Let’s bake! You’re going to love how simple this is—and how your kitchen smells like a chocolate bakery in under 20 minutes.

Step 1 — Prep Your Pan

Preheat oven to 350°F (175°C).
Line your baking pan with parchment paper.

Step 2 — Mix Wet Ingredients

In a large bowl, whisk together:

• Greek yogurt
• Peanut butter
• Eggs
• Honey
• Vanilla

The mixture turns silky, creamy, and slightly glossy—always a good sign.

Step 3 — Add the Dry Ingredients

Sprinkle in:

• Cocoa powder
• Oat flour
• Baking powder
• Baking soda

Fold gently until everything is just combined. The batter will be thick and brownie-like.

Step 4 — Fold in Chocolate Chips

This is where triple chocolate dreams come true.
Fold through your chocolate chips, saving a few for the top.

Step 5 — Bake

Spread into your pan and sprinkle more chips over the surface.

Bake for 20–25 minutes until:

• The top is set
• A toothpick comes out with moist crumbs
• The kitchen smells like chocolate heaven

Step 6 — Cool and Slice

Let them cool for at least 15 minutes so the texture can set into that irresistible fudgy-soft crumb.

What to Serve With These Muffin Bars

These pair beautifully with:

• A glass of cold milk
• A warm latte or cappuccino
• Greek yogurt on the side for bonus protein
• Fresh berries
• A drizzle of warm peanut butter (just trust me)

For dessert, you can even warm them and add a scoop of vanilla ice cream. Yes, please.

Tips for Making Them Perfect

• Use creamy natural peanut butter for best texture.
• Don’t overbake! Slightly underdone = fudgy perfection.
• Use room temperature ingredients for smoother mixing.
• Add 1–2 tbsp milk if you want a softer, more cake-like texture.
• For EXTRA chocolate, drizzle melted chocolate over the cooled bars.
• Oat flour can be DIY: just blend rolled oats into powder.

These store beautifully:

Room Temperature

Up to 3 days in an airtight container.

Refrigerator

Up to 7 days—they stay super moist.

Freezer
