A little history behind peanut butter muffins

Ingredient insights and tweaks
- Peanut Butter: I prefer creamy for smooth texture, but crunchy adds delightful crunch. Swap with almond butter for a different nutty flavor.
- Flour: Whole wheat adds nuttiness and fiber, but all-purpose keeps it lighter and softer.
- Sugar: Brown sugar gives a molasses note, white sugar keeps it sweet and straightforward.
- Eggs: Bind everything together, but flax eggs work if you’re vegan.
- Milk: Adds moisture, almond or oat milk can be a dairy-free alternative.
Spotlight on Peanut Butter and Flour
Peanut Butter:
- The oozy, oily richness is the star—choose natural for the purest flavor.
- It melts into the batter, giving a delightful swirl of peanut aroma with every bite.
- It can seize up if overmixed, so fold gently to keep the texture smooth.
Flour:
- The base that gives structure—whole wheat adds a nutty flavor, all-purpose keeps it tender.
- It absorbs moisture, so measure carefully to avoid dense muffins.
- Sifts help prevent lumps and ensure a light crumb.
Ingredient substitutions for different diets and flavors
- Dairy-Free: Swap regular milk with almond or oat milk for a nutty, creamy twist.
- Sweetener: Use honey or maple syrup instead of sugar for a floral note.
- Gluten-Free: Replace wheat flour with a gluten-free blend, but expect a slightly denser crumb.
- Add-ins: Chocolate chips or chopped nuts can replace or accompany any mix-ins.
- Fat: Replace oil with applesauce for a lighter, fruity note.
Equipment & Tools
- Muffin tin: To hold the batter and shape the muffins.
- Mixing bowls: To combine ingredients.
- Whisk or spoon: To mix ingredients evenly.
- Cooling rack: To cool muffins evenly.
Step-by-step guide to perfect peanut butter muffins
- Preheat your oven to 180°C (350°F). Line a muffin tin with paper liners or grease it well.
- In a large bowl, whisk together 1 cup of flour, 1/2 cup of sugar, and 1 tsp baking powder.
- Add 1/2 cup of creamy peanut butter, 1/2 cup of milk, 1/4 cup of vegetable oil, and 2 eggs to the dry ingredients.
- Mix everything until just combined—don’t overmix or muffins might get dense.
- Divide the batter evenly among the muffin cups, filling each about 3/4 full.
- Bake for 20-22 minutes. The tops should turn a light golden, and a toothpick inserted in the center comes out clean.
- Remove from oven and let sit for 5 minutes. Transfer to a wire rack to cool completely.
- Optional: sprinkle with sea salt or drizzle honey while still warm for extra flavor.
Let the muffins cool for at least 10 minutes before eating or storing. Serve warm or at room temperature.
How to Know It’s Done
- Golden brown tops, not burnt.
- Toothpick comes out clean.

Ingredients
Equipment
Method
- Preheat your oven to 180°C (350°F). Lightly grease your muffin tin or line it with paper liners to prevent sticking.
- In a large mixing bowl, whisk together the flour, sugar, and baking powder until evenly combined. This creates a fluffy, uniform base for your muffins.
- Add the creamy peanut butter to the bowl and stir it into the dry mixture until it looks slightly streaked but still crumbly.
- Pour in the milk and vegetable oil, then crack in the eggs. Use a whisk or spoon to gently fold all the ingredients together until just combined—don’t overmix, or the muffins may turn dense.
- Once the batter looks thick but smooth, divide it evenly among the muffin cups, filling each about three-quarters full—use a spoon or scoop for clean, even portions.
- Bake in the preheated oven for 20 to 22 minutes, or until the tops turn a light golden brown and a toothpick inserted in the center comes out clean. You’ll hear a gentle sizzle as the muffins bake and see their edges firming up.
- Remove the muffins from the oven and let them rest in the tin for about 5 minutes. Then, transfer them to a wire rack to cool completely—this prevents sogginess and allows the aroma to fully develop.
- Once cooled, serve the muffins warm or at room temperature. For an extra touch, sprinkle a pinch of sea salt on top or drizzle with honey while they’re still warm for added flavor.
Cooking tips and tricks for perfect muffins
- BOLDEN THE TOP: Brush with a bit of egg wash for a shiny finish.
- MOISTURE CONTROL: Don’t overmix—just stir until ingredients are combined.
- TEXTURE TIP: Fold in chopped nuts or chocolate chips for variety.
- BAKING HEAT: Use the middle rack for even baking.
- FLAVOR BOOST: Add a pinch of cinnamon or a splash of vanilla for depth.
Common mistakes and how to fix them
- FORGOT TO PREHEAT THE OVEN? Heat it now and bake a few extra minutes.
- DUMPED TOO MUCH FLOUR? Add a splash of milk until batter is just right.
- OVER-TORCHED THE TOP? Cover with foil and lower the oven temp.
- BATTER WAS TOO RUNNY? Add a little more flour, a pinch at a time.
Quick fixes to rescue your muffins
- When batter is too thick, splash in a little milk and stir gently.
- If muffins crack top, reduce oven temperature slightly.
- Patch dry muffins by brushing with a syrup or honey.
- Splash a few drops of lemon juice into batter if it’s too bland.

- Baked muffins stay good in an airtight container for 2 days at room temp or up to a week refrigerated.
- Reheat in microwave for 10-15 seconds until warm and fragrant.
- Add a smear of butter or a drizzle of honey before serving for extra richness.
