Peanut Butter Banana Greek Yogurt Muffins (No Butter, No Oil)
Three spotty bananas and a jar of peanut butter turn into a dozen soft, protein-packed muffins for pennies each. These peanut butter banana muffins use Greek yogurt instead of butter or oil, so every bite stays moist while quietly adding protein.
The ingredients are pantry staples you probably already have, which makes this one of the cheapest ways to use up bananas before they go to waste. Bananas bring natural sweetness, so you need less added sugar.
Peanut butter and Greek yogurt do the heavy lifting on protein and richness. No fancy equipment, no expensive add-ins, just one bowl and a fork.
Why You’ll Love This Recipe
- Cheap and pantry-friendly. Flour, sugar, eggs, bananas, peanut butter, and yogurt. Nothing on this list breaks the budget.
- Higher protein than a normal muffin. Greek yogurt and peanut butter push the protein up so these actually hold you over.
- No butter and no oil. The bananas and yogurt keep them tender, so you skip the extra fat and cost.
- Zero waste win. This is the perfect home for bananas that are too soft to eat plain.
Fabian’s Budget & Health Tip: Buy bananas that are already heavily speckled or marked down on the “reduced” shelf. They are usually a fraction of the price and far sweeter, which means you can cut the added sugar to a scant 1/3 cup and the muffins still taste great. Freeze any extra ripe bananas in their skins so you always have a cheap batch ready to go.
Ingredients (Makes 12 Muffins)
Wet ingredients:
- 3 ripe bananas (about 1 1/2 cups / 360 g mashed)
- 1/2 cup peanut butter (128 g)
- 1/2 cup Greek yogurt (120 g)
- 2 large eggs
- 1 tsp vanilla extract (5 ml)
- 1/2 cup sugar (100 g)
Dry ingredients:
- 1 3/4 cups all-purpose flour (220 g)
- 1 tsp baking soda (5 g)
- 1/4 tsp salt (optional, 1 g)
Step-by-Step Instructions
🔥 Step 1: Heat the Oven and Prep the Tin
Set your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or give it a light grease. Let the oven fully preheat while you mix, so the tops dome up nicely the moment they go in.
🍌 Step 2: Mash the Bananas
Drop the bananas into a large bowl. Mash with a fork until they turn into a smooth, slightly stringy puree with just a few small lumps left. The riper and browner they are, the easier they break down. You will smell that sweet, almost candy-like banana aroma the second you start. That is exactly what you want.
🥜 Step 3: Whisk in the Wet Ingredients
Add the peanut butter, Greek yogurt, eggs, vanilla, and sugar to the mashed banana. Whisk hard for about a minute. The mixture goes from streaky and pale to glossy and uniform once the peanut butter fully blends in. When you lift the whisk, the batter should ribbon off in a smooth, thick stream.
🥣 Step 4: Whisk the Dry Ingredients Separately
In a second bowl, whisk together the flour, baking soda, and salt. Give it a good 10 seconds so the baking soda spreads evenly. Listen for the soft scratch of the whisk against the bowl. No clumps should remain.
🌀 Step 5: Fold Wet and Dry Together
Tip the dry mix into the wet. Fold gently with a spatula, scraping the bottom of the bowl, just until the last dry streak disappears. Stop the moment it looks combined. The batter should be thick and scoopable, dropping off the spoon in slow, heavy ribbons. Overmixing here makes tough, gummy muffins, so resist the urge to keep stirring.
🥄 Step 6: Fill the Muffin Cups
Spoon the batter evenly into the 12 cups, filling each about three-quarters full. A cookie scoop keeps them tidy and even. Tap the tin gently on the counter once to settle the batter.
⏲️ Step 7: Bake Until Golden and Domed
Bake for 20 to 22 minutes. Watch for the tops to dome and turn a deep golden brown around the edges. Around the 18-minute mark your whole kitchen should smell like warm banana bread with a nutty edge. Slide a toothpick into the center of one. It should come out clean or with a few dry crumbs, never wet batter.
🧊 Step 8: Cool Before Eating
Let the muffins rest in the tin for 5 minutes. They firm up as they cool. Then lift them onto a wire rack so the bottoms do not steam and go soggy. The tops should spring back lightly when you press them.
Expert Troubleshooting & FAQs
Why are my muffins dense or gummy?
This almost always comes from overmixing. Once the flour goes in, fold just until you no longer see dry streaks. The batter should look a little lumpy, not smooth. A few stirs too many develops the gluten and turns soft muffins heavy.
What if my batter looks too thick to scoop?
That is normal for this recipe, since there is no oil. If it feels truly stiff and hard to spread, stir in 1 to 2 tablespoons of extra Greek yogurt or a splash of milk. Add it slowly. You want a thick, droppable batter, not a pourable one.
Can I use natural peanut butter?
Yes, but stir the jar well first so the oil is fully mixed back in. Natural peanut butter is looser, so your batter may be slightly softer. The muffins still bake up fine. Avoid the dry, separated layer at the bottom of an unstirred jar.
