30-Minute Keto Lemon Poppy Seed Granola Bars
Bright, nutty keto granola bars with fresh lemon flavor, poppy seeds, and a satisfying crunch from almonds and pumpkin seeds. No baking soda or eggs needed—these hold together with coconut oil and compaction. Perfect for meal prep, grab-and-go breakfasts, or keto-friendly snacking. This version balances tartness from lemon juice with subtle sweetness from erythritol, letting seeds and nuts shine through without overpowering spice or chocolate.
Ingredients
Instructions

- 5
Transfer mixture to prepared baking dish and press down firmly into even, compact layer.
- 6

- 7
Cool completely in dish on wire rack, then use parchment overhang to lift out.
- 8

Tips
Press mixture very firmly into baking dish—this compaction helps bars hold together and prevents crumbling after slicing.
Use parchment paper overhang to lift cooled bars cleanly from dish, making slicing easier and keeping edges intact.
For moister bars, store in refrigerator; they firm up beautifully and last up to two weeks sealed.
Good to Know
Airtight container at room temperature for 1 week, or refrigerator for up to 2 weeks. Freezer-safe for 1 month.
Bars can be fully baked and sliced 2 days ahead. Store covered in refrigerator. Unbaked mixture can be pressed into baking dish and refrigerated overnight before baking.
Cold, at room temperature, or gently warmed. Pairs well with coffee, tea, or Greek yogurt.
Common Mistakes
Underpressing mixture causes bars to crumble—press very firmly into even, compact layer.
Overbaking dries out bars—remove at 20 minutes when edges are golden but center still yields slightly to pressure.
Slicing while warm breaks bars apart—cool completely before cutting with sharp, wet knife.

FAQ
Can I use regular sugar instead of erythritol?
Yes, use 1/3 cup granulated sugar in place of erythritol at 1:1 ratio. Bars will no longer be keto due to higher carbs. Baking time and texture remain unchanged.
What if I don't have poppy seeds?
Use sesame seeds, chia seeds, or flax seeds at same quantity. Omit entirely for seed-free version—texture stays similar. Flavor will shift but bars hold together fine.
How long do these keep and can I freeze them?
Room temperature: 1 week in airtight container. Refrigerator: 2 weeks. Freezer: 1 month in freezer bag or container. Thaw at room temperature for 30 minutes before serving.
