Step‑by‑Step Instructions for Healthy Greek Yogurt Peanut Butter Banana Oat Blondie Muffins with Gooey Tops
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). While the oven warms up, prepare a muffin pan by lining it with muffin liners or lightly greasing each cup with cooking spray. This ensures your Healthy Greek Yogurt Peanut Butter Banana Oat Blondie Muffins release easily after baking.
Step 2: Mash the Bananas
In a large mixing bowl, take the ripe bananas and mash them with a fork until they are smooth and creamy. Aim for a puree-like consistency, as this will add natural sweetness and moisture to your muffins. Set the bowl aside as you gather the other ingredients for the batter.
Step 3: Combine Wet Ingredients
Add peanut butter, Greek yogurt, honey (or maple syrup), and an egg to the mashed bananas in the bowl. Whisk everything together until you achieve a creamy, smooth mixture. Make sure the peanut butter is well incorporated for a consistent flavor throughout your Healthy Greek Yogurt Peanut Butter Banana Oat Blondie Muffins.
Step 4: Mix in Dry Ingredients
Gently stir in the oat flour and baking powder. Use a spatula to fold the ingredients together until just combined; be careful not to overmix, as this can make the muffins dense. You want to maintain that tender texture reminiscent of blondies!
Step 5: Add Optional Toppings
If you like, fill the muffin cups about three-quarters full with the mixture. For an extra indulgent touch, sprinkle chocolate chips on top or create a delightful swirl of extra peanut butter. This step adds both flavor and visual appeal to your Healthy Greek Yogurt Peanut Butter Banana Oat Blondie Muffins.
Step 6: Bake to Perfection
Place the muffin pan in the preheated oven and bake for 18–20 minutes. Keep an eye out for the tops to become golden brown and slightly crackly. To check for doneness, insert a toothpick into the center; it should come out clean or with a few moist crumbs.
Step 7: Cool and Enjoy
Once baked, remove your muffins from the oven and let them cool in the pan for about 5–10 minutes. This cooling period helps set the gooey tops. Enjoy them warm for the best texture, as they’ll provide that melt-in-your-mouth sensation you crave from Healthy Greek Yogurt Peanut Butter Banana Oat Blondie Muffins.
