What You’ll Need

Ingredients for these peanut butter oatmeal cups include:

• Rolled oats: The base of the cups. Use gluten-free rolled oats if needed.
• Almond flour: Adds flavor and lightness; it can be swapped for oat flour.
• Peanut butter: Choose a natural, runny peanut butter (peanuts ± salt only) so it mixes easily.
• Maple syrup: Pure maple syrup is the sweetener here.
• Chocolate chips: For a sweet, chocolatey topping.
• Coconut oil: Optional—helps melt the chocolate smoothly.

See the recipe card below for exact quantities.

Ingredient Substitutions & Additions

• Almond flour: Replace with equal parts oat flour (pulse rolled oats in a blender until fine).
• Peanut butter: Substitute any natural nut or seed butter (sunflower seed butter works well for nut-free).
• Maple syrup: Swap for honey or another liquid sweetener if preferred.

Step By Step Instructions

Step 1: In a bowl, combine rolled oats, almond flour, peanut butter, and maple syrup. Stir until evenly mixed.

Step 2: Spoon tablespoon-sized portions into each cup of a mini silicone muffin pan. Press the mixture firmly with the back of a spoon to create an even, compact layer.

Step 3: In a small bowl, melt the chocolate chips with the coconut oil. Microwave 30 seconds, stir, then heat in 10-second intervals while stirring until smooth. Spoon about 1 teaspoon of melted chocolate onto each cup and spread gently to form a topping.

Step 4: Freeze the tray for 30 minutes or until the chocolate sets. Remove the cups from the silicone pan and serve.

Storage Instructions

Store leftover oatmeal cups in an airtight container in the refrigerator for up to 5 days. For longer storage, freeze in a freezer-safe container for up to 3 months. Let thaw a few minutes at room temperature before serving.

Tips For Success

• Press the mixture firmly into the muffin cups so the cups hold together once chilled.
• Use a runny, natural peanut butter (peanuts ± salt) to ensure easy mixing and binding.
• If you prefer less sweetness, reduce maple syrup slightly but keep enough to maintain stickiness.
• Add extras like chopped nuts, shredded coconut, or sprinkles. If the mixture is dry, stir in a little more peanut butter.
