Choosing the Right Ingredients

Pantry Staples to Keep on Hand

The beauty of 3-ingredient single-serving desserts is that they rely on versatile basics. Stock these items for instant dessert gratification:

• Nut butters (peanut, almond, or cashew)
• Sweeteners (maple syrup, honey, or sugar)
• Ripe bananas (freeze them for longer shelf life)
• Individual yogurt cups (Greek or regular)

Quality Matters

Even with simple 3-ingredient single-serving desserts, quality can make a difference:

• Use real vanilla extract instead of imitation
• Choose high-quality chocolate chips that melt smoothly
• Select fresh fruit at peak ripeness for natural sweetness

Substitutions

Flexibility is key with 3-ingredient single-serving desserts:

• Swap any nut butter for another (sunflower seed butter works for allergies)

• Dairy-free? Coconut oil often works in place of butter
