Wholesome Pantry Staples

Simple ingredients for homemade Do-Si-Dos including oats and peanut butter

Grandma always taught me that the best baked goods start with honest, simple ingredients. For these comforting sandwich cookies, you only need a few familiar items from the pantry. Good quality matters when the ingredient list is this short, so use the best you have on hand.

Natural Peanut Butter: The heart of this recipe. Make sure it is well-stirred so your dough has the right moisture.
Coconut Sugar: Adds a beautiful warmth and caramel note. You can easily use traditional brown sugar if that is what your grandmother used.
Rolled Oats & Oat Flour: Old-fashioned rolled oats give the cookies their signature hearty, chewy texture.
Pure Vanilla Extract: A good splash of vanilla is the foundation of flavor in any heritage bake.
Maple Syrup: Used to lightly sweeten the creamy peanut butter filling, adding a comforting, nostalgic sweetness.

The Classic Heritage Method

Step 1: Preheat the Oven

Begin by warming your oven to 375°F (190°C). There is no need to grease your baking sheet for this honest, simple dough.

Step 2: Mix the Dough

In your favorite large mixing bowl, gently stir together the natural peanut butter, coconut sugar, and the egg until smooth. Pour in the pure vanilla, rolled oats, oat flour, baking soda, and a pinch of sea salt, stirring until the dough forms a beautiful, thick consistency.

Step 3: Scoop and Form

Using a half-tablespoon measure, scoop the dough and roll it into little balls between your palms. Place them on your baking sheet, giving each one a gentle press down with your fingers or a fork, just like Grandma made them.

Step 4: Bake and Cool

Bake the cookies for 8 to 10 minutes, just until the bottoms turn a lovely, light golden brown. Let them rest on the warm baking sheet for about 4 to 5 minutes before moving them to a wire rack to cool completely.

Step 5: Prepare the Filling

While the wholesome cookies are cooling, stir together your peanut butter filling. Mix the peanut butter, maple syrup, and a dash of oat flour in a small bowl until beautifully creamy.

Step 6: Sandwich and Share

Once the cookies are completely cool to the touch, spread a little spoonful of the filling onto the bottom of one cookie. Gently press a second cookie on top to create a perfect sandwich. If you end up with an odd number of cookies, tradition dictates the baker gets to enjoy the spare!

Grandma’s Secrets for the Perfect Batch

For the very best texture, be sure to let your cookies cool completely before adding the filling. If the cookies are even a little bit warm, the peanut butter filling will melt and slip right off the edges. Patience is a virtue in the kitchen, and it pays off wonderfully here.

Keep an eye on the oven, as peanut butter cookies can brown rather quickly on the bottoms.

Stored in an airtight cookie jar, these beauties stay soft and fresh for up to a week at room temperature.

Family Heritage Twists

While this recipe is wonderful exactly as written, you can easily adapt it based on what you have in the pantry. If you have a peanut allergy in the family, almond butter or sunflower seed butter works beautifully to maintain that comforting texture. Adapting recipes to care for our loved ones is a baking tradition as old as time.

You might also try swapping the coconut sugar for regular light brown sugar if that is what you keep on hand.

Sometimes a gentle twist on a classic creates a brand new family favorite.
