Brown Sugar Oatmeal Bars w Whipped Cinnamon Frosting

• Rolled oats – 1½ cups (135g)
• All-purpose flour – ½ cup (60g)
• Baking soda – 1 teaspoon (4g)
• Baking powder – ¼ teaspoon (1g)
• Salt – ¼ teaspoon (1g)
• Cinnamon – ½ tablespoon (4g)
• Brown sugar – ½ cup (100g)
• Vanilla extract – ½ tablespoon (7g)
• Melted butter – 2 tablespoons (28g)
• Oat milk – ¼ cup (60ml)
• Sour cream – 2 tablespoons (30g)
• Large egg – 1 (approx. 50g)

• Heavy whipping cream – ½ cup (120ml)
• Powdered sugar – 2 tablespoons (16g)
• Cinnamon – 1 teaspoon (2g)
• Brown sugar – 1 teaspoon (4g)

In a large mixing bowl, combine all oatmeal bar ingredients and mix until well combined.

Line a loaf pan with parchment paper and pour in the batter, spreading it evenly.

Bake at 350°F (177°C) for 16–20 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.

Let the bars cool in the pan for 1 hour.

Once cooled, cut the bars into triangle shapes or squares.

To make the frosting, add the heavy whipping cream, powdered sugar, cinnamon, and brown sugar to a stand mixer. Whip on high speed for 5–7 minutes until stiff peaks form.

Transfer the frosting to a piping bag and pipe on top of each oatmeal bar.

Tips & Notes:

Store in an airtight container at room temperature for up to 3 days.

You can refrigerate the bars if you prefer a firmer frosting texture.
