Here's how:

First, click Layout on your blogger menu. Then click Add a gadget and choose Feed.
Next, type your blog url. Click Continue.
After that, type "Recent Posts" in the title box. And click Save. You're done.
When you have finished adding the gadget, you should place this gadget in a noticable location on your blog, so that your reader will be able to see and click the recent post easily.
Note that your reader may come from Search Engine. If they reached your blog in this way, they won't notice your recent posts because they will be brought to the post where it contains the keyword they type. But if they visit your blog by typing the url on address bar on their browsers, of course they'll be able to see your recent post eventhough you don't have this gadget on the blog.
