Best Chewy Oatmeal Cookies (Soft Centers, Crispy Edges)

Ingredients You'll Need:

• 1 ½ cups all-purpose flour (190g) - Spoon and level the flour to avoid packing in too much, which can make cookies dry.
• 1 tsp ground cinnamon - Adds warmth and depth without overpowering the oats.
• ¼ tsp salt - Balances the sweetness and enhances flavor.
• ½ tsp baking powder - Helps the cookies rise slightly for a softer center.
• ½ tsp baking soda - Encourages spread and gives those golden edges.
• 1 cup unsalted butter, softened (226g) - Butter should be soft but not melted; melted butter will cause excess spreading.
• 1 cup packed brown sugar (200g) - Pack it firmly; the molasses in brown sugar adds moisture and chewiness.
• ½ cup granulated sugar (100g) - Helps create lightly crisp edges and proper spread.
• 2 large eggs - Use room temperature eggs for smoother mixing and better texture.
• 1 tsp vanilla extract - Adds classic cookie flavor
• 3 cups old-fashioned rolled oats (270g) - Stick with old-fashioned oats for the best chewy texture; quick oats can make cookies crumbly.

Optional Add-Ins:

• 1 cup raisins or chocolate chips - This dough works beautifully with chocolate chips, white chocolate, butterscotch chips, nuts, or dried cranberries.

STEP 1: Preheat Oven

Set your oven to 350°F.
Line two baking sheets with parchment paper or spray with nonstick cooking spray. This helps the cookies bake evenly and prevents sticking.

STEP 2: Mix the dry ingredients

In a medium bowl, whisk together 1½ cups all-purpose flour, 1 tsp ground cinnamon, ¼ tsp salt, ½ tsp baking powder, ½ tsp baking soda.

Set this bowl aside - having this mix ready makes it easier when you're working with the wet ingredients.

STEP 3: Cream the butter and sugars

In a large bowl, beat 1 cup softened butter with a hand mixer for about 1 minute until creamy.
Add 1 cup brown sugar and ½ cup granulated sugar.
Beat for another 2-3 minutes, until the mixture is light and fluffy.

STEP 4: Add eggs and vanilla

Crack in 2 large eggs and pour in 1 tsp vanilla extract.
Mix until just combined. Don't overdo it-you want to avoid beating too much air into the batter.

STEP 5: Combine wet and dry ingredients

Slowly pour the dry ingredients into the wet mixture.
Use the mixer on low speed, or switch to a spatula.
Mix until just combined. The dough will be thick.

STEP 6: Fold in the oats

Add 3 cups old-fashioned rolled oats.
Use a spatula to fold them in by hand until evenly distributed.
This gives the cookies their signature chewy bite.

STEP 7: Scoop the dough

Use a cookie scoop or spoon to drop 2 Tbsp of dough per cookie onto the baking sheet.
Leave 2 inches of space between each one-they'll spread out while baking.

STEP 8: Bake

Bake for 11-13 minutes, or until the edges are golden brown.
The centers may still look slightly soft-that's okay!

STEP 9: Cool the cookies

Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack.
They'll firm up as they cool.

Cookies spread too much?

• Your butter may have been too soft or melted.
• Try chilling the dough for 15-20 minutes before baking.
• Make sure you're using parchment paper, not a greased sheet (too much grease = more spread).

Cookies didn't spread enough?

• You may have added too much flour-scoop flour into the measuring cup with a spoon, then level off.
• Check that your baking soda and baking powder are still fresh!

Cookies are dry or crumbly?

• Don't use quick oats-they absorb too much moisture.
• Make sure you used 2 eggs and real butter (not margarine).
• Don't overbake! Pull them out when the centers still look slightly soft.

Too flat and greasy?

• You may have overmixed the dough or used melted butter.
• Always start with softened, not melted, butter.
