. Whisk until smooth.
3. In another bowl, whisk together 1 1/2 cups (190g) all-purpose flour, 1 teaspoon baking soda, and a pinch of salt.
4. Gradually add dry ingredients to wet, folding gently until just combined. Do not overmix.
5. Scoop batter into muffin tins, filling about 3/4 full. Bake for 15–18 minutes, until golden and a toothpick comes out clean.
6. Let muffins cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.

Allow muffins to rest for at least 10 minutes before serving to set the crumb and enhance flavor.

How to Know It’s Done

Tips & Tricks for Perfect Muffins
