About This Recipe
What It Is
Chocolate Oat No-Bake Squares are a classic no-bake dessert made by coating rolled oats in a glossy chocolate mixture, then pressing everything into a pan to set. Once chilled, they slice into tidy squares with a fudgy center and chewy bite.
Why It Works
This recipe relies on the perfect balance of fat, sweetener, and cocoa powder. Gently heating the mixture blooms the cocoa, deepening the chocolate flavor, while rolled oats provide structure so the squares hold together beautifully.
When to Make It

Chocolate Oat No-Bake Squares (Easy & Fudgy)
- Total Time: 1 hour 15 minutes
- Yield: 16 squares 1x
- Diet: Vegetarian
Description
Rich, fudgy Chocolate Oat No-Bake Squares with a chewy oat bite. Made in one saucepan, pressed into a pan, and chilled until sliceable. No oven needed.
Ingredients
2 cups rolled oats (160 g)
1/4 cup unsweetened cocoa powder (25 g)
1/2 cup creamy peanut butter or almond butter (120 g)
1/2 cup honey or pure maple syrup (120 ml)
1/4 cup coconut oil or unsalted butter (56 g)
1/4 cup milk, any kind (60 ml)
1 tsp vanilla extract (5 ml)
1/4 tsp fine salt
Instructions
1. Line an 8 x 8 inch (20 x 20 cm) pan with parchment paper, leaving an overhang for easy lifting.
2. In a medium saucepan over medium-low heat, stir together nut butter, honey or maple syrup, coconut oil or butter, and milk until melted and smooth, about 3 to 4 minutes. Do not let it boil.
3. Whisk in cocoa powder, vanilla, and salt until the mixture looks glossy and fully combined.
4. Remove from heat. Fold in rolled oats until every oat is coated and the mixture is thick.
5. Scrape mixture into the prepared pan. Press very firmly into an even layer using a spatula or the bottom of a measuring cup.
6. Refrigerate until fully set, 1 to 2 hours.
7. Lift out, slice into 12 to 16 squares, and serve chilled or let stand 10 minutes for a softer bite.
Notes
Oats: Use old-fashioned rolled oats for best structure. Quick oats make a softer, less chewy bar.
Sweetener: Honey sets a bit firmer; maple syrup keeps it softer and vegan.
Too dry: Stir in 1 to 2 tbsp milk (15 to 30 ml) if the mixture seems crumbly before pressing.
Too soft: Add 2 tbsp oats (10 to 12 g) and chill longer.
Storage: Refrigerate up to 7 days, or freeze up to 2 months. Thaw in the fridge overnight.

Key Ingredients & Notes
Rolled Oats
Use old-fashioned rolled oats, not quick oats. Rolled oats provide structure and chew, helping the squares set firmly without becoming mushy.
Cocoa Powder
Unsweetened cocoa powder delivers rich chocolate flavor. Blooming cocoa powder in warm fat intensifies chocolate flavor and creates a smoother texture, a technique well explained by King Arthur Baking.
Nut Butter
Peanut butter is classic, but almond butter or sunflower seed butter works just as well. Choose a creamy style for the smoothest texture.
Honey or Maple Syrup
Either works perfectly. Honey gives a slightly firmer set, while maple syrup keeps the squares softer and fully vegan.
Coconut Oil or Butter
This helps the mixture firm up as it chills. Coconut oil adds subtle richness, while butter adds a classic dessert flavor.
Milk
Any milk works. Dairy milk, almond milk, or oat milk all blend smoothly into the chocolate base.
Vanilla and Salt
A small amount of vanilla enhances the chocolate, while salt balances the sweetness and prevents the squares from tasting flat.
How to Make Chocolate Oat No-Bake Squares
- Prepare the Pan
Line an 8 x 8 inch pan or 20 x 20 cm pan with parchment paper, leaving overhang for easy removal. - Heat the Chocolate Base
In a medium saucepan over medium-low heat, combine nut butter, honey or maple syrup, milk, and coconut oil or butter. Stir constantly for 3 to 4 minutes until fully melted and smooth. Do not let it boil. - Bloom the Cocoa
Whisk in cocoa powder, vanilla extract, and salt. Stir until the mixture looks glossy and thickened slightly. - Add the Oats
Remove the pan from heat. Fold in rolled oats until every oat is fully coated and the mixture looks thick and spoonable. - Press and Chill
Transfer the mixture to the prepared pan. Press firmly using a spatula or the bottom of a measuring cup to create an even surface. Chill in the refrigerator for 1 to 2 hours until fully set. - Slice and Serve
Lift out using parchment, slice into squares, and enjoy.
Pro Tips for Success
- Keep the heat low to avoid grainy chocolate
- Stir constantly so the cocoa does not clump
- Press firmly for clean, sharp slices
- Chill fully before cutting for best structure
- Use parchment for easy removal and neat edges
- If the mixture feels dry, add 1 tablespoon milk
- If too soft, add 2 tablespoons oats and re-press

- Vegan: Use maple syrup and plant-based milk
