Why This Recipe Works

The genius of Crunchies lies in their unique triple-texture combination. Oatmeal provides hearty substance and nutty flavor, while coconut flakes add tropical sweetness and chewy contrast. The surprise ingredient, cornflakes, delivers an unexpected crunch that elevates these cookies from ordinary to extraordinary. The combination of both white and brown sugars creates the perfect balance of sweetness and molasses depth, while the dual leavening agents ensure a light yet satisfying texture.

Ingredients

Base Structure:

• Shortening – Creates tender texture and helps cookies maintain their shape during baking
• All-purpose flour – Provides essential structure and helps bind all ingredients together
• Eggs – Add richness, moisture, and help create the perfect chewy texture

Sweetening Elements:

• White sugar – Contributes sweetness and helps create crispy edges
• Brown sugar – Adds molasses depth and keeps cookies moist and chewy

Leavening Agents:

• Baking powder – Provides lift and creates a light, tender texture
• Baking soda – Reacts with brown sugar for additional rise and golden color
• Salt – Enhances all flavors and balances the sweetness

Texture Components:

• Rolled oats – Deliver a hearty texture and a nutty flavor foundation
• Cornflakes – Add unexpected crunch and subtle corn sweetness
• Coconut flakes – Contribute tropical flavor and chewy texture contrast

Oatmeal Selection Guide

Your choice of oats dramatically affects the final texture:

• Instant Oats: Produce the lightest, most tender cookies with a smoother overall texture. Choose these for a more delicate cookie experience.
• Old-Fashioned Oats: Create the heartiest, most rustic texture with substantial chew and visible oat pieces. Perfect for those who love traditional, substantial cookies.
• Quick-Cooking Oats: Provide moderate heartiness with a slightly more refined texture. These offer the ideal balance between rustic and smooth.

How to Make Oat Crunchies

Prepare for Baking

1. Preheat your oven to 375°F (190°C).
2. Line baking sheets with parchment paper or silicone baking mats.
3. Measure all ingredients and have them ready for mixing.

Create the Cookie Dough

4. In a large mixing bowl, cream together shortening, white sugar, and brown sugar until light and fluffy (about 3-4 minutes with an electric mixer).
5. Add eggs one at a time, beating well after each addition until fully incorporated.
6. In a separate bowl, whisk together flour, baking powder, baking soda, and salt.
7. Gradually add the dry ingredients to the creamed mixture, mixing just until combined.
8. Fold in the rolled oats, cornflakes, and coconut flakes, mixing gently until they are evenly distributed throughout the dough.

Shape and Bake

9. Using a cookie scoop or a rounded tablespoon, drop the dough onto the prepared baking sheets, spacing the cookies about 2 inches apart.
10. Bake for 10-12 minutes, or until edges are golden brown and centers appear set.
11. Remove the cookies from the oven and allow them to cool on the baking sheets for 2-3 minutes before transferring them to wire racks.
12. Cool completely before storing or serving.

Bake at 375 degrees for 10 to 12 minutes.

Cool on a wire rack. Enjoy!

I know you are going to love these coconut oatmeal cookies. This recipe was a family favorite when I was growing up. I can remember my grandmother making these all the time. The cookies would come out of the oven, set on a plate when they were cool enough to handle, and they would soon disappear.
