Ingredients
- 1 cup unsalted butter room temperature
- 1 cup brown sugar
- ⅓ cup granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 1 ½ cups all-purpose flour or gluten-free flour substitute
- 1 teaspoon baking powder
- 1 ½ teaspoons cinnamon
- ½ teaspoon nutmeg
- ½ teaspoon salt
- 3 cups old-fashioned oats do not use quick oats
- Vanilla Icing:
- 1 ½ cups powdered sugar
- 2-3 tablespoons milk of choice or heavy cream
- 1 teaspoon vanilla extract
- Dash of salt
Instructions
- Preheat oven to 350°F (177°C). Grease and flour a 9x13 baking dish or line with parchment for easy removal.
- In a large mixing bowl, beat butter and sugars until light and fluffy (2–3 minutes).
- Add eggs and vanilla. Beat until smooth.
- In another bowl, whisk flour, baking powder, cinnamon, nutmeg, and salt.
- Add dry ingredients to wet ingredients and mix on low speed until just combined.
- Add oats and mix on low until incorporated. Do not overmix.
- Press dough evenly into prepared pan.
- Bake for 25–35 minutes, until edges are golden and a toothpick inserted in the center comes out with moist crumbs.
- Cool completely in the pan before adding icing.
- Make the icing by whisking powdered sugar, salt, milk or cream, and vanilla in a bowl until glossy. Adjust thickness with more sugar or milk as needed.
- Lift cooled bars from the pan using parchment if used. Cut into bars and drizzle or spread icing on top. Let set before storing.
Notes
- For gluten-free bars, use certified gluten-free oats and a gluten-free flour blend.
- Do not overbake to keep the bars chewy; start checking for doneness a few minutes early.
- For a thicker icing layer, spread instead of drizzling.
- Storage: Store at room temperature in an airtight container for up to 4 days. Freeze (without icing) up to 2 months; add icing after thawing.
